 | 2625-25 | Q: Why is the 2625-25 butt diameter 2.375″ rather than 2.344″?A: The… Show more (+) Q: Why is the 2625-25 butt diameter 2.375″ rather than 2.344″?A: The 2.375″ butt diameter corresponds to the 2.500″x0.065″ tube’s bore, which is nominally 2.370″ (2.500″ minus 2×0.065″ = 2.370″). The 0.005″ butt-to-bore clearance is intentional for slide-fit assembly. The 2.344″ butt on the 2626-25M corresponds to the 0.083″ wall tube bore (2.334″ nominal), which is significantly smaller — these two butt diameters are NOT interchangeable between tube walls.Q: Is there a meaningful performance difference between 0.065″ and 0.083″ wall at 2.500″ tube?A: At normal production driveshaft RPM, both walls provide adequate torsional stiffness at 2.500″ OD. The 0.083″ wall provides approximately 27% more wall-section area, offering better resistance to denting from road debris and a marginally higher column buckling load — relevant only in severe off-road conditions. For standard passenger car and light-truck use, the 0.065″ wall is entirely adequate.Q: What U-joint does the 2625-25 require?A: 7260 series, 1.125″ cap OD. The 2.500″ tube in the 7260 series is an unusual combination — most driveshaft shops will default to suggesting a 1310 or 1330 joint for 2.500″ tube. The 7260 is specified here for angle capacity, not just torque. See our U-joint listings for the correct 7260 part number.

This combination is used on light-medium applications where the angular requirements or torque rating of the 7260 joint are needed but the shaft speed and length allow a smaller tube. The 2.344″ butt diameter is the same standard used across all 2.500″x0.083″ weld yokes in multiple series (1330, 1350, CVJ, 7260) — tube preparation is interchangeable. The CL-to-weld at 1.625″ is slightly longer than the smaller-series yokes at this tube size, reflecting the 7260 yoke body’s longer profile.7260 joint required at 1.125″ cap OD; 2.500″ tube yokes in the 1330/1350 series use a smaller 1.062″ or 1.188″ cap — verify series match2.344″ butt diameter — consistent with all 2.500″x0.083″ weld yokes; no special tube preparation needed1.625″ CL-to-weld — slightly longer than 1330/1350 equivalents at same tube size; account for the difference in shaft length calculationSteel construction; standard for all production 7260 applications at this tube sizeAn installation risk: at 2.500″ tube with a 7260 joint, the tube-to-joint capacity ratio is tighter than at 3.000″ or 4.000″ tube. Any out-of-round or dented tube will produce first-order imbalance after welding, and the smaller tube provides less rotational inertia to dampen it. Inspect the tube for ovalizing before installation. This weld yoke is appropriate for street and normal commercial applications within the 7260 torque rating.

The 2.455″ butt diameter is derived from the non-standard tube bore and is unique to Mazda-series components in this family. A common error when rebuilding Mazda driveshafts is substituting the 2.500″ tube variant (2625-25 or similar) and assuming the 0.070″ diameter difference is negligible. In fact, the 0.070″ pilot OD mismatch produces a visible gap between yoke and tube bore that results in a weld with insufficient penetration at the tack points, causing the yoke to walk out of center during final welding and producing unacceptable runout. Use only the Mazda-specific 2.570″ variants for these applications. This weld yoke requires the correct 7260-series U-joint for Mazda applications.

The 0.031″ butt diameter increase (2.875″ vs. 2.844″) reflects the thinner wall reducing the bore size, requiring a proportionally larger pilot for the same centering tolerance. This is the lighter assembly option for Chrysler/Mopar driveshafts where tube weight reduction is more critical than added wall-section strength.The 3.000″x0.065″ specification appears on lighter Chrysler/Dodge trucks and minivans that use the 7260 joint for its angular capacity rather than peak torque requirements. At 1.625″ CL-to-weld, the weld joint is positioned consistently with the 7260-series geometry standards. Balance post-weld to 0.10 oz-in residual, which is the standard specification for this tube and series combination. This weld yoke requires a 7260-series U-joint at the cap bore; consult the Spicer 7260 cross-reference for the correct part number for your specific Chrysler application.

A measurement near 1.625″ confirms the 7260-series Chrysler specification. If the measurement is closer to 1.812″, the shaft may have been previously rebuilt with a GM 7290 yoke — a common workshop improvisation that works dimensionally but puts the wrong joint series at risk. This weld yoke is the correct OEM-geometry replacement for Chrysler 3.000″ tube 7260 applications.

 | 2626-32 | Series Note: Compare to 2926-32 (GM 7290, same tube spec, 1.812″ CL-to-weld)… Show more (+) Series Note: Compare to 2926-32 (GM 7290, same tube spec, 1.812″ CL-to-weld) — the 7260 variant 2626-32 uses a 1.625″ CL-to-weld, 0.187″ shorter than the GM equivalent. This dimensional difference between the Chrysler and GM variants of the same tube size means these yokes are not cross-brand interchangeable even though tube OD, wall, and series cap size appear similar.The 2626-32 addresses Chrysler/Mopar 3.250″x0.065″ tube driveshaft applications in the 7260 series. The 0.187″ difference in CL-to-weld compared to the GM 7290 equivalent (2926-32) is significant — swapping to the GM dimension would effectively shorten the assembled shaft by 0.187″, which shifts the rear U-joint operating angle and can cause contact between the driveshaft tube and tunnel components at ride height. Always source the correct brand-specific weld yoke when rebuilding a Chrysler truck driveshaft. The 7260 U-joint series carries the torque at this tube diameter; see the 7260 U-joint catalog for the correct cap dimensions for Chrysler applications.

However, the U-joint series is different — 7260 joints are Chrysler-spec and not interchangeable with GM 7290 joints despite sharing the same cap OD. Installing the wrong joint in the wrong yoke ear bore will result in incorrect cap seating and immediate bearing failure.Q: How do I confirm my Chrysler truck needs a 7260 yoke?A: Reference the original OEM service part number from the chassis service manual and cross-reference it to the 7260 or 7290 series using a standard U-joint cross-reference catalog. The vehicle build tag or RPO codes on Chrysler trucks can also indicate the driveshaft specification. If in doubt, measure the original yoke ear bore diameter — both series measure 1.125″ OD on the cap, but the bore depth and retaining ring groove position differ between them.Q: What U-joint part number does the 2626-40 require?A: Spicer 5-178X or 5-760X for the 7260 series. Verify against the Spicer cross-reference guide for your specific application before ordering the U-joint separately.

The 7260 joint uses a 1.125″ cap diameter identical to the 7290 in OD, but the cap length and internal geometry differ — do not assume 7290 and 7260 joints are interchangeable based on cap OD alone. Verify the correct joint series for your application before purchasing the joint.7260 series — Chrysler/Mopar heavy truck application; different U-joint from 7290 series despite shared cap OD4.000″ x 0.083″ tube — same tube spec as 2926-41 (GM 7290 variant); both use 3.844″ butt diameter2.000″ CL-to-weld — identical to the 7290 variant; consistent weld geometry across series at this tube sizeConfirm your vehicle is Chrysler/Mopar specification before using 7260 components — mixing 7260 and 7290 joints with wrong-series yokes causes immediate cap seat failureMatch with a 7260-series end yoke at the pinion for consistent series capacity through the assemblyTip: 7260 yokes from Chrysler production vehicles are typically unmarked — the series number was not stamped on OEM production components. Identify by measuring the cap bore: a clean, freshly-machined bore at 1.125″ on an unmounted yoke ear confirms the cap size, but you still need to verify series (7260 vs 7290) by cross-referencing the OEM part number from the vehicle service manual.

This combination — 2.750″ tube with 7290 U-joint capacity — appears on lighter GM trucks and some transfer case-to-differential shafts where a large-cap joint is required for angular or torque reasons but the tube diameter can be kept relatively small for packaging. The 2.625″ butt diameter and 1.750″ CL-to-weld represent the standard compact geometry for this configuration. Note that 2.750″ tube at 0.065″ wall has a relatively modest wall-section modulus — appropriate for normal production power levels but marginal for performance applications with substantially higher torque. Consider stepping up to 0.083″ wall if the vehicle has been modified beyond OEM torque levels. This weld yoke requires the standard 7290 joint at 1.125″ cap; no other series is compatible at this yoke ear bore size.

The 0.031″ butt diameter difference is easy to overlook when ordering, but the consequence is a loose or non-seating pilot at assembly. Verify your tube wall with a micrometer or ultrasonic gauge before ordering if the wall stamp on the existing tube is illegible.The thicker 0.083″ wall on the 2926-30 application provides higher column strength and better resistance to dent damage from road debris compared to the 0.065″ version. This makes the 2926-30 appropriate for vehicles that operate off-road or in environments where the driveshaft is exposed to impact loading. The 7290 U-joint at 1.125″ cap diameter carries the torque at both ends; see our series listing for the correct 7290 U-joint complement. Balance specifications for 3.000″ tube 7290 assemblies are 0.10 oz-in residual maximum.

Hot-straightening is not recommended on 7290 weld yoke assemblies — the weld yoke material is not rated for the thermal cycling involved in straightening, and distorted assemblies should be scrapped rather than re-formed. Maintain proper welding technique and fixturing to hold runout within 0.010″ total on the first attempt.

Verify the 7290 U-joint you intend to use matches this retention style. Snap-ring style mismatches result in loose joint retention and rapid failure.The 2926-32 steps down to a 3.250″x0.065″ tube from the 4.000″ variants, addressing lighter-duty 7290-series applications where the smaller tube diameter is appropriate for the shaft torque and speed requirements. The 3.130″ butt diameter is consistent with the standard step-down calculation for 0.065″ wall (3.250″ – 2×0.065″ = 3.120″ bore; 3.130″ butt creates a slight interference that centers the yoke). The 1.812″ CL-to-weld is compact for a 3.250″ tube — confirm this dimension matches the required shaft length when recalculating the tube cut. This weld yoke is steel, suitable for all standard GM 7290-series medium-duty applications in the 3.250″ tube diameter class.

The difference is tube wall thickness: the 2926-40 fits a 0.065″ wall tube (3.875″ butt diameter), while the 2926-41 fits a 0.083″ wall tube (3.844″ butt diameter). The 0.031″ butt diameter difference reflects the 0.018″ wall change per side. Using the wrong wall variant will result in either a loose pilot (2926-40 butt in a thick-wall bore) or a non-seating interference fit (2926-41 butt in a thin-wall bore).Q: Is 0.065″ wall adequate for a heavy GM truck driveshaft?A: GM used 4.000″x0.065″ tube on lighter-duty applications within the 7290 series. At 4.000″ OD, the diameter provides sufficient critical speed rating for typical truck driveshaft RPM ranges. The 0.065″ wall provides adequate column strength for production torque levels — however, for upgraded powertrain applications above factory torque, a heavier 0.083″ or 0.095″ wall is recommended to provide a larger safety margin against tube collapse under peak torsional stress.Q: Do I need a special U-joint with this yoke?A: Yes — the 7290 series requires a 7290 U-joint at 1.125″ cap diameter. Spicer 5-760X or GKN equivalent. Never install a 1310 or 1350-series joint in a 7290-ear yoke.

The 7290 U-joint uses a 1.125″ cap diameter — significantly larger than the 1.062″ 1310 cap — and carries considerably higher torque capacity. The 2926-41 fits a 4.000″x0.083″ tube; at 3.844″ butt diameter, the pilot provides a tight, self-aligning fit in the tube bore. The 2.000″ CL-to-weld is a balanced dimension for this tube size — long enough to allow proper weld cooling away from the joint, compact enough to keep the overall assembly length controlled.7290 series — 1.125″ cap diameter U-joint; do not substitute 1310 (1.062″ cap) or 1350 (1.188″ cap) joints3.844″ butt diameter — requires clean, round tube bore; verify existing tube is not ovalized2.000″ CL-to-weld — standard dimension for 4″ tube 7290 applicationsSteel construction; standard for all OEM GM medium-duty applications in this seriesMatch with a 7290-series end yoke at the pinion for a consistent series assemblyIf the original GM truck driveshaft used a 7290 U-joint and the yoke is being replaced due to fretting corrosion at the ear bores, always bore-check the yoke ears before installing a new joint. 7290 ear bores corrode in a slightly oval pattern — even 0.003″ of oval distortion will cause the needle bearing cup to rock and fail within months of reinstallation.

The 9951-22 series designation indicates a compact light-duty U-joint series used on the front (transfer-case-to-front-differential) shaft of Infiniti AWD and 4WD models. The 1.750″x0.095″ tube is unusually small for a front shaft — this design is optimized for the Infiniti’s front-shaft package constraints where underbody clearance is minimal.The 1.571″ butt diameter is specific to Infiniti’s OEM tube specification and may not correspond to any standard SAE tube size — verify the existing driveshaft tube OD and bore before ordering. The 1.625″ CL-to-weld is short, which means weld heat management is especially important: use a low-heat input process and multiple short passes rather than a single continuous bead to minimize heat penetration into the U-joint working area. This front-shaft weld yoke should be replaced as a matched set with the companion front yoke and U-joint to maintain OEM balance specification.

The tube wall difference of 0.018″ per side changes the butt diameter by 0.031″ — a small difference that translates to a noticeable fit variation at assembly. Inserting a 2.375″ butt into a 0.083″ wall tube bore (nominal 2.334″ inside diameter) will produce a 0.041″ radial interference; the yoke will not seat. Confirm tube wall thickness before ordering.Companion parts 1452-8602-8602 and 1453-860 are required for a complete CV assembly. Note the companion socket designation (1452-8602-8602) uses a doubled suffix versus the 1426-863’s 1452-8602 — this indicates a different socket depth or body profile. Always match this weld yoke to its designated companion parts and verify the M8-1.25 thread pitch before sourcing fastener hardware.

The butt diameter difference (0.031″) reflects the different tube bore sizes — never mix these two yokes with the wrong tube wall thickness, as the pilot will either be loose (thin yoke in thick-wall tube) or will not seat (thick yoke in thin-wall tube).The 2252-681 is the thin-wall IRS weld yoke at 0.065″ wall, providing a lighter assembly than the 0.083″ variant while maintaining the same CVJ IRS geometry. The 3.500″ centerline-to-weld is identical to the 2252-683, confirming both use the same CV socket body depth. The 2.375″ butt diameter is the standard pilot for 2.500″x0.065″ tube across the CVJ and standard series. Application is specifically for independent rear suspension driveshaft builds where the lighter tube weight reduces unsprung mass at the axle — an advantage in performance applications where IRS geometry is already optimized for handling. Complete the CV assembly with matching IRS CV centering ball hardware; see our CV joint kit listings for the correct companion components.

At 3.500″ centerline-to-weld, it positions the weld point significantly further from the U-joint than standard CVJ weld yokes — this is required by the IRS CV socket body depth, which is longer than the conventional front-shaft CV socket.Q: Do I need the CV ball kit with this yoke?A: Yes — the note on this part explicitly states: add CV ball kit, part number 2252-681C. The weld yoke alone does not function as a CV joint; the ball, socket, and spring assembly are required to create the constant-velocity action. Order both parts simultaneously.Q: Why is the CL-to-weld distance 3.500″ on an IRS yoke but only 1.250″–1.750″ on front-shaft CVJ yokes?A: IRS CV joints in independent suspension systems must accommodate larger suspension travel angles and use a deeper CV socket design to maintain centering across the full articulation range. The deeper socket requires the weld joint to be positioned further back on the tube to maintain the correct effective tube length and CV socket engagement depth. Using a shorter CL-to-weld front-shaft yoke with an IRS CV kit will result in the socket bottoming against the yoke before full compression travel is reached, causing binding.

 | 2526-251 | The 2526-251 uses the shortest centerline-to-weld dimension in the 2.500″ tube CVJ… Show more (+) The 2526-251 uses the shortest centerline-to-weld dimension in the 2.500″ tube CVJ family at 1.390″. This compact dimension indicates the CV centering socket (2552-1001) is a shallow-depth design, requiring the weld joint to sit as close to the U-joint centerline as is practically achievable without weld heat compromising the joint. The corresponding companion socket 2552-1001 is dimensionally different from the 2552-1002 used with the 2526-253 — do not mix these companion sets.1.390″ CL-to-weld — shortest in the 2.500″ CVJ series; compact design for tight package constraints2.344″ butt diameter — same as all other 2.500″ tube CVJ weld yokes; tube preparation is identicalMust be used with 2552-1001 CV socket and 2553-252 front tube yokeThe 0.110″ difference in CL-to-weld vs. the 2526-253 shifts the CV socket seating depth and changes the centering ball preload — not interchangeable despite identical tube specComplete the assembly with a CV joint kit for centering ball, socket spring, and retaining hardwareVerify the tube cut length with the correct weld yoke in hand before final assembly. Substituting a longer CL-to-weld yoke will effectively shorten the tube — a 0.110″ error here translates directly to a 0.110″ error in assembled shaft length, which can push the rear U-joint out of its working angle specification by a measurable amount.
