The 1350 U-joint uses a 1.188″ cap diameter, the same OD as the 1410, so series identification must be based on journal length and bearing cup depth rather than cap OD alone when servicing used assemblies.The 3-28-57 fits a 3.000″x0.083″ tube with the standard 2.844″ butt diameter (3.000″ – 2×0.083″ = 2.834″ bore; 2.844″ butt = 0.010″ interference) and 2.000″ CL-to-weld. This combination is commonly found on F-series rear shafts, Dodge/Ram trucks, and 4WD front shafts across multiple production decades. The 1350 U-joint (Spicer 5-213X cross-reference family) provides adequate capacity for 3/4-ton and light 1-ton applications. For sustained high-torque drag racing or very heavy towing, stepping up to the 1410 or 1480 series at this tube size provides a meaningful safety margin.

The “SOLID BUTT” note on this part indicates the yoke’s stub end is machined as a solid cylindrical stub rather than a hollow stepped pilot — a different geometry used when the tube is butt-welded to a solid stub without an internal shoulder to pilot against. The 2.345″ butt diameter matches the 2.560″ tube’s external seating geometry for this style of joint.The machinist’s note on this part is also significant: “CAN BE TURN DOWN TO 2.000 X 0.125″ — meaning the solid stub can be machined in a lathe to a 2.000″ OD, allowing the yoke to be used with 2.000″x0.125″ tube (different application). This dual-fitment capability makes the 1326-20-S a versatile component for shops that prefer to stock fewer SKUs. The Toyota 1351-20 U-joint series is required at the ear bore; confirm the series before ordering the complement joint. At 2.000” CL-to-weld, the weld geometry is the same as the 1326-21 — these two parts appear very similar and must be distinguished by the solid-butt versus hollow-pilot geometry at the tube end.

The 0.250″ longer CL-to-weld on the 1326-21 versus the 2326-26 (both at the same 2.560″ tube) indicates the 1351-21 joint body is taller than the 2351-20, requiring the weld to be positioned further back. Mixing the two series weld yokes on the same Toyota shaft is inadvisable — the resulting mismatch in effective length will shift the rear joint operating angle and may cause vibration or interference with underbody components. This weld yoke is appropriate for all stock Toyota truck applications in this series.

 | 4126-405A | Wall Thickness Note: The 4126-405A is for 4.000″x0.083″ tube (butt dia 3.850″)… Show more (+) Wall Thickness Note: The 4126-405A is for 4.000″x0.083″ tube (butt dia 3.850″), while the 4126-41A is for 4.000″x0.125″ tube (butt dia 3.757″). The 0.093″ butt diameter difference reflects the 0.042″ wall difference per side. Using the 0.125″ wall yoke butt (3.757″) in a 0.083″ wall tube bore (3.834″ bore) will produce a loose-fit pilot. Using the 0.083″ wall yoke butt (3.850″) in a 0.125″ wall tube bore (3.750″ bore) will not seat. Match butt to tube wall.The 4126-405A provides an aluminum 1410-series option for the lighter 0.083″ wall variant of the 4.000″ tube. The thinner wall reduces rotating mass relative to the 0.125″ wall, improving powertrain response at the cost of slightly reduced impact resistance. At 2.500″ CL-to-weld, this is 0.375″ shorter than the 4126-41A (2.875″ CL) — select between these variants based on your required total shaft length calculation. Aluminum welding procedure applies: de-oxidize immediately before welding, use correct filler wire, and allow full cooling before joint installation. This weld yoke requires the 1410 U-joint at 1.188″ cap; see our U-joint category for the correct 1410-series part.

The sole difference is CL-to-weld: 2.375″ on the 4126-406A versus 2.875″ on the 4126-41A. The shorter CL produces a shaft that is 0.500″ longer for the same tube cut, or requires a tube 0.500″ shorter to hit the same total shaft length. Select based on the required assembled shaft length.Q: Is a 2.375″ CL-to-weld safe for aluminum welding on a 0.125″ wall tube?A: Yes — 2.375″ provides adequate clearance from the U-joint journal area, and the 0.125″ wall is robust enough that standard aluminum MIG welding technique (4043 or 5356 wire, interpass temp below 150 degrees F) produces acceptable welds without risk of burn-through. The tighter heat-affected zone boundary at 2.375″ means weld cooling should be allowed fully before pressing in the U-joint — allow 30 minutes at ambient temperature before joint installation.Q: Do the 4126-41A and 4126-406A require different tube preparation?A: No — both use the same 3.757″ butt diameter and the same tube OD and wall spec. Tube cut length is the only variable that differs. This weld yoke is a direct length-variant of the 4126-41A with no other differences.

The 4.000″x0.125″ tube provides a good balance of critical speed and rotational inertia for high-performance street and club racing applications with wheelbase-to-speed requirements in the moderate range.1410 series: 1.188″ cap diameter; verify U-joint series before pressing in replacement joint3.757″ butt diameter — step-down from 4.000″ OD at 0.125″ wall: 4.000″ – 2×0.125″ = 3.750″ bore; 3.757″ butt provides 0.007″ interference2.875″ CL-to-weld — same as 4126-50A (5.000″ tube variant); consistent geometry across tube sizes in this seriesAluminum: 6061-T6 typical; use stainless wire brush to remove oxide before weldingPerformance application: complete with 1410-series U-joint for consistent drivetrain capacity through the assemblyFor performance builds where the driveshaft span is 48–56″ and peak shaft speed exceeds 4,500 RPM, the 4.000″ tube critical speed (approximately 5,200 RPM for a 52″ span at 0.125″ wall) is marginally adequate. If the calculated critical speed margin is under 25% above the maximum operating RPM, step up to the 5.000″ tube family for the additional safety margin against resonant vibration onset.

At 0.063″ wall, the tube provides the absolute minimum material necessary for torsional integrity — this is a weight-optimized specification for motorsport applications where driveshaft unsprung and rotating mass reduction is a primary engineering objective. The 4.888″ butt diameter is proportionally larger than the 0.125″ wall variants (4.757″) because the thinner wall produces a larger tube bore, which requires a proportionally larger pilot for the same centering tolerance.The 4.109″ CL-to-weld is the longest in the 5.000″ aluminum 1410 family. This distance is required because welding a 0.063″ wall tube demands extremely careful heat management — even with 4043 MIG wire and a skilled welder, weld-zone wall thinning can reduce local wall to 0.045″–0.050″, which is marginal for production-use torsional loads. The extended CL-to-weld moves the weld well away from the U-joint journals, reducing the possibility of heat-induced distortion at the ear bores. This weld yoke should be welded only by experienced aluminum driveshaft fabricators with specific experience on thin-wall tube.

The 3.000″ CL versus 2.875″ on the 4126-50A produces a shaft that is 0.125″ shorter for the same tube cut length, or requires a tube 0.125″ longer to achieve the same total shaft dimension. Select between these two CL variants based on the required total shaft length after calculating both end yoke CLs and the tube length.The 1410-series ear bore at 1.188″ cap diameter distinguishes this aluminum yoke from the 1480-series 4826-506A despite identical external tube interface dimensions. A 1480 joint pressed into a 1410 yoke ear bore will have 0.187″ radial interference that makes installation impossible without reaming. A 1410 joint in a 1480 bore will have 0.187″ clearance — loose and immediately dangerous. Verify the correct joint series for your weld yoke before assembly. Pair with a 1410-series U-joint for full performance compatibility.

Swapping to 1480 later requires re-machining the ear bores — not a practical field modification. The 1480 series adds only ounces of additional weight in the aluminum weld yoke format, making it the better long-term investment for any build with known future power increases planned.

If upgrading from 0.083″ to 0.095″ wall tube for increased strength, you must also change from this yoke to the 3-28-557U — the 0.031″ butt diameter difference prevents interchangeability between tube walls.The 3-28-557 is the standard flush-pilot 1410-series weld yoke for 3.500″x0.083″ tube. The 3.344″ butt and 2.125″ CL-to-weld are the standard 1410 series dimensions for this tube specification, consistent with the 3.344″ butts used in the 1350-series at the same tube OD and wall. The 1.188″ cap bore distinguishes this yoke as 1410 series versus 1350-series (1.062″ cap at the same tube size). Inspect your original U-joint cap OD with a micrometer before ordering a replacement yoke — the 1350 and 1410 series differ by 0.126″ in cap OD, which is easily visible once you know to measure it.

The 2.844″ butt diameter is the expected step-down: 3.000″ – 2×0.083″ = 2.834″ bore; 2.844″ butt provides 0.010″ interference for centering. This is a conventional flush-weld design unlike the stepped-bore 3-28-97U, which uses a 2.344″ pilot for a stepped-bore tube.Q: Is the 3-28-97 the same as the 2-28-97 or 3-28-97U?A: No. The 3-28-97 (this part, 3.000″x0.083″, 2.844″ butt, 2.125″ CL) is different from the 3-28-97U (which uses a smaller stepped butt of 2.344″ for a different tube configuration). The “U” suffix on the Spicer part indicates a different yoke body design for a specific OEM application. The 3-28-97 is the standard production replacement for conventional 3.000″x0.083″ tube assemblies.Q: What U-joint goes with the 3-28-97?A: The 1410-series U-joint, 1.188″ cap diameter. Spicer 5-1310X or equivalent. Do not substitute a 1350-series (1.062″ or 1.188″ cap) — verify the exact cap OD against the 1410 specification in your U-joint catalog before purchasing.

Like the 3-28-97U (3.000″ tube), the butt diameter appears smaller than the expected step-down from tube wall: 3.500″ – 2×0.095″ = 3.310″ bore, but butt diameter is 2.844″ — a 0.466″ step. This confirms a stepped-bore yoke design where the pilot diameter is significantly smaller than the tube bore, engaging a different portion of the tube interior. This design is found on some OEM Chrysler/Dodge applications where the tube bore steps internally. Verify the tube bore profile on your specific vehicle before ordering.1410 series: 1.188″ U-joint cap — confirm before sourcing complement joint3.500″ x 0.095″ tube with 2.844″ stepped butt — not a standard flush-pilot yoke; tube must have matching internal step2.125″ CL-to-weld — same as 3-28-97U; consistent Spicer 1410-series geometry across tube sizes“U” suffix: OEM specification designation for this Spicer partThis weld yoke is appropriate for 3/4-ton and light 1-ton truck driveshaft applications in the Chrysler/Mopar catalogIf the tube bore on your replacement driveshaft tube does not match the 2.844″ stepped pilot of the 3-28-557U, use the non-stepped variant 3-28-557 instead, which uses a 3.344″ flush pilot for a standard 3.500″x0.083″ tube. Attempting to weld a stepped-pilot yoke into a non-stepped tube will result in a loose fit and weld failure.

The 2.344″ butt diameter is notably smaller than what would be expected for a 3.000″ tube — this suggests a stepped-bore yoke design where the pilot engages deep inside the tube rather than at the tube face, similar to the 1610-series approach noted earlier. Confirm your tube bore geometry matches this pilot before ordering this Spicer weld yoke. Cross-reference against Spicer’s catalog for OEM fitment confirmation on your specific truck model and year.

This combination — a relatively small OD with a very heavy wall — provides exceptional resistance to dent and bend damage from rock strikes and trail obstacles while accepting the 1410 joint’s high angular capacity. The 0.157″ wall is nearly twice as heavy as the 0.083″ wall used in standard street applications at similar OD, producing a tube section modulus appropriate for sustained off-road impact loading.The 2.129″ butt diameter is specific to this heavy-wall spec: 2.283″ – 2×0.157″ = 1.969″ bore; 2.129″ butt creates a 0.160″ interference — a tight press fit that holds the yoke firmly before welding. The 2.165″ CL-to-weld provides adequate heat-affected zone clearance for the thicker tube wall, which requires higher heat input and longer dwell time during welding. This Spicer off-road weld yoke requires the 1410-series U-joint at 1.188″ cap — the ideal complement for 4WD front shaft applications on heavy lifted trucks where both angular capacity and impact resistance are priorities.

The 4.500″ tube at 0.083″ wall provides approximately 10% less weight than the 5.000″x0.125″ combination — relevant when total shaft weight matters more than maximum critical speed. The trade-off is a lower critical speed ceiling at 4.500″ OD versus 5.000″ OD for the same span.The 4826-45A offers a lighter build option in the 1480 aluminum family. The 4.344″ butt diameter corresponds to the 4.500″x0.083″ tube bore (4.500″ – 2×0.083″ = 4.334″ bore; 4.344″ butt provides 0.010″ interference). The 2.250″ CL-to-weld is compact, keeping the yoke body short while maintaining adequate clearance from the joint journals during MIG welding. Aluminum welding protocol applies: remove oxide with stainless wire brush immediately before welding, use 4043 or 5356 filler, and maintain low interpass temperature to avoid softening the 6061-T6 heat-affected zone below T4 temper. This weld yoke requires the standard 1480-series U-joint at 1.375″ cap diameter. Neapco and Spicer 1480 joints are both compatible at this ear bore.

All other dimensions are identical: same 5.000″x0.125″ tube spec, same 4.757″ butt diameter, same 1480 series, same aluminum material. The 0.125″ difference changes the effective shaft length when substituting between them.Q: Why are there three CL-to-weld variants (2.875″, 3.000″, 3.500″) for the same tube spec in the 1480 aluminum family?A: Different vehicle platforms and custom build configurations require different effective shaft lengths. Rather than offering one-size-fits-all with the shortest yoke and requiring tube extension, three CL-to-weld variants allow shaft fabricators to hit the exact assembled length with a standard tube cut. Select the variant whose CL-to-weld combined with the available tube stock length produces the required total shaft length.Q: Can I mix brands (Neapco A48-28-5012 at one end and 4826-506A at the other) on the same shaft?A: Yes — the 5.000″ tube, 4.757″ butt, and 1480-series U-joint interface are consistent across brands. The only dimension that changes shaft length is CL-to-weld; account for both end yoke CL dimensions when calculating tube cut length. This weld yoke is fully interchangeable with other brand-equivalents at the same series and tube spec.

At 2.875″ CL-to-weld, it is 0.625″ shorter than the Neapco A48-28-5012 (3.500″ CL) and 0.125″ shorter than the 4826-506A (3.000″ CL). These 0.125″–0.625″ differences between variants in the same series affect total assembled shaft length — always measure the CL-to-weld on the original yoke before ordering a replacement.4.757″ butt diameter — standard for all 5.000″x0.125″ aluminum weld yokes in the 1480 series; tube prep is consistent across variants2.875″ CL-to-weld — shorter CL variant; produces a slightly longer tube section for a given total shaft lengthAluminum construction — 6061-T6 typical; requires stainless wire brush oxide removal immediately before MIG welding1480-series U-joint (1.375″ cap) required at the ear boreThis weld yoke is appropriate for performance street builds where driveshaft weight reduction is a priorityAluminum weld yoke selection: the 0.125″ wall 5.000″ tube used with this yoke is the most common performance driveshaft tube specification for high-horsepower street cars and light competition use. At 5.000″ OD and 0.125″ wall, the critical speed of a 50″ span exceeds 5,500 RPM driveshaft speed — adequate for most applications up to 200 MPH in rear-drive passenger cars. Above that, two-piece shaft configurations with a center support bearing become necessary.

The Neapco designation uses the “A” prefix to indicate aluminum and “48” to denote the 1480 series — a naming convention that simplifies identification in complex multi-brand driveshaft shops. At 3.500″ CL-to-weld, this is the longest in the 5.000″ aluminum weld yoke family — 0.750″ longer than the UDS 4826-50A (2.875″ CL). The additional weld distance provides maximum clearance from the joint journals during MIG welding, reducing the risk of heat affecting the yoke ear bore hardness. Neapco aluminum yokes are machined from 6061-T6 billet and are compatible with aluminum tube at 5.000″ OD. Pair with a 1480 U-joint at 1.375″ cap diameter; Spicer 5-280X or Neapco equivalent cross-reference.

The wall difference of 0.012″ per side produces a 0.023″ butt diameter difference (3.344″ vs. 3.321″). While this might seem trivial, at 3.500″ tube the 0.023″ difference represents a meaningful proportion of the pilot clearance — a 3.321″ butt inserted into a tube bored for 3.344″ will have 0.023″ radial clearance (0.0115″ per side), which is enough to allow the yoke to sit off-center before tack welding if not hand-held during tacking. Always match the butt diameter to the actual tube wall in your application.Spicer-branded components in this series are machined to tighter dimensional tolerances than generic aftermarket alternatives, which benefits final assembly balance. The Spicer 1480 joint (cross-reference 5-280X) uses a proprietary needle bearing geometry in the 1.375″ cap that provides higher dynamic load capacity than generic replacements at the same nominal cap OD. For production-quality truck driveshaft repairs, use Spicer components throughout the assembly.
