This level of correction is required on new large-diameter driveshaft fabrications (4+ inch tube) or on driveshafts where tube straightness is at the edge of tolerance. The stainless steel construction makes this the correct choice for marine, agricultural, or off-highway applications where corrosion is a long-term concern.SKU232698-1MaterialStainless SteelWeight0.500 lbs / 227 gStyle6Welding stainless balance weights to carbon steel tube requires ER309L filler metal to bridge the dissimilar material joint. Full perimeter weld is required at 0.500 lbs — centrifugal force at 2,500 RPM on a weight this size reaches approximately 100 lbs. A tack-only weld will fail.

At this mass level, the weight is used exclusively for final-pass corrections — after primary weights have brought the residual below 0.20 oz, the 230701-1 closes the remaining gap. Professional driveshaft shops balance to 0.10 oz-in residual for highway applications; this weight is the tool for the last step.Q: When does 230701-1 apply vs. BW1A or 231817-9?A: Series selection depends on tube geometry and original equipment designation. If the shaft carries existing Spicer 230701-series weights, use the same family for consistency. If balancing a new or generic tube, any trim weight in the correct mass range will work.SKU: 230701-1Weight: 0.15 ozCross-reference: Spicer 230701-1 Show less (-) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

The 231536 series uses a different physical profile than the 231546 series, so confirm the correct series for your application from the original part markings or the balancing shop’s specification.SKU: 231536-2Weight: 0.66 ozSeries: 231536Cross-reference: Spicer 231536-2After welding, allow the shaft to cool to ambient temperature before running the final balance check. A hot shaft will have thermally expanded weld metal that slightly shifts the correction mass distribution — re-checking while the shaft is still warm gives a false reading.

Corrections above 1 oz typically indicate a structural cause — weld build-up asymmetry, tube wall variation, or a previous incorrect balance weight that must be removed before adding the 231536-3.SKUWeight231536-20.66 oz231536-31.05 ozBefore welding a correction weight over 1 oz, inspect the shaft for tube roundness and yoke alignment. A bent shaft or off-axis yoke will require more correction mass than a straight shaft — and the correction will shift as the shaft flexes at speed, creating a speed-dependent vibration that no static weight can fully correct.

Vehicles showing vibration at 60-80 mph on a freshly rebuilt driveshaft often need corrections in the 0.3-0.6 oz range — the 231546-1 addresses the lower end of that bracket.Cross-reference: Spicer 231546-1. Always run the completed assembly on a balancing machine after welding the correction weight — the welding process itself introduces a small mass change and can shift the correction plane slightly from the calculated position.

This weight is common in primary correction applications on 2.5 and 3-inch driveshaft tubes used in light trucks and vans. A single 0.62 oz weight at the correct angular position typically brings residual imbalance below 0.1 oz — within spec for most highway-speed applications.SKU231546-2Weight0.62 ozSeries231546 (Spicer-compatible)Cross-referenceSpicer 231546-2Placement tip: the angular position from the balancing machine readout is measured from a reference mark on the tube (typically the heaviest point indicator). When the machine calls out “add weight at 165 degrees” — that means 165 degrees from the reference mark in the direction of shaft rotation, not from the imbalance location.

The 231546-3 at 0.98 oz is used when the correction call is close to 1 oz but the next lighter weight (-2 at 0.62 oz) would leave too large a residual.SKUWeight231546-10.43 oz231546-20.62 oz231546-30.98 ozCross-reference: Spicer 231546-3. The 231546 family is distinct from the 231817 and 231536 series — each series has different physical profiles and should not be mixed on the same driveshaft unless the tube geometry permits both profiles to seat flush.

At 0.19 oz, this is a light correction weight used when the balancing machine shows a residual that the lighter -9 would undercorrect but the -2 would overshoot. Having the full 231817 series on hand allows single-weight corrections across a wide range without stacking.SKU: 231817-1Weight: 0.19 ozSeries: 231817 (Spicer-compatible)Position: Between 231817-9 (0.13 oz) and 231817-2 (0.27 oz)Cross-reference: Spicer 231817-1When working on a driveshaft that originally carried a 231817-series weight and the weight is lost or damaged, the balancing machine must be run to determine the replacement mass.

Passenger car rear driveshafts — typically 2.5″ to 3.0″ diameter, running at relatively high RPM — require tighter balance tolerances than truck shafts. The 0.27 oz range often covers the primary correction on these lighter-duty shafts after service.Q: When is 231817-2 the right choice vs. the heavier -4?A: When the balancing machine reads a correction of 0.20-0.35 oz. Using the -4 (0.56 oz) would significantly overcorrect and require a second trim pass — sometimes ending up worse than the original imbalance if the correction angle isn’t precise.Q: Is 231817-2 compatible with the Spicer OEM part?A: Yes.

Rather than stacking a -4 (0.56 oz) and a -9 (0.13 oz), the -6 delivers close to the combined mass in one piece at the exact correction angle. This is particularly relevant on OEM replacement driveshafts where the original weight may have been a single 231817-6.Cross-references: Spicer 231817-6.

The 231817-9 at 0.13 oz is the lightest — a trim weight for final-pass corrections where previous primary weights have brought the residual imbalance close to tolerance but not quite within spec.SKU: 231817-9Weight: 0.13 ozSeries: 231817 (lightest available in series)Cross-reference: Spicer 231817 series balance weightsThe 231817 numbering convention is a Spicer/Dana part family. When working on OEM driveshafts with Spicer-marked weights, use the same series family for replacements to ensure consistent material and profile geometry. Mixing weight series on the same shaft can create minor profile differences that affect how the weight seats against the tube.

The 5006852-2 addresses a single-weight correction in that scenario without requiring multiple lighter weights.Placement on large-diameter tubes: use a protractor or angle-finding balancing fixture to mark the angular position precisely. On a 4-inch diameter tube, a 10-degree angular error on a 1.5 oz weight creates approximately 0.26 oz of residual at 90 degrees to the intended correction plane — still detectable at highway speed.

This occurs on new tube fabrications where tube straightness tolerance is at the edge of specification, or on rebuilt heavy-duty driveshafts where tube replacement disturbed the factory balance. The 5006852-4 is the heaviest individual weight in the 5006852 series.Before welding a correction this large, confirm the source of the imbalance is not a bent tube or loose component. A 3-ounce balance weight can mask — but not correct — a structural issue. If the shaft requires more than 3 oz in a single plane, the tube may need straightening before balancing.SpecValueSKU5006852-4Weight3 oz / ~85 gSeries5006852 (heaviest available)WeldFull perimeter weld required Show less (-) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

When a driveshaft operating in a corrosive environment requires a larger correction mass, the 5010901-11 handles the heavier end of the range where the smaller -6 or -8 would require stacking.Q: Why not just use a carbon steel weight on a stainless tube?A: Galvanic corrosion. Carbon steel in contact with stainless in the presence of an electrolyte (road salt, water) sets up a galvanic cell that accelerates corrosion of the carbon steel weight. This causes the weight to lose mass unpredictably, throwing the shaft back out of balance.Q: What filler metal for welding the 5010901-11 to a carbon steel tube?A: ER309L for TIG or MIG. If welding to a stainless tube, use ER308L or ER316L depending on tube grade.SKU: 5010901-11Material: Stainless SteelProfile: 0.96″ Show less (-) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
