XRAY aluminium pins built for hot-running differentials

The XRAY 355087 Aluminum Differential Pin Set is a lightweight upgrade for the internals of large center differentials, engineered to work with the internal satellite gears of models like #355013. Machined from polished aluminium and fitted with steel inserts, these pins are aimed at extending service life while cutting rotating mass.

Performance gains from reduced mass

Switching to aluminium pins lowers weight by about 30% compared to steel, reducing inertia inside the differential. That weight saving helps the drivetrain react more quickly and keeps handling consistent during extended events.

Built-in reinforcement for longevity

Steel inserts are used where load is concentrated, giving the pins improved wear resistance versus pure aluminium parts. This construction helps keep tolerances stable when the diff sees elevated temperatures.

Specifications

  • Material: Precision-ground polished aluminum
  • Size: 3.5 x 33 mm
  • Compatibility: Large center differential #355013
  • Weight Reduction: 30% lighter than steel pins
  • Includes: Set of 2 pins with steel inserts

A practical component upgrade for racers and hobbyists who want to reduce internal mass while retaining reinforced contact areas in their diffs, the XRAY 355087 is straightforward to fit and maintain.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Do the XRAY 355087 pins require shims or spacers?

These pins are made to the specified 3.5 x 33 mm size and normally install without extra shims. Always verify fitment against your differential case and satellite gears before final assembly.

Can I use them on sealed diffs?

If the sealed unit uses the same internal satellite setup and pin dimensions as large center differential #355013, the pins will fit. Check internal clearances and sealing arrangements first.

What grease should I use with these pins?

Choose a diff grease suited to your track temperatures and driving style. Proper lubrication helps the steel inserts and aluminium body work together without accelerating wear.
