Thermal-ready diff pins from XRAY for serious RC setups

The XRAY 355087 Aluminum Differential Pin Set improves the operation of large center differentials by replacing heavier pins with precision-ground polished aluminum. These pins fit the internal satellite gears used in large center differentials such as model #355013 and incorporate steel inserts to resist wear under higher operating temperatures.

Lightweight design for smoother drivetrain response

At roughly 30% lower mass than equivalent steel pins, the aluminum pins reduce rotating inertia inside the differential. The lighter components help the drivetrain respond more quickly and maintain consistent behaviour during long runs and high-load conditions.

Steel inserts for added reliability

The aluminum pins include steel inserts where the load is concentrated, providing extra reinforcement compared to pins mounted directly in the case. This hybrid approach balances low mass with improved durability in heat-prone environments.

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 upgrade for hobbyists who want lighter internals and improved wear resistance in demanding conditions, the XRAY 355087 combines aluminium weight savings with steel reinforcement.
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.

How hard is the swap to XRAY 355087 pins?

Removal of the stock pins and installation of the XRAY 355087 set is straightforward for anyone comfortable with differential disassembly. Basic hand tools and clean grease application are recommended.

Will these pins affect diff setup or tuning?

The reduced mass can make the differential feel slightly more responsive. Tuning settings rarely need major change, but check diff oil and rebuild tolerances after fitting the new pins.

Do I need special grease for high-temperature use?

Use a quality diff grease rated for your operating temperatures. The steel inserts improve wear resistance, but proper lubrication remains essential to longevity.
