Rear axle ring and pinion assembly

This three-piece aftermarket differential gear set upgrades TRAXXAS MAXX rear differentials by replacing the factory rear ring and pinion with hardened steel #45 parts and supplying a stainless steel retention pin.

The hardened #45 components raise wear resistance under repeated impact and the finer tolerances limit backlash so torque transfer is steadier and driveline shocks are reduced. That improved consistency matters when selecting diff oils or setting preload.

Fitment advice: disassemble the differential case following your maintenance routine, install the ring and pinion, confirm the retaining pin sits square and endplay is correct, then check gear mesh through manual rotation before reassembling. Use recommended threadlocker or retainers where appropriate.

Packing includes

  • Ring Gear - 1pcs
  • Pinion Gear - 1pcs
  • Stainless Steel Pin 2.5x13 - 1pcs

Can I run these gears with my stock bearings?

In most cases stock bearings will work, but inspect them for play and replace worn bearings to ensure proper pinion depth and ring support.

Will these gears change final drive ratio?

This is a direct replacement set that preserves the original tooth counts and overall gear ratio; only mesh feel and durability are affected.

How do I check backlash after install?

Set the pinion depth, tighten the case, then measure play by holding the ring and rotating pinion slightly; adjust until there is a small, consistent backlash across the mesh.
