Front differential ring & pinion upgrade

This GPM aftermarket ring and pinion set is an RC-scale replacement designed for the TRAXXAS UNLIMITED DESERT RACER front differential. The kit swaps the stock gearing for hardened steel #45 components to improve wear resistance and deliver a more consistent gear mesh under load.

Use this set when the original ring or pinion shows wear, or when tuning for heavier duty runs where gear durability and steady power transfer across the front gearbox are priorities. The components are intended for installation inside the front gearbox and include the mounting screws needed for reassembly.

Packing includes

  • Ring Gear - 1pcs
  • Pinion Gear - 1pcs
  • Stainless Steel Flat Head Screw 2.5x10 - 4pcs

Original Name / Part No:

Part location: Inside front gearbox

Will these gears fit directly into the stock front gearbox?

What tools or checks are recommended after installation?

Reassemble the front gearbox per your manual, verify gear mesh and backlash, and ensure screws are snug but not over-tightened to avoid binding.

What benefit does hardened steel #45 provide over stock gears?

Hardened steel #45 increases wear resistance and maintains gear tooth profile under heavier loads, helping keep a more consistent mesh during aggressive use.

Does the set include all screws required for reassembly?

Yes, the package includes four stainless steel flat head screws sized 2.5x10 for the front gearbox reassembly.
