TRAXXAS XRT 8S Reinforced Front & Rear Diffs and Upper Bulkhead XRT1213KIT by GPM  [XRT1213KIT]

Durable Front/Rear Diff and Upper Bulkhead Assembly

This aftermarket kit is designed to replace the stock front and rear differential assemblies and upper bulkheads on TRAXXAS XRT 8S platforms. Differential bevels and pinions are produced from heat-treated 4140 carbon steel for improved strength and wear life. Housings and upper bulkheads are CNC machined from 7075-T6 aluminum to increase chassis stiffness where it matters while keeping weight reasonable. The kit targets heavy-duty RC use-cases and is intended to provide a tougher, more predictable drivetrain under sustained stress.

Spec highlights include a 32T bevel gear, 10T pinion gears, and module M1.6 component specification. Bearings and gaskets required for the assembled differentials are included to allow direct replacement of the factory parts. The alloy housings and hardened steel gears redistribute loads away from factory plastic components to reduce wear and improve long-term reliability.

This kit is a practical upgrade for UK hobbyists who want increased drivetrain robustness on 1/5 and 1/6 TRAXXAS platforms while keeping installation and tuning straightforward.
