GPM TRAXXAS MAXX Front Differential Helical Bevel Upgrade TXMS1337TS - Upgrade Part  [TXMS1337TS]

Durable helical bevel and pinion set

This is an aftermarket helical bevel and pinion kit for the TRAXXAS MAXX front differential, identified by model TXMS1337TS. Helical spiral teeth provide smoother engagement and more even load spread inside the diff case than straight bevel teeth.

Forged from high carbon steel, the gears are designed to resist wear and lower the chance of tooth failure when compared with stock plastic bevels. The pair retains the factory effective gearing relationship referenced in service notes, such as the 37T/13T equivalent, while replacing plastic parts with metal counterparts.

The intended fitment is inside the front differential case where the larger bevel gear meshes with the pinion. The set contains one large helical bevel and one small helical pinion, 2 pcs total, matched to original geometry so no ratio change is needed for fitment.

When installed as a replacement or during a strength upgrade, these metal gears help improve internal power transfer smoothness and reduce deformation under stress. They are suited to hobby use where stronger front differential gearing is preferred on TRAXXAS MAXX platforms.

As a drop-in metal replacement for TRAXXAS MAXX front bevels, this GPM helical gear set offers a clear upgrade for durability and smoother internal gearing while maintaining the stock ratio.
