TRAXXAS MAXX Front Differential High Carbon Steel Bevel & Pinion Gears by GPM TXMS1337TS  [TXMS1337TS]

Helical differential gear set

This is a helical bevel and pinion gear set designed for the TRAXXAS MAXX scale monster truck front differential, offered as an aftermarket replacement by GPM (TXMS1337TS). The set uses helical spiral cut teeth rather than straight bevel teeth to provide smoother meshing and more uniform load distribution inside the differential case.

The gears are manufactured from high carbon steel to increase wear resistance and reduce the risk of tooth failure compared with stock plastic bevel gears. The pair maintains the factory gear ratio, preserving the original 37T/13T effective gearing relationship while replacing the stock materials with metal components.

Intended installation location is inside the front differential case, where the large bevel meshes with the pinion inside the differential assembly. The set includes one large helical bevel gear and one small helical pinion gear, 2 pcs total, sized to match the original geometry so no ratio changes are required for basic fitment.

When used as a replacement or during a durability upgrade, these gears primarily improve internal power transfer smoothness and reduce deformation under load compared with plastic bevels. They are suitable for hobby use where stronger metal gearing is preferred in the front differential of TRAXXAS MAXX platforms.

As a direct-fit metal replacement for the TRAXXAS MAXX front differential bevels, this GPM helical gear set offers a straightforward upgrade path for improved durability and smoother internal gearing while keeping the stock gear ratio.
