TRAXXAS XRT 8S 35T Spur & 20T Input Gear Kit XRT3520S by GPM  [XRT3520S]

Reinforced spur and input gear for TRAXXAS XRT 8S vehicles

This aftermarket gear assembly is supplied as a replacement for certain TRAXXAS XRT and X-Maxx 8S platforms. The primary gears are manufactured from 20CrMnTi steel and the kit adds a 7075 aluminum fixed mount plus bearings to create a three-point support, which helps improve transmission stability versus the original two-point setup.

The product integrates a 35T spur gear with an M1.5 module and a 20T transmission input (motor) gear with an M1.0 module into a combined motor-gear and input-shaft configuration that removes the older 2.5mm locating pin. The manufacturer lists a 35T spur with a 6mm D-shaped motor hub opening, 14mm tooth width and an approximate 55.4mm outer diameter, and a 20T motor gear with 1.0 module.

Intended to reduce wear and maintain gear mesh under heavy torque from 8S setups, this kit is not suitable for TRAXXAS 1/5 X-Maxx 8S Monster Truck-77096-4 as noted by the maker.

For modelers running TRAXXAS XRT or X-Maxx 8S rigs, this GPM kit replaces OEM spur and input gears with hardened steel parts and a 7075 mount to deliver better wear resistance and steadier transmission under heavy loads.
