TRAXXAS TRX4 Adjustable Brass Axle Mounts TRX4089X by GPM  [TRX4089X]

Brass link mounts for TRX4 platforms

This brass axle mount set is designed for the TRAXXAS TRX4 Trail Crawler family to secure suspension links and damper pick-ups on both axles. The brass material improves longevity and adds axle weight to influence balance and traction during slow-speed trail runs.

The kit includes four mounts plus the stainless steel flat head screws needed for fitting, with each mount offering several threaded holes so you can alter link geometry. The supplied 2.5x10 flat head screws pass through the three threaded locations to lock link positions, enabling quick setup changes for link height and damper placement without cutting or drilling the axle housing.

Fitting is straightforward: position the mount against the axle tube, align link and damper pickup points, then secure with the flat head screws in the selected holes. Changing screw positions adjusts effective link length and damper angle, useful when tuning roll center, articulation, and weight distribution for specific trail conditions.

For hobbyists who want durable, repeatable link mounting and a simple way to alter axle ballast, this brass mount set is a practical tuning part for TRX4 crawlers.
