TRAXXAS TRX4 Front and Rear Brass Axle Mounts TRX4089X by GPM  [TRX4089X]

Brass axle mount upgrade for TRX4

This brass axle mount kit is intended for TRAXXAS TRX4 Trail Crawler models to secure suspension links and damper pickups on both the front and rear axles. Using brass offers strong mounting points and axle ballast to influence slow-speed handling and traction on technical sections.

The set includes four brass mounts and the necessary stainless steel flat head screws, and each mount offers several threaded hole options so you can vary link geometry. The supplied 2.5x10 flat head screws thread into the available holes to lock link positions, making it quick to shift suspension link height and damper placement without altering the axle housings.

Fit the mount to the axle, line up the suspension link and damper pickup points, then secure with the flat head screws through your chosen threaded holes. Different hole choices change the effective link length and damper angle, which helps with tuning roll center, articulation, and axle weight distribution for trail performance.

For trail builders who want a straightforward, durable upgrade to change suspension geometry and add axle ballast, this brass mount set makes tuning faster and more predictable.
