Traxxas TRX-4 Brass Front & Rear Link Axle Mounts, Compatible with TRX-4 - JR-TRX424 by Jazrider  [JR-TRX424]

Heavy brass axle link seats for TRX-4 crawlers

The JR-TRX424 set provides brass front and rear suspension link mounts created as a like-for-like replacement for Traxxas TRX-4 axle link seats. The text focuses on the material benefits, intended use in scale crawling, and the role these mounts play in setup and tuning without modifying electronics.

These components present a metal alternative to factory plastic seats, adding weight at the axle and offering a firmer anchor for link ends. Use them when you want to stabilise link mounting and refine suspension geometry incrementally during testing.

Fitment notes: removal of the original plastic seats is usually required, followed by positioning the brass mounts on the axle housing and securing with compatible fasteners. Always confirm thread compatibility and torque settings, then perform a short verification run to ensure alignment and steering response are correct.

For TRX-4 operators aiming to add durable, axle-mounted link seats for scale crawling and more predictable setup changes, the JR-TRX424 brass set is a practical upgrade option that preserves original mounting geometry.
