Traxxas TRX-4 Scale Front Bumper Mount and 25T Aluminium Servo Horn - TRX431FX25TS by GPM  [TRX431FX25TS]

Scale front bumper mount and servo horn for TRX-4

This aftermarket assembly is a purpose-built front bumper mount and steering linkage for Traxxas TRX-4 trail rigs. It pairs a brass bumper mount with a 25T aluminium servo horn and a spring steel tie link to provide front-end stability and more precise steering adjustment without modifying the original chassis rails.

In practice the brass piece stabilises the bumper and introduces front mass for better weight distribution, the 25T aluminium horn supplies a straight-arm, two-hole layout to fine tune tie-rod length, and the spring steel link offers increased longevity under load. A full set of hardware is included to replace the stock fixings when installing the mount and horn.

Designed for scale trail use and tuning sessions, the kit lets you advance the servo slightly forward to test front centre of gravity changes and trial added nose weight (approx. 200g reported use) and quicker tie-rod geometry adjustments without cutting the chassis. This is an RC accessory only and is not for real vehicle use.

For TRX-4 tuners focused on front-end balance and sharper steering feedback, this GPM upgrade is a compact, reversible approach; always confirm screw engagement and steer geometry after installation to avoid binding.
