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

Front-end bumper mount and steering horn for TRX-4

This aftermarket assembly is a scale front bumper mount and steering package for Traxxas TRX-4 crawlers. It merges a brass bumper mount with a 25T aluminium servo horn and a spring steel steering link to provide added front mass and finer steering adjustment while keeping the factory chassis unchanged.

The brass mount stabilises the bumper and introduces front ballast for improved weight distribution, the 25T aluminium horn offers a straight-arm, two-position tie-rod setup for quick geometry tuning, and the spring steel link raises service life under load. A full hardware set is supplied to swap or upgrade the original fixings when installing the parts.

Suited to scale trail running and incremental tuning, the kit lets you set the servo forward to shift front centre of gravity and trial added nose weight (approx. 200g reported use) and fast tie-rod changes without extensive chassis alteration. This is an RC accessory only and is not for real vehicle use.

For TRX-4 drivers prioritising front axle balance and sharper steering feedback, this GPM mount and horn provide a compact, reversible tuning route; check fastener engagement and steering geometry after fitment to confirm clearance.
