Traxxas TRX-4 Front Bumper Mount with Brass Weight and 25T Aluminum Servo Horn - TRX431FX25TS by GPM  [TRX431FX25TS]

Front bumper and servo horn upgrade for TRX-4

This aftermarket set is an RC-scale front bumper mount and steering assembly made for Traxxas TRX-4 trail crawlers. It pairs a brass bumper mount with a 25T aluminum servo horn and a spring steel steering link to deliver a compact solution for front-end stabilization and finer steering adjustment while leaving the stock chassis intact.

The kit is simple in function: the brass mount secures the bumper and adds measurable nose weight for better front traction, the straight-arm 25T aluminum horn gives dual-hole tie-rod tuning for steering geometry, and the spring steel link increases fatigue resistance under load. A complete hardware pack is included to swap or upgrade the original fasteners during fitment.

Made for scale trail tuning, this assembly lets you move the servo slightly forward to shift front center of gravity and trial added nose mass (approx. 200g reported use) and rapid tie-rod geometry changes without major chassis surgery. This is an RC accessory only and is not for real vehicle use.

For TRX-4 owners chasing improved axle weight balance and crisper steering feedback, this GPM front-end kit is a compact, reversible option; confirm screw lengths and check steering throw after fitment to ensure clearance and correct tie-rod geometry.
