TRX4 Compatible 23T Aluminum Servo Horn with Spring and 4 Hole Positions TRX4023TA/4 TRX4023TA/4H by GPM  [TRX4023TA/4H]

Machined 23T servo horn for TRX4 rigs

This aftermarket arm suits TRAXXAS TRX4 style vehicles and is intended to tighten steering feel while adding a spring-based buffer between the servo output spline and the horn. Fabricated from 6061 T6 aluminum, the straight-arm form improves stiffness without excessive mass.

Functionally the coil spring helps absorb sudden loads to protect the steering assembly, while the quartet of positioning holes gives lateral tie-rod options for adjusting steering ratio and roll centre. Note that the extra thickness around the spring may interfere in the factory servo bay; some TRX4 setups require flipping the support tie rods to clear the horn.

Included in the supply are the servo horn, stainless mounting screws, an aluminum collar and a 3mm washer to assist with installation. Use the hole positions to refine toe and steering response, and double check clearances before final torque up.
