GPM Racing Spring Steel Adjustable Upper & Lower Suspension Links - 20pcs Set for Traxxas 1/10 TRX4 (TRX4160ST)

Precision-engineered spring steel links for TRX4

This 7pcs link set replaces stock tie rods on TRAXXAS TRX4 Trail Crawler models with spring steel components engineered to reduce flex and maintain accurate steering geometry under load. Adjustable reverse-threaded rod ends permit exact toe and wheelbase calibration without axle housing modification.

Designed for scale RC application, the kit supplies midpoint reference measures for setup: front upper 80.5mm, front lower 114.8mm, rear upper 139mm, rear lower 135.5mm. The tie rod diameter is increased from 5mm to 6.5mm to raise system stiffness while keeping installation compatible with stock mounting points.

Specifications

Intended for hobbyists seeking a robust, low-deflection link solution for TRX4 crawlers; fitment follows stock link replacement procedures with attention to midpoint and toe calibration for predictable handling.

How do I verify correct midpoint alignment?

Measure between the specified chassis points and adjust the rod lengths so the front upper reads 80.5mm, front lower 114.8mm, rear upper 139mm and rear lower 135.5mm, then lock rod ends securely.

What torque or thread prep is recommended?

Use conservative torque settings appropriate for small stainless screws and consider a medium thread-lock where threads engage alloy mounts; avoid over-torquing rod ends to preserve thread integrity.

Any tips for tuning steering response?

Start with equal midpoint lengths, then make small incremental adjustments to the front tie rods to alter toe; the stiffer 6.5mm rods will produce crisper inputs compared to stock 5mm links.

Does the kit require axle housing modification?

No axle housing modification is required for fitment; the design uses stock attachment points and provides adjustable lengths to achieve desired geometry. Write Product Review Please sign in your account before you can write any review. Sign In Close
