TRAXXAS GT4 TEC 2.0 Aluminium Rear Knuckle Arm Stiffened GT022 by GPM  [GT022]

Replacement rear knuckle arm for GT4 TEC 2.0

This aftermarket rear knuckle arm set is built for TRAXXAS GT4 TEC 2.0 platforms and supplied as two pieces to stabilise the rear CVD shaft, rear arms and upper rear tie rod so the car holds a steadier rear geometry. The arms are manufactured from aluminum 6061 T6 with Delrin collars inserted into the bores to reduce clearance and raise joint stiffness under load.

The part purposefully tightens the interface around the CVD and upper rod locations to reduce lateral play and small deflections that can upset toe and rear track under acceleration or corner entry. Replacing aged plastic components with these aluminium arms gives a firmer pivot point and helps suspension behaviour remain repeatable across a session.

Fitting is straightforward for those comfortable working on rear hubs; the arms install as the knuckle assembly in the rear hub area. Confirm screw types and lengths before fitting as the set includes arms only, and recheck alignment and toe after installation to keep the handling balance you want.

Use this pair to replace worn rear knuckles on GT4 TEC 2.0 cars or as a simple upgrade to stiffen rear pivot points; check hardware compatibility before final assembly.
