TRAXXAS GT4 TEC 2.0 Rear Knuckle Arm Aluminum Upgrade GT022 by GPM  [GT022]

Rear knuckle arm upgrade for GT4 TEC 2.0

This replacement rear knuckle arm is designed as an aftermarket upgrade for TRAXXAS GT4 TEC 2.0 platforms, supplied as a 2pcs set to stabilise the rear CVD shaft, rear arms and the upper rear tie rod so the car holds a more consistent rear geometry. The part is made from aluminum 6061 T6 with Delrin collars pressed into the arm bores to minimise fitment gap and increase joint stiffness under load.

The arm is intended to reduce lateral play at the CVD and upper link mounting points, cutting small deflections that can shift toe and rear track during acceleration and cornering. Replacing worn plastic knuckles with these aluminum arms gives a firmer pivot point and helps make suspension reactions repeatable across a run.

Fitting is straightforward for hobby technicians familiar with the rear hub assembly. The kit contains the two knuckle arms only, so confirm existing screw types and lengths before installation, and recheck alignment and toe after fitment to preserve the desired handling balance.

Use this set to replace fatigued rear knuckles on GT4 TEC 2.0 cars or to stiffen rear pivot points as part of a handling tune; verify hardware compatibility before final assembly.
