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

Rear knuckle arm for GT4 TEC 2.0

This RC-scale rear knuckle arm is produced as an aftermarket replacement for TRAXXAS GT4 TEC 2.0 platforms, supplied as a 2pcs set and intended to stabilise the rear CVD shaft, rear arms and the rear upper tie rod to help the car maintain balanced handling. Construction uses aluminum 6061 T6 with Delrin collars inserted into the arm bores to reduce fitment gap and improve joint stiffness for more consistent geometry under load.

The component's role in setup and tuning is deliberate and specific: by tightening the interface around the CVD and upper rod locations the assembly reduces lateral play and small deflections that can upset toe and rear track under acceleration or in corners. When replacing worn plastic pieces, the aluminum arms provide a firmer pivot point that can make suspension responses more repeatable across a run.

Installation is straightforward for familiar hobby technicians, the part installs in the rear hub area as the knuckle arm assembly. Verify existing screw types and lengths before fitting since the package lists the arms only, and check alignment and toe after installation to ensure the desired handling balance is maintained.

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