TRAXXAS E-REVO Aluminium Front/Rear Knuckle Arms ER021 by GPM  [ER021]

Precision aluminium knuckle overview

This aluminium front and rear knuckle arm set is an aftermarket replacement for TRAXXAS E-REVO chassis and ships as one matching left and right pair. The machined aluminium body is made to cut steering tolerance and keep a solid link between the steering linkage and wheel hub, helping geometry remain consistent under load.

The component is intended for scale RC use and fits applications that accept TRAXXAS E-REVO style knuckles. Installation uses the same mounting points as the original plastic parts; reuse the factory hardware where suitable and check clearance for hex dust caps and dust-proof covers. The kit fit is tight with minimal play, producing sharper steering feedback during setup and tuning.

The package includes small service items to assist installation: Delrin screws, multiple dust caps and O-rings to help retain seals around pivot points during routine off-road running.

Choose these knuckle arms when you want a durable, low-tolerance alternative to stock plastic pieces for more predictable steering and easier suspension tuning.
