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

Aluminium knuckle arm overview

This aluminium front/rear knuckle arm set is an aftermarket replacement designed for TRAXXAS E-REVO chassis, supplied as a single pair for left and right positions. The machined aluminium body focuses on reducing steering tolerance and maintaining a precise connection between the steering linkage and wheel hub, which helps preserve consistent geometry under load.

The part is intended for RC-scale use only and is compatible where TRAXXAS E-REVO style knuckle arms are accepted. Installation follows the same mounting points as the stock plastic parts; reuse factory hardware where applicable and confirm clearance for hex dust caps and dust-proof caps. The kit fit is described as tight with low play, delivering crisper steering feedback during tuning and setup adjustments.

The package also includes small service items for installation: Delrin screws and multiple dust caps plus O-rings to help retain seals around pivot points during typical off-road operation.

Use these knuckle arms when you need a low-tolerance, durable alternative to stock plastic pieces for improved steering precision and predictable handling during tuning sessions.
