Axial Racing EXO Alloy Rear Knuckle Arm by GPM EX022  [EX022]

Rear knuckle arm for EXO

This alloy rear knuckle arm is an RC-scale replacement part produced by GPM for the Axial Racing EXO platform, supplied as a 1pr set. It serves as a direct spare or hop-up for the rear steering/drive knuckle area, offering an alternative to stock plastic components where a metal item is preferred for durability and dimensional stability under load.

The part's role in a build is specific: it locates the wheel hub, supports the axle or drive stub, and interfaces with suspension links and wheel hex. As a tuning item it can affect wheel alignment tolerances and long-term wear characteristics of nearby suspension and drive components. Installers should check fit against the EXO hub, pin positions, and wheel hex clearance before committing to a full swap.

Because this listing is an aftermarket RC accessory for the Axial EXO chassis, compatibility is focused on EXO platform configurations. The product is sold as one pair, suitable for replacing both left and right rear knuckles on compatible EXO builds.
