AXIAL WRAITH Brass rear knuckle arms 6pcs by GPM WR022X  [WR022X]

Brass rear knuckle arms for WRAITH

This GPM WR022X brass rear knuckle arm set is an aftermarket RC-scale replacement designed for AXIAL WRAITH platforms. The kit provides six brass knuckle arms that mount to the rear axle area to secure the axle and add measured mass where hobbyists often tune rear traction and balance.

On installation, the brass knuckles replace the standard plastic or alloy pieces and are secured using the included fasteners. The package includes stainless steel round head screws (3x8) in a quantity of 4pcs for mounting points that require those fixings. Follow your chassis manual for disassembly of the rear hub and axle before fitting the brass arms to avoid interference with existing suspension or driveshaft components.

Tuning note: adding brass weight at the rear knuckles shifts mass distribution on the RC-scale model, which can increase rear grip on loose surfaces or during climbs, and may alter steering response. Use these parts as part of an incremental tuning process and verify clearance with the motor, driveshafts, and suspension travel after installation.

The GPM WR022X brass rear knuckle arms are intended for hobbyists seeking a simple, durable aftermarket option to add rear-end weight and a more robust mounting point on compatible AXIAL platforms.
