Technical overview of WR022X rear knuckles

The WR022X set comprises six brass rear knuckle arms designed as an aftermarket replacement for AXIAL WRAITH chassis. These brass knuckles locate on the rear axle to provide a secure mount and concentrated mass where tuning rear traction and balance is commonly performed.

Installation procedure replaces the stock plastic or alloy knuckles with the brass set and uses the supplied fasteners for secure attachment. The kit contains stainless steel round head screws (3x8) in a quantity of 4pcs for the mounting points that require those screws. Adhere to the chassis service instructions for rear hub and axle removal and reassembly to avoid interference with driveshafts or suspension components.

Tuning guidance: adding brass mass at the rear knuckles will shift mass distribution on the model, which can increase rear traction on loose terrain or during climbs and may modify steering response. Implement weight changes incrementally and verify clearance with the motor, driveshafts, and full suspension travel after installation.

Introduce the brass knuckles as part of an incremental tuning plan; record handling before and after the change and test on representative terrain to assess traction and steering balance.
