HSP 1/10 Crusher BL 2WD Aluminium Rear Knuckle Arm HSP0222WD performance upgrade by GPM  [HSP0222WD]

Knuckle arm introduction

The HSP0222WD rear knuckle arm is an aluminium aftermarket part for the rear suspension of HSP 1/10 Crusher BL 2WD RTR trucks. It replaces the stock knuckle to give a more rigid mounting point for the rear wheel hub and upper tie rod.

The design locates the bearing to cut down play between hub and axle and includes several positioning holes so the rear upper tie rods can be attached at different points to change toe and roll characteristics. Switching the tie rod connection point allows measured tuning of rear toe and steering response without modifying shocks or other suspension joints.

Manufactured from 6061 T6 aluminum, the component balances strength and weight for durable off-road performance. Fitting is straightforward for anyone familiar with basic RC work: remove the hub assembly, fit the replacement knuckle and tighten fasteners to factory torque ratings, then verify alignment after the first outing.

Use this knuckle arm to strengthen the rear hub mounting and gain adjustable tie rod geometry for better stability and handling on HSP 1/10 Crusher BL 2WD vehicles; always check fit and retighten fasteners after running.
