HSP 1/10 Crusher BL 2WD Rear Hub Knuckle HSP0222WD aluminium upgrade by GPM  [HSP0222WD]

Overview of rear knuckle arm

The HSP0222WD rear knuckle arm is an aluminium replacement tailored for the rear suspension on HSP 1/10 Crusher BL 2WD RTR models. It replaces the original rear knuckle to offer a firmer mount for the rear wheel hub and the upper tie rod.

The part locates the bearing accurately to reduce play between hub and axle, and it provides multiple mounting holes so the rear upper tie rods can be secured in different positions to alter steering geometry and roll response. Repositioning the tie rod connection allows tuning of rear toe and steering behaviour without changing other suspension parts.

Made from 6061 T6 aluminum, the component presents a strong yet lightweight option for off-road use. Installation is straightforward for experienced hobbyists: remove the hub, fit the new knuckle and tighten fasteners to the recommended torque, then check alignment after the first test runs.

Fit this knuckle arm to achieve a tougher rear hub mount and finer toe adjustment on HSP 1/10 Crusher BL 2WD vehicles; verify fit and retighten fasteners after initial use.
