GPM HSP0222WD Rear knuckle arm for HSP 1/10 Crusher BL 2WD, aluminum rear knuckle arm  [HSP0222WD]

Rear knuckle arm overview

The GPM HSP0222WD rear knuckle arm is an aluminum replacement part designed for the rear suspension of the HSP 1/10 Crusher BL 2WD RTR RC truck family. It replaces the stock rear knuckle to provide a lighter, more rigid mounting point for the rear wheel hubs and the rear upper tie rods.

This knuckle locates the bearing precisely to reduce internal play between hub and axle, and it includes multiple positioning holes so the rear upper tie rods can be fixed at different points to change steering geometry and roll characteristics. The part is adjustable by relocating the tie rod connection, allowing measured tuning of rear toe and steering response without changing other suspension components.

Made from 6061 T6 aluminum, the component balances tensile strength and weight for repeated off-road use. Installation is straightforward for users familiar with basic RC maintenance: remove the hub assembly, swap the knuckle, and secure fasteners to factory torque levels while checking alignment after installation.

Use this knuckle arm when you need a durable, adjustable rear hub mount for tuning rear toe and improving wheel stability on HSP 1/10 Crusher BL 2WD platforms; verify fit and alignment after installation and retighten fasteners after initial runs.
