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

Rear hub knuckle summary

The HSP0222WD rear knuckle arm is an aluminium replacement part made for the rear suspension of HSP 1/10 Crusher BL 2WD RTR trucks. It swaps the stock rear knuckle to provide a lighter, stiffer mounting point for the rear wheel hub and the rear upper tie rod.

This knuckle locates the bearing to reduce play between the hub and axle, and it features multiple positioning holes so the rear upper tie rods can be fixed at different points to change steering geometry and roll behaviour. Relocating the tie rod connection allows precise tuning of rear toe and steering response without altering other suspension parts.

Constructed from 6061 T6 aluminum, the item balances tensile strength and mass for repeated off-road use. Installation is straightforward for anyone familiar with basic RC maintenance: remove the hub assembly, swap in the replacement knuckle, torque fasteners to factory values and recheck alignment after initial runs.

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