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

Technical summary of rear knuckle arm

The HSP0222WD rear knuckle arm is an aluminium replacement engineered for the rear suspension of HSP 1/10 Crusher BL 2WD RTR vehicles. It replaces the original rear knuckle to provide a more rigid and accurately located mounting point for the rear hub and upper tie rod.

The component locates the bearing to minimise internal play between hub and axle, and it includes multiple mounting holes that allow the rear upper tie rods to be fixed at alternate positions to adjust steering geometry and roll characteristics. Changing the tie rod connection point enables controlled tuning of rear toe and steering response without altering other suspension components.

Manufactured from 6061 T6 aluminum, the part balances structural strength with reduced mass for repeated off-road use. Installation requires standard RC maintenance steps: remove the hub assembly, install the replacement knuckle and secure fasteners to factory torque values, then verify alignment and retorque after initial operation.

Use this knuckle arm to achieve a precise rear hub location and tunable tie rod geometry for HSP 1/10 Crusher BL 2WD platforms; confirm fit and alignment after installation and retorque hardware as required.
