Precision aluminium rear knuckle arm engineered for rear geometry control

The GPM Aluminum Rear Knuckle Arm is crafted to enhance rear-end rigidity and repeatable steering geometry on the HSP 1/10 Crusher BL 2WD. Using Aluminum 6061 T6, the component is designed to deliver a high stiffness to weight ratio while providing accurate bearing seats that reduce axial play and promote consistent wheel rotation. Multiple tie rod mounting positions permit fine adjustments to toe and roll behaviour to suit tuning or racing setups.

Packing includes

  • Rear knuckle arm - 2pcs

Original Name / Part No:

A precision upgrade for hobbyists focused on durable, repeatable handling improvements and straightforward tuning of rear steering geometry.

How does the knuckle arm maintain bearing alignment?

Tight tolerance bearing seats on the aluminium arm help keep bearings concentric to the axle, reducing runout and maintaining consistent rotation under load.

What tuning range is possible with the multiple tie rod holes?

The available mounting positions allow changes to effective steering link angle and roll centre, giving a practical range for handling refinement without additional parts.

Are there recommended checks after fitting this part?

Verify bearing seating, confirm free wheel rotation, and test link geometry on a short run to ensure no binding and expected steering response.
