Supplied as a 1pr set, this alloy rear knuckle arm is built to fit the HPI Bullet 3.0 MT and ST platforms as a straightforward replacement. It replicates the factory rear knuckle mounting and is aimed at users wanting a metal alternative to the standard part.
Replace damaged knuckles or use them when modifying rear-end geometry for handling changes. The component secures wheel hubs and steering links without changing the chassis layout. Typical RC tools and basic alignment know-how are sufficient for fitting.
A practical alloy replacement for Bullet 3.0 rear steering, suitable for maintenance swaps or modest setup tuning at the rear axle.
