The GPM Aluminum Rear Knuckle Arm helps improve the rear-end response of the HSP 1/10 Crusher BL 2WD by providing solid support for the axle and upper tie rods. Machined from Aluminum 6061 T6, it offers a reliable combination of stiffness and low mass. Close tolerance bearing positions reduce play for consistent wheel spin, and multiple tie rod holes make it easy to tune steering characteristics for dirt or hardpack surfaces.
Well suited for weekend racers and backyard bashers who want a durable, tunable rear steering control upgrade.
