This GPM aluminum rear knuckle arm is built to sharpen the handling of the HSP 1/10 Crusher BL 2WD by delivering rigid support for the rear axle and upper tie rods. Constructed from Aluminum 6061 T6, it keeps weight in check while offering durable service life. Accurately located bearing seats reduce play for smoother rotation and the range of tie rod holes allows quick adjustment of steering geometry for different surfaces.
A sensible upgrade for drivers seeking tighter rear-end control and the ability to tune steering feel for varied track or trail conditions.
