SUMO Rear Subframe Mount Bushing Insert Kit

Positive Traction Kit – Locks Subframe to Body

The SUMO Rear Subframe Mount Bushing Insert Kit is designed as an easy-to-install solution for reducing rear crossmember movement. Instead of replacing the factory bushings, this insert system works with the originals to eliminate excess compliance — often referred to in motorsport as “lost motion.”
