Description

IMPORTANT NOTICE: Fits with Detroit Speed reverse-eye springs only. Will not fit Crew Cab models. Fits RWD models only.

Detroit Speed offers leaf spring mounts for a variety of applications, including many Chevrolet and GMC trucks from 1982 and up. These leaf spring mounts are required when running Detroit Speed reverse eye leaf springs. They provide additional clearance around the front spring eye and move the mounting hole closer to the frame. This geometry change increases anti-squat for improved traction under acceleration, making it ideal for performance-driven builds. While the factory mount can be modified to clear the reverse eye, this bolt-on solution offers a cleaner install and optimized geometry right out of the box. No cutting or fabrication required.
