This pair of coil perches and retainers specifically locates rear coil springs to offer an easy swap when used in a factory location with the modular trusses. They are clockable to all angles to offer you larger lifts, while the CNC laser is cut and bent from 1/4 inch steel. This pair includes tubing spacers, bottom perches, flat tube caps, ½ inch retainer hardware and spring retainers for both axle sides.
