1963-1982 Performance Suspension Kits
Designed for more responsive handling, our Performance Suspension Kit is a step above the the famous F-41 option. This kit uses a Composite Monospring and Poly Adjustable Strut Rods at the rear, stiffer (550#) coil springs in the front and Bilstein gas shocks to provide the right amount of dampening at all four corners.

The Advantages of a Composite Monospring
Composite monosprings are the ultimate replacement for aging multi-leaf steel springs and coils. Composed of unidirectional fibers bonded with a special epoxy matrix, they ride better, react faster and last longer than conventional steel springs. By its nature, the fiberglass spring is more elastic than steel. And because of its one-piece design, as opposed to the steel spring’s multi- layered design, the fiberglass spring will not fatigue like the steel spring.

Note: All 1963-82 Suspension Kits contain oversized packages and require additional freight charges. Please ask your sales representative for details.  Note eligible for any discount codes.
