63-66 Coilover Backhalf - 120-5600-BH-CO **This product will have a lead time; please call to verify expected wait** This Coilover Backhalf kit was created for 1963-1966 Chevy & GMC trucks to replace the factory rear frame and suspension with a fully engineered 4-link coilover system. Perfect for those who want aggressive ride height with improved handling, without air ride complexity. With the updated coilover geometry, it delivers the adjustability and structural integrity needed for refined handling characteristics across both aesthetic and performance applications. The rear suspension has been repositioned inboard to allow clearance for wide wheel setups up to 24” x 15”, while maintaining proper suspension travel and drivability. Adjustable coilover mounts provide a 4"-8" frame height range, allowing the chassis to be set low and dialed in for stance, handling, or competition use.
