The UMI Performance spring and shock kit is designed to lower your car 1 while providing a huge improvement in handling and control. These kits feature our race quality lowering springs which provide a high performance foundation for your ride. Premium US sourced CrSi wire is wound into the correct rates for street cruising, Pro-Touring, corner carving or light drag use. The UMI Performance monotube shock features medium-firm compression valving and a ramped up rebound curve to properly control the UMI spring. The rebound valving also controls body roll when cornering and contributes to a high performance ride.
Springs: Springs intended for small block engine. Lightweight LS may require trimming and an additional 1/4" front end drop may occur with a full weight big block.
