Description

The UMI Performance spring and shock kit is designed to lower your car by 1\" while enhancing handling and control. These kits include race-quality lowering springs made from premium US-sourced CrSi wire, custom-wound for optimal performance in various driving conditions such as street cruising, Pro-Touring, corner carving, or light drag racing. The Bilstein gas-charged shocks in the kit provide a blend of comfort and control, offering a great driving experience. Please note that the springs are designed for small block engines, and lightweight LS engines may require trimming. Additionally, a slight 1/4\" front end drop may occur with a full weight big block. The front springs have 600 lb/in rates and 130 lb/in linear rate, ensuring optimal performance and durability. Trust in UMI Performance for quality products that deliver on performance and reliability.
