UMI Performance SS103051 Coil Spring & Shock Lowering Kit 2-Inch Drop

The UMI Performance SS103051 Spring and Shock Kit is engineered to lower your vehicle 2 inches while delivering a significant improvement in handling, control, and overall ride quality. Designed for street cruising, Pro-Touring, corner carving, and light drag use, this complete kit combines race-quality lowering springs with high-performance monotube shocks — all Made in the USA.

The lowering springs are wound from premium US-sourced Chrome Silicon (CrSi) wire, providing the ideal spring rates for a balanced blend of comfort and performance. The front springs are rated at 530 lb/in, while the rear springs feature a 130 lb/in linear rate, delivering a predictable and controlled ride feel across a wide range of driving conditions.

The included nitrogen-charged monotube shocks feature race-proven construction for long-term durability. Comfortable yet performance-oriented compression valving works in tandem with a ramped-up rebound curve to properly control the UMI springs, manage body roll during cornering, and contribute to a high-performance driving experience.
