UMI Performance SS203053 Coil Spring & Monotube Shock Handling Kit 2" Drop

The UMI Performance SS203053 is a complete coil spring and monotube shock handling kit engineered to lower your vehicle approximately 2 inches while delivering a dramatic improvement in handling, control, and overall ride quality. Designed for street cruising, Pro-Touring, corner carving, and light drag use, this kit is Made in the USA and built to race-proven standards.

At the heart of this kit are UMI's race-quality lowering springs, wound from premium US-sourced Chrome Silicon (CrSi) wire for superior strength and durability. The springs are rated at 530 lb/in at the front and a 130 lb/in linear rate at the rear, providing a high-performance foundation tuned for both comfort and spirited driving.

The included nitrogen-charged monotube shocks feature medium-firm compression valving paired with a ramped-up rebound curve specifically calibrated to work in concert with the UMI springs. This rebound tuning actively controls body roll during cornering while contributing to a composed, high-performance ride feel.
