The UMI Performance SS203052 is a complete coil spring and monotube shock lowering kit engineered to drop your vehicle 1 inch while delivering a significant upgrade in handling, cornering stability, and overall ride control. Designed for street cruising, Pro-Touring, corner carving, and light drag applications, this kit pairs race-quality springs with purpose-built monotube shocks for a cohesive, high-performance suspension system.

Key Features:

• 1-inch lowering for improved stance and reduced center of gravity
• 530 lb/in front spring rate and 130 lb/in linear rear spring rate for consistent, predictable handling
• Premium CrSi (Chrome Silicon) wire — USA-sourced and wound to precise rates for long-term performance and durability
• Nitrogen-charged monotube shock absorbers with race-proven construction for superior damping and control
• Medium-firm compression valving for a comfortable yet performance-oriented ride
• Ramped-up rebound valving to properly control spring movement, reduce body roll during cornering, and enhance high-performance driving dynamics
• Complete kit — Made in the USA

Big Block Engine Note: Vehicles equipped with full-weight big block engines may experience an additional ¼-inch front end drop beyond the standard 1-inch lowering.

Whether you're building a Pro-Touring cruiser or a corner-carving muscle car, the UMI Performance SS203052 spring and shock kit provides the high-performance foundation your suspension demands — all backed by UMI's American manufacturing standards.
