UMI Performance SS103049 Coil Spring & Shock Lowering Kit 530 lb/in Front Rate

The UMI Performance SS103049 Spring and Shock Kit is engineered for drivers who demand improved handling and control without sacrificing the classic factory stance. This complete kit pairs race-quality coil springs with high-performance monotube shocks to deliver a Pro-Touring-ready setup straight out of the box.

Key Features:

• 530 lb/in front spring rate and 130 lb/in linear rear rate — precision-tuned for street cruising, Pro-Touring, corner carving, and light drag use
• Premium CrSi (Chrome Silicon) wire sourced from the USA, wound to exact specifications for long-lasting performance and consistent spring rates
• Nitrogen-charged monotube shock absorbers for fade-free, consistent damping under demanding conditions
• Medium-firm compression valving balances everyday comfort with performance-oriented control
• Ramped-up rebound valving precisely controls spring motion, reduces body roll during cornering, and contributes to a high-performance ride feel
• Race-proven shock construction built for long-term durability on street and track
• Designed to maintain factory ride height while dramatically improving handling dynamics

Big Block Engine Note: Vehicles equipped with a full-weight big block engine may experience an additional approximate 1/4" drop in front ride height due to the added mass.

Whether you're building a street cruiser or a serious Pro-Touring machine, the UMI Performance SS103049 kit provides a high-performance foundation with race-quality components and street-friendly manners.
