UMI Performance SS203049 Shock & Spring Handling Kit Factory Height 1967 GM A-Body

The UMI Performance SS203049 is a complete shock and spring handling kit engineered to deliver a dramatic improvement in handling and cornering control while maintaining factory ride height on 1967 GM A-Body vehicles. This USA-made kit pairs UMI's race-quality coil springs with a nitrogen-charged monotube shock for a well-matched, high-performance suspension system right out of the box.

Key Features:

• Factory height springs with 530 lb/in front rates and 130 lb/in linear rear rate for firm, consistent handling
• Premium CrSi (Chrome Silicon) wire sourced from US suppliers, precision wound for accurate and consistent spring rates
• Nitrogen-charged monotube shock absorbers for improved damping response and outstanding control
• Race-proven shock construction with heavy-duty mounts designed for long-term durability in stock mounting locations
• Medium-firm compression valving combined with a ramped-up rebound curve to precisely control spring movement and reduce body roll
• Complete kit — Made in the USA at UMI's Philipsburg, PA facility

The UMI monotube shocks feature a large-diameter piston and nitrogen charge that dampen road bumps and provide a crisp, responsive feel without a harsh ride. The ramped rebound valving works in tandem with the coil springs to minimize body roll through corners while keeping the ride comfortable for daily driving, Pro-Touring, corner carving, and light drag use.

Engine Weight Note: Springs are rated for small block engines. An additional 1/4" front end drop may occur on vehicles equipped with full-weight big block engines. Lightweight LS swaps may require minor spring trimming.
