UMI Performance
UMI Performance 1964-1966 GM A-Body Factory Height Rear Springs (130 lb/in) - 4048R
$189.99
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1964-1966 Buick Skylark and Special, Chevrolet Chevelle and El Camino, Oldsmobile 442, Cutlass, and F85, and Pontiac GTO and LeMans.
UMI Performance engineered these rear springs to deliver modern handling and a crisp, responsive ride while maintaining your vehicle's factory muscle car stance. Designed in conjunction with a leading chassis engineer, these springs eliminate the disconnected "floating" sensation common in stock A-body suspensions, providing the stability needed for autocross, Pro-Touring, and spirited street cruising.
These springs utilize a linear 130 lb/in rate, ensuring predictable suspension behavior and consistent weight transfer during cornering. Each spring is wound from premium 9254 Chromium Silicon (CrSi) wire to prevent sagging and ensure long-term durability under performance driving conditions.
- Spring Rate: 130 lb/in linear rate
- Ride Height: Maintains factory stock height
- Material: Cold-wound 9254 CrSi premium wire
- Finish: Durable black powder coat
- Application: Ideal for Autocross, Pro-Touring, and performance street use
- Manufacturing: Made in the USA
- Part Number: 4048R
