The UMI Performance 78-88 GM G-Body Front 1in and 70-81 F-Body 2-1/2in Lowering Spring is a high-performance coil spring designed to improve vehicle handling and stance. Crafted with precision, these springs are wound from 5160 CrSi premium wire and feature a linear 600 lb/in rate. They are engineered to be stiffer than stock springs, providing increased performance by reducing body roll and lowering the vehicle’s center of gravity. These springs are ideal for enthusiasts seeking enhanced cornering, autocross, and Pro-Tour capabilities, offering a combination of durability and improved handling characteristics.

Suitable for 1978–1988 GM G-Body and 1970–1981 F-Body vehicles, these springs are a direct bolt-on upgrade for front suspension systems. Designed in collaboration with a Sprint Cup chassis engineer, they serve as performance upgrades for street, autocross, and racing applications. Installation involves replacing the stock springs with these lower, stiffer units to achieve a lowered stance and improved stability. The kit includes the specified springs, providing a straightforward upgrade for vehicle enthusiasts aiming for better handling and a more aggressive look.
