UMI Performance 78-88 GM G-Body Lowering Spring Front 2in Lowering - 3051F

The UMI Performance 78-88 GM G-Body Lowering Spring Front 2in Lowering (P/N 3051F) is a direct-fit front spring built specifically for 1978-1988 GM G-Body chassis owners who want a lower stance without sacrificing a usable, controlled ride. Engineered with a linear 600 lb/in front spring rate, this UMI performance spring drops the front end two inches while keeping the suspension planted through corners, making it a popular choice for autocross, Pro-Touring, and corner-carving builds as well as street cruisers looking to clean up excess wheel gap.
