UMI Performance 78-88 GM G-Body Spring/Shock Lowering Kit 1in Rear 350lb Lowering Kit

Overview

UMI’s lowering package includes four Viking double adjustable shocks, a hybrid front coil-over spring system with 350 lb front springs, and your choice of 1 or 2-inch UMI rear lowering springs. The 350 lb springs are ideal for small block cruising or drag racing with moderate weight reduction, offering a balanced mix of ride quality and improved performance. The hybrid front coil-over system provides a 0–3" adjustable front drop, while the rear springs allow for either a 1" or 2" drop to fine-tune the vehicle’s stance. Viking’s double adjustable shocks feature 19 compression and 19 rebound settings, enabling quick, tool-free suspension adjustments for street, strip, or improved cornering performance. The kit is completely bolt-in, requiring no welding or front spring compressor, and optional Spanner Wrench and Thrust Bearing Kits make ride height changes even easier. This setup delivers enhanced adjustability and performance while maintaining good street manners, making it a versatile choice for small block applications.
