GBF-X – 1978-1988 GM G-Body Shock & Spring Kit, Lowering, Double Adjustable
$1,169.99
PRODUCT DESCRIPTION
UMI's lowering package includes four Viking double adjustable shocks, a hybrid front coil-over spring system, and either 1 or 2-inch Hotchkis rear lowering springs. The kit features increased spring rates for improved handling, allowing you to adjust your car's height and stance for maximum performance and style. The hybrid front coil system offers a 0-3" front drop and is easy to adjust and lock in place. The 1 or 2-inch rear lowering options allow you to either lower the factory height or achieve a Pro-Tour appearance.
The double adjustable Viking shocks provide 19 compression and 19 rebound settings for customization, enabling you to transition from street to strip to corner-carving handling simply by turning the knobs. No tools are needed for adjustment. The kit is bolt-in, requiring no welding, and no spring compressor is needed for the front.
Included in the kit are:
- (2) Front coil-over shocks, double adjustable
- (2) Rear shocks, double adjustable
- (2) Front springs, with a choice of spring rate
- (2) Rear springs, with a choice of rear drop
A Spanner Wrench and Thrust Bearing Kit are recommended for easier height adjustments but are not required for installation. The Thrust Bearing Kit is designed to simplify adjustments between the spring and the spring seat, as the spring seat rotates on a bearing.
Front Spring Rate Options:
- 250 lb: 11" tall springs for drag racing only; requires significant weight reduction
- 350 lb: Suitable for small block cruising or drag racing with weight reduction
- 450 lb: Recommended for small block cruising and big block drag racing
- 550 lb: Ideal for small block handling and all big blocks except for drag racing
Overall, UMI's lowering kit offers advanced adjustability and performance enhancements for your vehicle.
