UMI Performance 6400 Chevy/GMC Shock Absorber

The UMI 6400 lowering kit gives your squarebody truck a 4.5' drop in the front and a 6' drop in the rear, all without breaking the bank. This kit features satin black powder coated 2.5' drop spindles, UMI 2' lowering springs, and a UMI rear flip kit. With no frame notch required, installation is a breeze. For even better performance, consider adding UMI shocks and sway bars. Check out the image below for a glimpse of the lowered stance.\nDesigned specifically for the 1973-1980 GM C10 trucks, these spindles fit perfectly with 1-1/4" brake rotors. If you own a 1981-1987 model, you might find that it comes with 1" brake rotors. In such cases, you'll need to upgrade to the 1-1/4" rotors used on the earlier models to ensure compatibility and optimal performance.
