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.
