I lower my 2006 Silverado 1500 Rusty Duck Garage Shop Truck. Installing 2 inch drop spindles and a rear flip kit. I also install a rear flip kit and C Notch. Very similar to the drop in an OBS truck or a Square Body. I remove the body side mouldings and buff out the paint on the truck. I also installed 20 inch Tahoe wheels and tires. Then we took the truck out to Woodburn Drag strip for a little testing and tuning at the drag strip. OBS Cat Eyer Short Bed
