Cupping your lower control arms is a diy budget friendly way to get extra drop on your C10. By welding in a drop pocket, you gain about two inches more drop mounting the bag directly to the control arm. You pair this with 2.5 drop spindles and your crossmember is on the ground. I have the front diy slam kit and drop spindles on my website. www.simplec10.co Feel free to reach out if you need help bagging your c10 www.simplec10.co | SIMPLE.C10
