Prior to April 1, 2016, GM 1500 trucks had either cast steel or aluminum control arms. Trucks manufactured on or after April 1 feature stamped steel upper and lower control arms. Pro Comp�s new 4-inch (K1173B) and 6-inch (K1171B) kits will work on GM 1500s with aluminum or stamped steel control arms. If you have inventory of the previously-released Pro Comp OE aluminum application 6-inch (K1165B) or 4-inch (K1159B) kits, you can add the new Sway Bar bracket kit (90-60616B) that will allow you to use them on the new truck with the stamped steel control arms.
Pro Comp Suspension has spent the last two-and-a-half decades engineering, testing and manufacturing products that will give Jeep drivers the confidence to dominate whatever terrain is ahead. The Pro Comp Promise Life Time Warranty is forever. Pro Comp's warranty goes with the suspension products on Jeeps whether or not the Jeep owner is the person who originally purchased the product. Pro Comp Suspension can afford to give such a warranty because the products are produced at the Pro Comp facility in San Diego, California under exacting manufacturing standards. Pro Comp Suspension is the only suspension company with products that are tested under true driving conditions on outside roads, rather than simulated testing. Shop Pro Comp Suspension Now
