Using your Kryptonite upper control arms is easy. First, make sure your truck is in the right model and year range (2001 - 2010 Chevrolet/GMC 1500/2500HD/3500HD or 2002 - 2009 Hummer H2, 8 lug trucks). When installing, follow the installation guide by clicking the provided link. If you choose to use the optional Kryptonite Cam Bolt Kit, note that it only works when your upper control arms are in the stock location. For maintenance, all ball joints and rod ends come pre - greased. Every 7,000 to 10,000 miles, add a small amount of grease to each joint. Don't over - grease them. Remember, if you're in a harsh climate or your truck has high miles, it's a good idea to replace the cam bolt kit. And always buy your Kryptonite products from an authorized dealer and complete the warranty registration within 90 days of purchase to enjoy the lifetime warranty, which covers manufacturer defects, premature wear, or breakage (excluding Heim Joints).
