DmaxStore Note:

  • Access to grease fittings on your upper control arms can often be a pain. Kryptonite has eliminated this problem by changing the locations on our newest version of the upper control arms. The hardware kit with your arms include multiple grease fittings as well as grease port plugs. This allows you to have great service ability no matter how your upper control arms sit.


  • (Kryptonite No Fine Print Lifetime warranty)-Kryptonite steering and suspension components are warrantied for life to their original purchaser. This warranty is against any manufacturer defects, premature wear or breakage. Race it, jump it, off road it, sled pull it, wreck it, lift it, level it, lower it, I think you get it? We don’t care. If you can break it we will replace it. Kryptonite products must be purchased from an authorized dealer.
