Notes:

  • 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.
  • Cam Bolt Kit will Not Work with an Upper Control arm drop lift kit. They will only fit if your Upper Control arms remain in the stock location. Contact us with any questions regarding this

Kryptonite on 2013 2500 HD Duramax

Install was an easy non issue install. Happy to have every moving part greasable. Ride is definitely better. Crisp control. Gained more caster angle that really helped since my lift kit has 6" taller knuckles.

Looks like great quality

It took me a while to find time to install these UCA's along with the center link, tie rods, idler arm with support and bracket, and the pitman arm. I had heard it was difficult to replace the pitman arm but it was pretty easy and everything went very well. I haven't yet welded in the support bracket for the idler support or had the truck realigned, but I am expected to be very happy. The parts all incredibly strong and a great improvement over stock. Stay tuned for future reports.
