The Kryptonite No Fine Print Lifetime Warranty specifically states "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, wreck it, lift it, lower it, sled pull it, I think you get it? We dont care. If you can break it we will replace it." That's a pretty bold statement and would require a company that builds a solid product to offer it and still be in business.

KRYPTONITE STEERINGMany would argue that Kryptonite got its foot in the door with their massive steering tie rods for Chevy 2500HD and 3500s, or maybe it was their upper control arms for this application.

From these initial proving grounds, Kryptonite has vastly expanded their portfolio in providing steering linkages for Ram and Fords, Lifetime Warranty Wheel Bearings, ball joints, centerlinks, pitman and idler arms, and even complete suspension systems!

Worth the wait
"Everyone goes on about the wait time, and there was some, but these are crazy. CRAZY."
Not worth the wait.
"Called kryptonite directly to check on my order after waiting over 5 months person I spoke with was rude and had no customer service manners speaking over me with a bad attitude. Parts showed up one built to spec the other measure 1/4 inch different. Lack of quality for sure. I feel generous giving 2 stars. But hey the box it came in was nice and foam cut out securing the parts was greatly thought out. Save your money go with a different company."
Artwork!
"These arms are stout compared to the oem stamped arms. Bolt in upper ball joints are a nice addition and poly bushings to boot! Cannot go wrong with kryptonite products on GM/Chevy trucks."
Control arm
"Super duty is what I prefer"
Q&A
- Will this work correctly for a 03 chevy silverado 2500 hd with a 6 in suspension lift
- Yes, as long as it is replacing a factory upper control arm in the factory location,.
- Are the ball joints/control arm pivots greaseable? I’ve owned Uniball type uppers before and they did not have serviceable ball joints, they would squeak and scream sitting at a stoplight simply by turning the steering wheel 5 degrees. Ditched them and went back to OEM style MOOG uppers, Zero problems out of them.
- Yes the ball joints and frame bushings are greasable.
