Kryptonite 2001-2010 Duramax, Stage 3 Leveling Kit w/ Bilstein Shocks – KR10STAGE3BIL


Product Highlights:

We have combined the highest quality components available at an unbeatable price. Look no further we have done it for you.

Kryptonite Upper Control arms are laser cut and welded into an extremely strong boxed design. Made with pride here in the small-town USA and backed with a lifetime warranty. Kryptonite UCA kits will improve the ride of any Stock, leveled, or lifted GM 2500-3500 HD truck but are also a great upgrade for your stock height truck. Kryptonite UCA’s are compatible with any stock or leveled 2500-3500 HD and most suspension lift kits.

Kryptonite upper control arms, correct the upper ball joint angle which is a problem with angles of the factory upper control arms after turning up the suspension. The alignment of the front end is also corrected so that it will fall into factory alignment specifications, something that is almost impossible on a truck leveled out with the factory upper control arms.

The adjustable torsion key provides up to 2” of lift and gives clearance to add up to 33″ wheels and tires. Our keys are guaranteed never to affect the OEM ride and will not add more pressure on the stock suspension components.
