Get your GMC Sierra 2500HD in the air with this affordable 3.5 inch suspension lift kit from Tuff Country EZ-Ride Suspension. Once installed this kit will allow you to fit up to 33" tall tires (35 inch with minor trimming). Included in this suspension lift are upper control arms with poly bushings, re-indexed torsion bar keys, front shock extension kit, front differential drop kit along with cast iron blocks and extended u-bolts for the rear. New shock absorbers are not required.

IMPROVED !!! This lift kit has been redesigned with these upgrades:
1. Re-enforced control arm eyelets.
2. Includes suspension limiting straps.
3. Includes control arm bump stops.

Made in the USA for a Reason - Since 1988 Tuff Country EZ-Ride Suspension has been and still remains one of the very few suspension lift kit brands that manufactures, designs and packages its products in the USA. Why does this matter? Buy a lift kit from nearly any other brand that imports their products from overseas and you will get inferior steel, components and hardware. Many brands will also leave out important components that are crucial to proper suspension geometry. All can lead to fitment, alignment and sagging issues down the road. While Tuff Country may not be the cheapest lift kit on the market, quality components and happy customers are a higher priority.

Note: To purchase Tuff Country 13085KN (w/SX8000 Shocks) please select in options above. Extended shocks are not required to install this kit.

Tuff Country has been producing quality suspension products for over 25 years and backs all lift kits with a limited lifetime warranty. image

Easy and affordable with good results
This kit is easy to install and exactly what I expected. I had cranked my torsion bars up but the ride was really rough. With the kit installed, the ride is really nice...unbelievable actually. and I installed 35 inch tires. I would go with 33's next time as the 35's are a little too big and rub some.
