The front differential assembly is also lowered to keep CV axle angles in check. This is accomplished by using two, one-piece tubular crossmembers that span from frame rail-to-frame rail. Superlift's new control arm brackets tie into these crossmembers along with "kicker" braces to form an exceptionally strong assembly.

The truck steers through a centerlink. Bracketry lowers the factory centerlink to keep the tie rods in phase with the lower control arms. A greaseable stabilizing link regulates centerliink movement and reduces the load and stress transmitted to the pitman and idler arms.

Superlift recommends nothing larger than a 12" (actual) wide, 36" tall tire mounted on a 10" wide wheel be used for anything other than exhibition or show.

Front track is NOT increased; CV axle angles remain within stock spec's; allows the use of most 16" 6-lug wheels w/standard offset; special wheels are not required & vehicle can be run with stock tire & wheel combo; dual front shocks and hoops are included.

• Retains factory ride quality, steering geometry and CV axle angles

• Load bearing bracketry made of .01875" thick plate steel or DOM tubing

• Centerlink stabilizing link makes steering more responsive & extends pitman/idler arm life

• Full-width differential/control arm crossmembers provide lateral rigidity

• Crossmember kicker braces add strength front-to-rear

• Skid plate protects front differential

• Front/rear Superide, Bilstein or SSR Remote shocks with yellow boots

• 99 & later models with Autotrac require a Dual Cardan driveshaft.

Tuff Country EZ-Ride Suspension's Chevy / GMC "Spindle/Sub-Frame" suspension lift kits make installation easier than ever. By using the combination new extended spindles and a one-piece sub-frame the amount of brackets and pieces required has been more than cut in half. A one-piece sub-frame will also help to eliminate annoying squeaks and rattles.

• Simple bolt-on installation

• New spindles eliminate need to drop upper control arms

• One piece sub-frame gives increased strength and helps to eliminate squeaks and rattles

• Includes lateral compression arms

• 6" lift allows use of 35x12.50 tires

Tuff Country EZ-Ride Suspension's new "Strong" Chevy  lift kits use new extended steering knuckles and a three-piece sub frame that includes two cross members that are connected by a heavy duty skid plate. This skid plate is designed to protect the front differential and stabilize the cross members for unmatched strength and durability. This design also allows for an easier and quicker installation. Differential drop brackets and torsion bar drop brackets keep everything in alignment. Also included are lateral compression arms which along with the 3-piece sub frame strengthen and stabilize the front end.
