33 x 12.50 tire on a minimum of a 18" diameter wheel that is 8.5" wide with a 4.5 to 5.5" backspacing. - CAN NOT RUN STOCK 17-18" WHEEL

IMPORTANT DISCLAIMER: The provided tire/wheel fitments are approximate.

Actual dimensions of a given tire size can vary considerably from one brand to another.

Manufacturers’ wheel offset and backspacing measurement points are not always consistent.

Backspacing greatly impacts tire-to-fender clearance when turning.

Wheel width and backspacing influence whether the tires protrude past the fenders, and to what extent.

Considering these important factors, we recommend that you fit-check your tire/wheel selection prior to purchasing.

Minor cutting and / or welding required.

Can run 20" stock wheels with oversize tires. 18" or 20" aftermarket wheels require specific backspacing; min. 4.5"/ max 5.5".

Rear spring installation requires lowering / reinstallation of fuel tank.

Not compatible with Denali and Escalade.

Fits vehicles w/o Electronic Controlled Shocks

Front lift is achieved by installing spacers on top of the factory coil-over shock assembly. Pre-load rings, installed below the coil springs, slightly increase spring rate to help offset the additional loads created by running larger tires, and firms-up what would otherwise be a "spongy" ride. The factory upper control arms are retained and remain in their original location, while the factory lower control arms and axle housing are lowered, in relation to the frame. New Superlift replacement steering knuckles, made of cast ductile iron and machined in-house, span the increased distance between the control arms.

Superlift's geometry, from steering timing and linkage angles, to driveshaft and CV axle operating angles, yields optimal component service life and exceptional drivability.

Our lower control arm crossmembers are a one-piece, full-width, high-clearance design made of .25" steel plate, joined together by a skid plate that protects the differential and further reinforced by kicker braces.

Rear lift is via a 5" rear block and u-bolt kit.

The kit is packaged complete with rear Superlift Superide or Superide SS shocks by Bilstein.
