Tire and Wheel Info

33 x 12.50″ tire on standard offset 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.

Installation Notes

A small percentage of Jeeps with 4″ of lift (except Rubicon model) will require a Slip Yoke Eliminator (SLE) kit to reduce driveshaft angle / driveline vibration; this cannot be determined until the lift is installed, and the Jeep road tested. A SLE kit is required with lifts over 4″ (except Rubicon model).

Slip Yoke Eliminator (SLE) kit also requires a new, CV type rear driveshaft. Superlift does not offer these driveshafts due to the multitude of possible driveline configuration. Rubicon models do not require a SLE (they are factory equipped with a fixed-yoke), but Rubicon’s with 6″ of lift will require a CV type rear driveshaft. Contact your local driveshaft supplier or one of the national drivetrain specialists.

Installation Instructions

Product Overview

The Superlift 4″ lift for the Jeep Wrangler TJ platform covers all the bases. Lift is achieved via coil springs that are pre-set (fully compressed and stressed) during the manufacturing process to minimize settling.

The system also includes front and rear anti-sway bar links, a rear track bar extension bracket, longer bump stop extensions, front and rear lower control arms, a transfer case lowering kit and Superlift Superide or Superide SS shocks by Bilstien.

Options include front and rear adjustable track bars, Rockrunner swivel-link control arms and quick-disconnect sway bar links. A steering stabilizer and eXtreme Ring differential protectors are available as well.
