Tire & Wheel Info

35×12.50 tires on a 17″ or larger wheel with 3.25″ to 4.75″ backspacing.

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

Exhaust spacer for front drive shaft clearance is included – used on 2012-2015 models only.

Product Overview

The 4″ lift for the Jeep Wrangler JK sets the standard for performance both on road and off. Pre-set replacement coil springs minimize settling, provide exceptional ride quality and the rear coils are rate specific for 2 or 4 door models. Track bar angle increases as the vehicle is raised, and bar length becomes a real issue when lift height exceeds 2.5″. The resulting track bar bind causes the chassis and axle to continuously “tug” against one another, resulting in uneven ride height (side-to-side), chassis / frame misalignment and unwanted “roll and yaw”. Front track bar correction is accomplished via a new REFLEX adjustable track bar. This route is preferred over using a relocation bracket because the bar’s arc of travel must remain in sync with the drag link’s arc of travel; if they get out of sync, steering wheel “kick” will result. A track bar relocation bracket is used at the rear axle since there are no steering geometry issues to contend with. Compression travel is controlled via unique machined aluminum receiver cups in the front and replacement closed-cell foam dampeners in the rear. Extended length sway bar links with factory style, tie-rod type upper ends, front / rear brake hose relocation brackets and emergency brake cable brackets are also included. Nothing is left unattended with this kit and it is packaged complete with Superide, Superide SS Series by Bilstein or FOX Shocks.

Superlift’s new High-Articulation Reflex Control Arms for the Jeep JK are the only arms on the market feature dual offset forged ends. The offset forged ends are equipped with the patent pending Reflex bushings to create the most advanced combination of off-road performance and on-road handling characteristics ever offered. Superlift flexologist have taken the next step in the evolution of flex by combining the patent pending Reflex bushings with the best designed Jeep JK control arms and track bars on the market.
