4" Short Arm Lift System

Our 4" lift system raises the performance standards for both on and offroad. New pre-set coil springs (fully compressed and stressed in the manufacturing process) provide lift while maintaining factory ride characteristics. Drop brackets relocate both the factory upper axle-to-frame links and the new Rock Runner lower links. These components help restore proper suspension geometry, steering alignment, and driveline angles. New front / rear adjustable track bars center the axles side-to-side, improve on road handling characteristics, and increase offroad suspension travel. A dropped pitman arm reduces steering linkage angles. Front and rear replacement anti sway bar links prevent bar preload. Superlift's Slip-Yoke Eliminator Kit, offered separately, is required to relieve rear driveline angle. The 6" system is capable of clearing most 33" diameter tires on standard offset wheels, providing the jeep is not excessively heavy.

Base kits offered with your choice of 3 different performance shock options; Superide, Superide Select Series (SS) by Bilstein or Superide Select Series with a remote reservior (SSR).

4" Short Arm Rock Runner™ Lift System

In addition to the standard Superlift 4 Inch Short Arm Suspension Lift Kit above these Rock Runner™ Lift Kits include the additional Rock Runner Kit. The Rockrunner design has many advantages over other types of replacement links. The most common competitors’ links are one-piece units with some type of pivoting eye bushing (like a Heim joint). Superlift’s primary advantages are: a longer service life, quiet operation, less vibration and shock-load transmitted from axle-to-chassis, and link length is adjustable so driveline and steering alignment can be dialed-in.

Links feature factory type, steel encased rubber bushings at the frame ends, for durability, flexibility and quiet operation, and high-density, greasable Urethane bushings at the axle ends for improved control. Lower links constructed of 2" OD x .188" wall thickness DOM tubing. Uppers are 1.5" OD x x.188" wall.

Base kits offered with your choice of 3 different performance shock options; Superide, Superide Select Series (SS) by Bilstein or Superide Select Series with a remote reservior (SSR).

Steering Stabilizer

A steering stabilizer is basically a shock absorber for your steering system. It allows unrestricted gradual movement, but resists sudden shock. Stabilizers also combat other forces that induce tire shimmy, such as larger / heavier tires and wheels, and slack in your suspension and steering systems that occurs from normal wear. Some vehicles are factory equipped with a stabilizer, but like most stock shocks, they are barely adequate. Look for leakage where the shaft meets the cylinder body. Factory replacement cylinders, single kits and dual kits are offered. Boots for Superide stabilizers are sold separately; refer to the website's Urethane Shock Boot section.

Superlift Adjustable Track Bars

The track bar acts as a locating and stabilizing link between the axle housing (front or rear) and frame. When a vehicle is lifted the track bar needs to be lengthened and / or relocated or binding occurs. If unaddressed, the frame and axle housing will continuously "tug" against each other resulting in "roll and yaw" and "steering wheel kick" (see Glossary). Additional symptoms are tires being un-centered in relation to the fender wells, and the vehicle sitting low on one side (the track bar's upper end side).

Speed Sensor Calibrator by Superlift

Our TruSpeed calibrator addresses all speed signal-related problems; it doesn't just correct the speedometer. How? The TruSpeed module installs in-line with the factory electronic speed sensor and converts the wrong speed signal into the correct one for your vehicle's new tire and/or gear ratio combination.

Superlift Sway Bar Quick Disconnects

The factory anti-sway bars are great on-road, but they really limit the suspension's ability to twistup and articulate in low speed off-road situations. Superlift's Quick Disconnects give you the best performance traits of both worlds, and are a breeze to use. On each side simply pull the pin, unscrew it, pivot it upward, strap it up and go! Reconnecting the bar is just as easy... no tools, no rattles, no alignment problems, and no hassles.

Slip Yoke Eliminator Kit

Slip Yoke Eliminator Kit for use on NP-231 transfer case Part No. 5080 for Jeep TJ, YJ, XJ This heavy-duty transfer case tail-housing conversion allows the use of a bolt-on rear driveshaft yoke in place of the weaker slip yoke design found on most Wranglers (YJ and TJ) and Cherokees. The kit does not fit NP-247 or NP-207 transfer cases. Our new, shorter transfer case tail housing assembly permits the use of a longer rear driveshaft to decrease driveline angle and the associated vibration.

A larger diameter 32-spline output shaft, the use of needle bearings instead of journal bushings, and a pressure-sealed bearing housing make this kit a no-brainer for the serious off-roader. When used with a 3" to 4" suspension lift, the lift's transfer case lowering hardware can be removed resulting in increased ground clearance. Kit includes an output yoke for a 1310 series U-joint. Driveline combinations vary, requiring different shaft lengths and pinion U-joint sizes. With this in mind, we recommend that you purchase the required new rear driveshaft locally, or contact one of the nationally known Jeep driveline specialists.

Bullet Proof Brake Hoses

Bulletproof Series Kevlar reinforced braided stainless steel brake hoses... Superlift's Bulletproof hoses are simply the best brake hoses you can buy. We start with a °Teflon inner bladder that is surrounded with a °Kevlar inner braid (the same stuff used in bulletproof vests). The Kevlar layer is then wrapped in a rubber sheathing followed by stainless steel braid. Finally, the whole thing is wrapped in a plastic sheathing. This combination virtually eliminates hose expansion for better pedal "feel," improved braking performance and superior resistance to chafing. Additionally, Bulletproof hoses feature crimped ends and a factory-style steel leader-tube at the disc brake caliper to ensure the hose stays routed away from potential hazards, such as tires and wheels, suspension and drivetrain components. This leader-tube, a critically important routing feature, is normally not found in other braided hoses.

Bulletproofs™ are not just cool-looking, proper length hoses; they noticeably improve brake system performance which is definitely welcomed with larger / heavier tires.

eXtreme Ring - Differential Protector

As all off-roaders know, a 4x4's differentials are its lowest-hanging components. Diff covers are easily damaged by off-road obstacles and even urban debris -- their thin sheetmetal-like material can be deformed or peeled away from the differential housing upon impact, resulting in oil leaks and even internal damage. Superlift designed the eXtreme Ring™ for both hardcore 4x4 enthusiasts and those looking for a functional yet fashionable way to enhance their vehicles' undercarriages. The eXtreme Ring™ differential protector is constructed entirely of laser-cut 1/4" steel plate for superior strength and an exact fit as well as to give the "S" logo a 3-D effect. The ring reinforces the seal area while providing valuable frontal protection. For durability, eXtreme Ring™s are finished in yellow/gold zinc chromate. Over time, this finish develops a ruggedly elegant patina while continuing to deter rust. Applications are available to fit most popular American trucks: Chevy, Ford, Dodge, and Jeep - including the complete Dana axle line.
