The net amount of ride height increase depends upon the age and use of the vehicle, wheel offset, and numerous other factors. Stated torsion bar ride height in- creases are based upon factory specifications. If the torsion bars were “cranked up” at some point in the past, expect a corresponding reduction in overall height increase with the new torsion keys. Note that torsion bars, like any other spring, are subject to fatigue and sagging over time. Also, torsion bars have different ratings depending on how the vehicle was equipped from the factory. In some cases, installing heavier rated bars (which can be purchased from a dealer) may be the only solution to regaining ride height lost from adding heavy aftermarket accessories, such as a winch bumper or snow plow.

Adjusting Lift/Leveling kit after installation
(1) Always wear proper eye protection! Position vehicle on a stable,flat surface and suspend front wheels, lifting by the frame with a floor jack or lift jack. Secure frame with jack stands. Chock tires and turn engine off prior to adjustment!
(2) Locate the two Torsion Key Adjusting Bolts in the cross member of your vehicle chassis.
(3) Using a ratchet wrench and 22mm socket,engage the Adjusting Bolt and SLOWLY turn CLOCKWISE to INCREASE ride height,or COUNTER-CLOCKWISE to DECREASE ride height. Each full turn of the Adjusting Bolt will alter ride height approximately 1/8″. Each half turn will result in a ride height change of approximately 1/16″. (4) Be sure to always check that both sides of the vehicle have been adjusted to the same ride height. Under no circumstances should this product be altered to adjust ride height beyond its design limits.

As a general rule, the taller a vehicle is, the easier it will roll. Offset, as much as possible, what is lost in rollover resistance by increasing tire track width. In other words, go “wide” as you go “tall”. Do not add, alter, or fabricate any factory or after-market parts to increase vehicle height over the intended height of the Rough Country product purchased. Mixing component brands, lifts, and/or combining body lift with suspension lifts voids all warranties. Rough Country makes no claims regarding lifting devices and excludes any and all implied claims. We will not be responsible for any product that is altered. Braking performance and capability are decreased when significantly larger/heavier tires and wheels are used. Take this into consideration while driving.

Step 1: Measure current front ride height. Take a measurement from the bottom of the wheel/rim to the lip of the fender on each side of the vehicle. Write down measurements to help in determining ride height after new kit is installed.
Step 2: Position vehicle on a flat surface or automotive lift. Suspend front wheels, lifting by the frame with a floor jack or lift jack. Secure using jack stands and wheel chocks. Be sure engine is turned OFF and vehicle is in PARK. Remove tire/wheel assembly on ONE side of vehicle.

Due to the wide on-vehicle adjustment range of this product,a “floating” feature has been designed into the adjustment system. This feature allows the Forged Adjuster & Bolt assembly to reposition in the crossmember as ride height adjustments are made.

Important! Ford/Lincoln vehicles with factory Air Suspension systems require an alternate installation procedure. Only install this product and adjust ride height

This kit is packaged as a leveling kit—raising the front 4”and the back 2”or raising the front 6”and the back 4”. If you desire a different look or if your truck has a tool box or something else that is going to bring the rear end down, please consult with your sales repetitive about option higher block and u-bolt options or the use of an add-a-leaf.
The 4”suspension system was developed for 35×12.50×17 tire on an after market wheel with 4.5”of back spacing.
The 6”suspension system was developed for 37×13.50×17 tire on an after market wheel with 4.5”of back spacing.
