92159400A *1594BAG3* 1594BAG3 08-10 F250 4.5 OR 6” SUSPENSION KIT Thank you for choosing Rough Country for your suspension needs. Rough Country recommends a certified technician installs this system. In addition to these instructions, professional knowledge of disassemble/reassembly procedures as well as post installation checks must be known. Attempts to install this system without this knowledge and expertise may jeopardize the integrity and/or operating safety of the vehicle. Please read all the instructions before beginning the installation. Check the kit hardware against the parts list. Be sure you have all the needed parts and understand where they go. Also please review the tools needed list and make sure you have needed tools. PRODUCT USE INFORMATION As a general rule, the taller a vehicle is the easier it will roll. We strongly recommend seat belts and shoulder harnesses should be worn at all times. Avoid situations where a side rollover may occur. Braking performance and capabilities are decreased when significantly larger/heaver tires and wheels are used. Take this into consideration while driving. Also, speedometer recalibration is necessary when larger tires are installed. Do no add, alter, or fabricate any factory or after-market parts which 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. This kit is packaged as a leveling kit—raising the front 6” and the back 5”. If you desire a different look or if the vehicle has a tool box or added weight in the rear, please consult with your sales representative about block / u-bolt options. This 6” suspension system was developed for 37x12.50x17 tire on an after market wheel w/ 4.5” back spacing. If equipped with factory rear contact overload springs, please note that they will need to be removed with the addition of the block /add-a-leaf combination on this kit. NOTICE TO DEALER AND VECHICLE OWNER Any vehicle equipped with any Rough country product must have the “Warning to Driver” decal installed on the sun visor or dash. The decal is to act as a constant reminder for whoever is operating the vehicle of its unique handling characteristics. INSTALLING DEALER—It is your responsibility to install the warning decal and to forward these installation instructions on too the vehicle owner for review and to be kept in the vehicle for its service life.

Chock front wheels and jack up the rear of the vehicle. Secure with jack stands on the frame rail. 2. Place a floor jack under the rear differential on the rear axle. Using a 18mm wrench for the upper, and 19mm and 15mm wrench for the lower, remove the stock shock absorbers, retain the stock hardware for reuse. 3. Using a 24mm socket, remove the stock u-bolts. Use the floor jack to lower the axle assembly to allow for lifted block installation. Retain the factory axle block if equipped. 4. 6” Kit—Remove the spring eye bolts and nuts and remove the spring. If equipped with factory overloads, the top mounted spacer block and top mounted overload spring must be removed. The top spring plate may need to be drilled out to accept the nut for the new spring center pin. Make sure before starting that you have access to a drill and a 13/16” to 7/8” drill bit. Have c-clamps in place on either side of each strap before center bolt is removed. 5. Unbolt center pin and remove. Un-clamp leaf spring. CAUTION -Take care when releasing the c-clamps since the springs are under load and will “spring” apart when released. 6. Position add-a-leaf under the next longest leaf of the spring pack.
