SUPER DUTY 2.5” LEVELING 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 on the
back page of these instructions. 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. 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, speed ometer 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 with its new heavy duty track bar only fits trucks produced after 03/01/99—2000 models forward. If you
have a truck produced prior to this date this kit will not fit the vehicle. A difference of bolt size on the stock track
bar bracket does not allow the installation of the new track rod.
If the vehicle has a tool box in the rear or any other reason that the rear may be lower then normal this lift may not result
in a level look most often desired. Rough Country offers block and u-bolt combinations and add-a-leafs to raise the rear
of this vehicle to a look that is more desirable —contact you local distributor for details.
This kit was designed for use with a 305/70R-16 tire on a factory wheel. Any other variation will need to be verified before use to prevent possible clearance issues.
If you have any questions about this installation or the product included please call our customer service department at
800-222-7023.

the rear bumper support bolts (1 each side) on the
frame bracket as shown in Figure 1 using a 15mm
socket.
Figure 1
6. Gently pull the bumper outward as shown in Figure 2. Carefully remove the lighting harness plugs, and any other
wiring attached to the bumper assembly to allow for removal noting the routing of the wiring. Place the bumper assembly out of harms way to ensure that no damage occurs to the bumper.
7. The radiator cooler lower mounts will have to be removed to allow the cooler to move outward to gain access to the
front spring bolts. Remove bolts on both sides of cooler as shown in Figure 3 (Passenger Side Shown). Retain the
factory hardware for reuse.
Figure 2 Figure 3
8. Remove the factory track rod from the axle and the frame using a 30mm socket / wrench. Remove the factory track
bar. See Figure 4 & 5.

POST INSTALLTION INSTRUCTIONS
1. Check all fasteners for proper torque. Check to ensure there is adequate clearance between all rotating, mobile,
fixed and heated members. Check steering gear for interference and proper working order. Test brake system

fixed members, adjust lines/brackets to eliminate interference and maintain proper working order. Failure to perform
inspections may result in component failure
3. Readjust headlights to factory settings
