PRODUCT USE INFORMATION

WARNING

• 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. Generally, braking performance and capability are decreased when larger/heavier tires and wheels are used. Take this into consideration while driving. 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 is not recommended.
• 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. If questions exist we will be happy to answer any questions concerning the design, func-tion, and correct use of our products.

NOTICE

• The electric power steering must be unplugged before any of the steering components are removed. Failure to do so may cause damage to the electric power steering.
• Trucks equipped with a mass damper on the front diff, the damper will have to be removed.

This suspension system was developed using a 305/55R20 tire on a 20 x 9 wheel with +1mm offset. Minimal trimming is required. If wider tires are used trimming may be required. Due to manufacturing, dimension variances, and inflation, all tire and wheel combinations should be tested prior to installation on all oversized / wider then stock tires and wheels.

DEALER AND VEHICLE OWNER

POST INSTALLATION INSTRUCTIONS

1. Check all fasteners for proper torque. Check to ensure for adequate clearance between all rotating, mobile, fixed, and heated members. Verify clearance between exhaust and brake lines, fuel lines, fuel tank, floor boards and wiring har-ness. Check the steering gear for clearance. Test and inspect the brake system.
2. Perform a steering sweep to ensure front brake hoses have adequate slack and do not contact any rotating, mobile or heated members. Inspect rear brake hoses at full extension for adequate slack. Failure to perform hose check/ replace-ment may result in component failure.
3. On some vehicles, the front lower skirting will need to be trimmed if using certain wheel /tire combinations and with heavy offset wheels. Trim only as needed.
4. Activate the four-wheel drive system and check the front hubs for engagement.
5. Have a qualified alignment center align the vehicle immediately. Realign to factory specifications. The following are the recommended specifications:
   • Caster in degrees 4.0 +-1.0
   • Camber in degrees -.4 +-.8
   • Toe In in degrees 0.1 +-.2
6. Perform headlight check and adjustment to proper settings.
7.  Check and retighten the wheels at 50 miles and again at 500 miles.
8. All kit components must be retightened at 500 miles and then every three thousand miles after installation. Periodically check all hardware for tightness.
9. Install “Warning to Driver” decal on the sun visor
   Note : Installation of larger tires will require speedometer recalibration.
