Product Overview

Thank you for choosing Rough Country for your suspension needs.

Rough Country recommends a certified technician install this system. Professional knowledge of disassembly/reassembly procedures and post-installation checks is required. Attempting installation without this knowledge may jeopardize vehicle integrity and safety.

Product Use Information

WARNING: As a general rule, taller vehicles are more prone to rolling. Seat belts and shoulder harnesses should be worn at all times. Avoid situations where a side rollover may occur. Braking performance and capability may decrease with larger/heavier tires and wheels. Consider this while driving. Do not add, alter, or fabricate any factory or aftermarket parts to increase vehicle height beyond the intended height of the Rough Country product. Mixing component brands is not recommended.

Rough Country makes no claims regarding lifting devices and excludes all implied claims. Rough Country is not responsible for any altered products. Contact Rough Country for questions regarding design, function, and correct use of products.

NOTICE: The electric power steering must be unplugged before removing any steering components to prevent damage.

NOTICE: Trucks equipped with a mass damper on the front differential will require its removal.

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

NOTICE: DEALER AND VEHICLE OWNER

Any vehicle equipped with a Rough Country product should have a "Warning to Driver" decal installed on the windshield or dash as a constant reminder for the operator.

Post Installation Instructions

1. Check all fasteners for proper torque. Ensure 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 harness. Check steering gear for clearance. Test and inspect brake system.
2. Perform 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/replacement may result in component failure.
3. On some vehicles, front lower skirting may need trimming if using certain wheel/tire combinations with heavy offset wheels. Trim only as needed.
4. Activate four-wheel drive system and check front hubs for engagement.
5. Have a qualified alignment center align the vehicle immediately. Realign to factory specifications. Recommended specifications:
   • Caster: 4.0 +-1.0 degrees
   • Camber: -.4 +-.8 degrees
   • Toe In: 0.1 +-.2 degrees
6. Perform headlight check and adjustment to proper settings.
7. Check and retighten 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 sun visor.

Note: Installation of larger tires may require speedometer recalibration.
