Rancho Suspension RS66507R9-3 Suspension Lift Kit Box 3 of 3

The Rancho RS66507R9-3 is Box 3 of 3 for the complete RS66507R9 suspension system, designed to provide a 3-inch front lift and level your Ford F-150. This box contains essential components of the complete lift kit system that must be ordered together with RS66507R9-1 and RS66507R9-2 for a fully functional installation.

Complete System Overview:

The RS66507R9 system is engineered to lift the front by 3 inches while rear blocks raise the back an additional 1.5 inches to level the truck. The complete kit accommodates up to 35-inch tires and maintains OE alignment specifications without affecting the electronic stability system.

System Features:

• Rancho RS9000XL struts and rear shocks with nine-position adjustable damping control
• Tubular upper control arms with pre-installed ball joints for superior strength
• 1.5-inch polyurethane rear lift blocks with u-bolts
• Sway bar spacers to correct end link angles for improved roll and sway control
• Complete mounting hardware included
• Greaseable zerk fittings for easy maintenance

Performance Benefits:

The RS9000XL shocks and struts feature nine levels of adjustment, allowing you to customize damping firmness for on-road comfort and off-road capability. Settings 1-3 provide on/off-road flexibility, 4-6 deliver performance similar to RS5000 shocks, and 7-9 offer enhanced performance for towing applications. The control arms maintain ball joints in their normal operating range while providing additional caster for improved alignment and increased wheel travel.

Important Installation Notes:

All three boxes (RS66507R9-1, RS66507R9-2, and RS66507R9-3) must be ordered for a complete kit. The system allows reuse of OE wheels and tires, though trimming may be required for 35-inch tires. Professional installation and post-installation alignment are recommended. Backed by Rancho's limited lifetime warranty.
