UN93 & UN173 Suspension Conversion Kit with Heavy Duty Coil Springs and Shock Absorbers
ONLY FITS 4 WHEEL DRIVE (4WD) MODELS
Order Includes: (2) Rear Coil Springs, (2) Rear Shocks, (2) Insulators
Suncore’s Coil Spring Conversion Kit is designed to eliminate your rear air springs on your first generation 4 Wheel Drive Lincoln Navigator or Ford Expedition.
Two rust resistant, powder coated coil springs fit directly in place where your air springs rested, and top and bottom insulators are included to keep the metal springs from rubbing against the metal mounting locations. Two 4 Wheel Drive rear gas shock absorbers are also included with these coil springs, giving your vehicle better handling and dampening even when towing and hauling. The conversion process is a quick job even for the DIY mechanic, and detailed instructions are included with every purchase. This kit will not work on 2 Wheel Drive Models.
