Quick Overview

For optimal performance, upgrade to Skyjacker's 8.5" Class II 4-Link lift kit for your Ford F250 or F350. All necessary components are included to let you install those 38" tires for a level and aggressive stance. The variable rate coil springs were designed so the rate is softer on the highway using the first 3.5" of travel. The spring rate will then increase as the coils compress past the first 3.5" of travel for enhanced offroad performance.
