    Perfect Way to Lift Your Ride to Clear Larger Rear Tires

    Skyjacker utilizes blocks and U-bolts in its kits to provide rear lift. Available in 1.25", 2", 3.5", 4.5", and 5", Skyjacker ductile iron blocks with fixed center pins are tapered to correct pinion angle and prevent driveline vibrations. E-coated U-bolts are corrosion-resistant and offered in various shapes/sizes (e.g. square, round, semi-round) and lengths from 1.75" to 19".
