aFe CONTROL Leveling Kits are made of billet aluminum and provide an adequate lift to the front of your vehicle to improve off-road performance while also eliminating the “nose-down rake” from the factory stance.High quality hardware is used for strength and durability. New connecting rods are included to reposition the front ride height sensors so all driving modes remain available. Polyurethane spring isolators allow the top plates of the OE shocks to be switched in order to prevent the springs from bowing. Installation of these leveling spacers can be done at home with the proper tools and safety precautions. Installing these spacers does require disassembly of the strut/spring. A spring compressor is not required due to the light amount of preload on the stock coil springs and extended shaft studs.
