This system provides 3.5 Inch of adjustable front lift with new forged torsion keys specialized for this 3.5 Inch front lift. Taller differential drop spacers and skid plate spacers are included, as well as new taller bump stops round out the front suspension. Our popular OE style cast iron 2 Inch tall rear lift blocks with new longer U-bolts provide the right rear lift for a strong stance. And to make it all ride and handle to match the truck's lifted look, we include new front/rear Bilstein 5100 series shocks.
