      • RBP Lift Kits are the ultimate in off road suspension lift kits.  In true RBP fashion, our lift kits will let you pull double duty and have your daily driver handle better than it did stock, and still tackle the off road terrain like a pro.  This 4" lift kit for your 2017 Ford F250/F350 SuperDuty 4WD is Made in the USA and will allow you to clear up to a 37x12.50" tire. The RBP 4" suspension lift kit system comes complete with everything needed to complete the install allowing for improved ride quality and performance.  Up front the truck will receive a set of full length replacement coil springs designed specifically to offer improved on-road/off-road performance with the weight of the diesel Super Duty. To reposition the front end and correct caster a pair of heavy duty replacement radius arms that bolt in place of the factory stamped steel arms. These arms are built from high strength 1/4" steel, boxed and fully welded with large 2.5" greaseable bushings to isolate road vibrations. Steering correction comes from a massive forged drop pitman arm to improve operating angle while a massive 1/4" steel fabricated track bar drop bracket is used to recenter the front end and keep the steering linkage angles in phase for predictable handling. Also included for the front of this 4" lift kit are sway bar relocation brackets to correct sway bar operating angle, brake line drop brackets to reposition the factory lines, bump stop extensions to control suspension compression and new steering stabilizer mounts to install the RBP nitro single stabilizer cylinder in place of the factory steering stabilizer.  For the rear of this 4" lift system, a replacement block is used to lift and level the stance, and eliminate the need to stack blocks. These kits maintain the factory leaf springs and overloads so your truck maintains its tow capability.  A 5" fabricated block has an integrated bump stop wing and bolts into place using a pair of extended black e-coated u-bolts. Due to the factory equipped 2-leaf main springs or a 3-leaf main springs w/ overload, RBP offers the right rear box kit with u-bolts to fit your particular setup.   This 4" RBP kit includes our premium nitro shocks for a great ride.  All RBP Lift Kits are backed by a Limited Lifetime Warranty - so you're covered, no matter what.  With this amazing RBP Lift Kit package, you can tackle the streets of the city, or the trails in comfort, style and performance.
