2008-10 Ford F250/F350 Super-Duty 4WD 8 inch Front / 7 inch Rear (V8 Gas Engine). 2008 2009 2010 Truck SuperLift 8 Inch Lift Kit K857 Ford
This Kit uses 5 inch BLOCKS and ADD-A-LEAFS to raise the rear.
Includes two front and two rear Superide shocks. Front lift is achieved via replacement coil springs. The new Ford SuperDuty is very sensitive to caster angle change. As the truck is lifted, the frame-mounted radius arms cause the front axle to rotate, resulting in less caster angle. Incorrect caster angle makes the truck more difficult to steer, since the truck's normal tendency to self-center is reduced. Incorrect caster can also induce steering shimmy. One more point that emphasizes the importance of correct caster angle and steering geometry in general. as a truck is loaded, by adding cargo or trailer tongue weight, caster is lost as the vehicle's rear ride height drops. When hauling or towing, driveability is even more important. The 8 inch Lift system utilizes two methods of caster correction: standard type radius arm drop brackets that lower the rear (frame mounted) ends of the radius arms and a bracket that bolts to the front of the radius arm. Using the standard type radius arm drop at the frame end alone would overly stress the frame rails in addition resulting in an unpleasant appearance.
Features Diesel / Gas Engine specific coil springs ensure proper lift height and factory ride quality. Front compression travel-stop relocation brackets prevent suspension over-compression Track bar relocation bracket prevents bind, body roll and steering wheel kick Dropped pitman arm for the 6" lift reduces drag link angle Threaded front anti-sway bar extensions do not require cutting or welding Proper factory steering stabilizer angle is restored for optimum operation Front/Rear Superide shocks included.
