Rocky Mountain Suspension Products, Ford F250, F350, Super Duty suspension lift kits

The 80-97 F250 and 80-85 F350 have a 2-piece Twin Traction Beam front axle with leaf springs. Heavier rated Superide springs are used for the Powerstroke diesel engines. The Superunner Steering System is included with the 6" lifts and offered separately for the 4" lifts.

The Superunner Steering System should be compatible with most other name brand 4" & 6" lift systems. It reduces linkage angle and keeps the tie-rods arc of travel in phase with the axle halves arc of travel. The result is a lifted truck that steers better than a stock one in most cases!

Kits use rear add-a-leafs or blocks. Systems use rear leaf springs. Shocks purchased separately.

The Softride springs manufactured by Skyjacker use tapered leaves to yield a lower spring rate and better travel, Teflon wear pads to help reduce interleaf friction, a "bolt" style clip to reduce leaf friction and shotpeening to compress the steel and increase its tensile strength.

Class I or standard lift kits feature two separate center hinge brackets and the Class II with a boxed and reinforced 1-piece center hinge bracket. The following shows Kits using a rear block and/or add-a-leaf to accomplish the rear lift and Systems using rear leaf springs.
