Product Description

Providing four inches (4″) of front lift and two and a half (2.5″) of rear lift, this Rancho F-150 suspension system easily lifts the front and rear while allowing for the use of a larger wheel and tire package. Stock 18- and 20-in. wheels can be re-used. System includes a heavy-duty, one-piece Rancho subframe made from high-strength low-alloy steel.
