For 1965 to 1979 F250 medium-duty Ford 2 wheel drive trucks with twin I beam front suspension. Basic 3 inch front suspension lift includes coil springs, Autofab adjustable drag link for right wheel, 1 set of medium-duty small kingpin Ford I Beams aligned for 3-inch lift. Ford beams are inspected for kingpin fit, Straightened to factory specifications, have new pivot bushings installed, and are adjusted for both camber and caster alignment. Small kingpins measure 7/8 inch in diameter. Please keep in mind this pricing is for small kingpin F250 trucks only that come with the standard flat top coil bucket. We also do large kingpin, camper special trucks, etc but pricing will change depending on your particular front end. Note: if you have the tall coil buckets where the top of the coil spring is 2 inches above the shock mounting hole then select that option as the coils are more expensive and processing large king pin beams and steering adds to labor. Beams are subject to a refundable core charge of $400, please select that option unless you plan on sending us your beams first.
