on my 85 stepside and the 88 d100 440 truck I used a front rear leaf spring hanger to replace the rear shackle hanger. then flip the shackle over.

on a 4x4 with axle under spring it lifts truck 4-5 inches

on a 2x chassis it moves spring down away from frame rail to make room for a axle on top of spring and a set of car shock plates with 3 inch u-bolts

called a flip flop. I have done about 6 trucks already. I run a stock front end set up with the rear flip flop. gives a nice stance, ride and handling.

FYI. on the 440 truck I used an A-body 8 3/4 to tuck 12 wide rims with a set of 29x15x15 M/Ts in the fenders.

on my stepside I have a 67 polara C-body 8 3/4 tucking a set of 10 inch rims and 29x9.50x15 tire.

it will drop the rear bumper level with the front bumper, still haul a 440/727 in the bed with out hitting frame rail, no wheel ho off the line,stock front end with a sway bar clears a parking stop

this is why I don't lower the front and ajust with tire size. whacked my swaybar end links on the parking stop and broke them.

make the truck ride and handle like a car on the street.
