This is the SUPERLIFT 6.5 Inch suspension lift kit for the, 1978 -79 Bronco and 1977-79 Ford F-100 & the 1977-1979 Ford F-150. With a SUPERLIFT suspension and a little more tire, your classic Ford will have an awesome stance and better off-road ground clearance.
This SUPERLIFT system is designed for owners looking to gain more ground clearance, wheel travel flexibility, and front-to-rear level stance. Our K512 addresses all of your lift kit needs in terms of product quality, durability, craftsmanship, and price. It includes everything you need to lift your legendary Ford pickup. SUPERLIFT does have personalized options and upgrades to enhance your install plus steering & handling performance.
Ford used their tried-and-true solid axle coil spring suspension with radius arms and a front track bar. It consists of two radius arms that locate the axle front-to-rear. The track bar handles the side-to-side axle location. The track bar helps locate and stabilize the frame (& body) in relation to the axle housing. The rear suspension configuration is a solid axle with leaf springs.
These radius arms attach to the axle above and below the axle’s centerline. These arms also control the ‘roll’ of the axle known as caster. The radius arm sandwiches a roughly diamond-shaped pad that is cast or welded on the axle. In between the two front pieces of the radius arm is a two-piece C-shaped bushing to absorb road vibrations and give the suspension some movement.
In stock form, the radius arms are parallel with the frame. Once lifted, the radius arms become angled because the axle end moves downward and the frame end remains fixed in the factory mount. To restore the lost caster, SUPERLIFT includes BOTH four (4) durable polyurethane degreed C-bushings (to replace the factory bushings) AND new radius arm to frame relocation brackets.
These brackets lower the radius arm’s rear location. This makes the radius arm run parallel to the frame and to ‘roll’ the axle back to its proper caster location. SUPERLIFT includes a replacement Adjustable Track Bar for the front. This allows precise frame-to-axle alignment. It comes complete with polyurethane bushings, metal sleeves & mounting hardware.
SUPERLIFT engineers developed these 6.5 inch front lift coil springs to give you the best ride and handling characteristics available. They’re pre-set to reduce fatigue in the steel, minimize settling and guarantee a consistent ride height. Shot-peened to increase tensile strength and allow maximum wheel travel without sacrificing the life of the springs.
In the rear, SUPERLIFT provides a pair of 2-inch add-a-leafs and 3 inch rear block kit. These long add-a-leafs install directly beneath the main leaf: the longest leaf in the leaf spring pack with the mounting eyes at each end.
Since the strength is added along the spring’s full-length, this positioning is most beneficial for combating spring/axle wrap-up. This positioning also allows a relatively thin material so ride quality is not harsh: only slightly firmer overstock due to the arch /lift height of the add-a-leaf.
The 3 inch rear block kit comes complete with proven cast steel blocks, U-bolts, nuts and washers. Included in this system is a set of four (4) Superlift hydraulic shocks absorbers. Superlift shock absorbers are designed to provide excellent ride quality, durability and longevity.
They feature 10-stage, velocity-sensitive valving for maximum control on or off-road without sacrificing a comfortable ride. Shock resistance is continually adjusted, depending on the terrain and vehicle speed.
