2" Mild Lift — Leveling and Small Tire Clearance

Difficulty 2/54–8 hrs$250–6001966-1977

A 2" lift on an early Bronco is about tire clearance and recovering a sagged stance, not articulation. The early Bronco is leaf-sprung front and rear, so a "2-inch lift" means taller leaf packs (or an add-a-leaf), longer shocks, and an alignment to put caster back where it belongs. Done right it clears 33" tires and rides better than worn-out factory springs. It does not transform the truck off-road — for that, see the 4" lift.

A 2" lift gives enough room to clear 33" tires without rubbing, nudges the departure and approach angles, and levels a truck whose 50-year-old springs have settled. Because both ends of an early Bronco ride on leaf springs, the cleanest way to gain height and restore ride quality at the same time is new leaf packs rather than a spacer or a block.

Work one corner at a time so the axle never hangs unsupported. With the frame on jack stands and the axle supported on a floor jack:

  1. Remove the shock, then the U-bolts holding the axle to the spring. Loosen the spring eye bolt and the shackle bolt.
  2. Drop the old pack out. Fifty-year-old spring eye bolts and shackle bolts are frequently seized — soak them in penetrant ahead of time and have a torch and a spare hardware kit ready rather than fighting rounded heads on the trail of the job.
  3. Install the new pack, starting the fixed eye bolt first, then the shackle. Fit fresh greaseable shackles and bushings while it is apart — doing this later means tearing it down twice.
  4. Re-seat the axle on the spring center pin, torque the U-bolts in a cross pattern to roughly 70–90 ft-lb (verify against your kit's spec), and install the new shocks.
  5. Repeat per corner, then roll it off the stands and let the suspension settle before measuring ride height.

Any lift changes front-axle caster. Stock caster runs about 1–2° positive; a 2" lift rotates the axle and often drops caster below spec, which shows up as lazy steering return and wander. Caster shims between the spring and the axle perch (or a shop setting caster on the rack) restore it. If the truck already wanders before the lift, address the steering box and linkage first — the steering stabilizer and box brace guide covers what a stabilizer can and cannot fix. For shocks, the Rancho RS5000X or Bilstein 5100 in the correct extended length bolt to the stock mounts and handle trail chop well; shock selection is detailed in the shocks guide.

A 2" lift clears 33" tires in most applications, sometimes with light trimming of the inner front fender lip at full stuff. Confirm clearance on your own truck at full articulation before committing to a tire — backspacing matters as much as lift height, so cross-check the tire sizing and wheel backspacing guides. Going to 33s also pushes you toward regearing if you are running tall factory gears, since the taller tire drops your effective ratio.

A front and rear leaf upgrade with new shackles and bushings runs $400–$600 in parts; add $220 for a set of four shocks and roughly $40 for caster shims. An alignment at a shop that understands solid-axle Fords is $100–$150 and is not optional. Total out-the-door for a do-it-yourself 2" leaf lift lands around $450–$700 plus the alignment.
