4 Inch Lift Kit | Rear Blocks | Ford F-100 4wd (1970-1976)

Built for Ford F-100 4WD owners who want a leveled stance and aggressive look without sacrificing ride quality, this 4-inch lift kit raises your truck's front end to eliminate factory rake and deliver a commanding, truck-show-ready profile. You'll gain up to 35-inch tire clearance while maintaining proper suspension geometry with caster-corrected C-bushings and a track bar bracket — so your steering and handling stay predictable whether you're cruising or crawling.

Installed and serviced at Road Runner Wheels & Tires. Most lift kits go in the same day. Call (678) 400-6467 to schedule.

What's included

• 4-Inch Front Coil Springs — heavy-duty coils engineered to increase ride height without compromising ride quality or handling characteristics.
• N3 Shock Pair (Front and Rear) — nitrogen-charged, 10-stage velocity-sensitive shocks with a 54mm body and 18mm piston rod for superior damping and durability on and off-road.
• 7-Degree C-Bushings — correct caster geometry after the lift to maintain proper steering feel and suspension alignment.
• Track Bar Bracket — repositions the track bar for correct front-end geometry and safe handling at ride height.
• 2-Inch Rear Lift Blocks — raise the rear to level the truck's front-to-back stance.
• U-Bolts and Hardware — all fasteners and brackets needed for a complete, factory-quality installation.

Important notes

• This kit fits only F-100 4WD models with 3-inch wide rear leaf springs. Confirm your truck's rear spring width before purchase.
• The 35-inch tire clearance assumes proper wheel backspacing; verify offset and backspacing with our sales team to avoid rubbing.
