4 Inch Lift Kit | Rear Springs | Ford Bronco 4wd (1978-1979)

Built for 1978–1979 Ford Bronco 4WD owners who want a leveled stance and aggressive look, this 4-inch lift kit raises the front to match the rear, delivering equal ride height from bumper to bumper. Rough Country's engineered springs and shocks work together to gain ground clearance and accommodate up to 35" tires while preserving that factory-like ride quality.

What's included

• 4-inch N3 Shock Kit — Premium 10-stage variable high-pressure nitrogen-charged shocks with 18mm spring-loaded piston rods and 54mm bodies for smooth highway and off-road performance.
• 4-inch Coil Springs (Front) — Lifted coil springs that raise the front and level the vehicle with a durable, consistent lift.
• 4-inch Rear Leaf Springs (qty 2) — Factory-strength leaf springs engineered to support the rear suspension at the new ride height.
• 7-Degree C-Bushings — Geometry correction brackets that maintain factory-like angles for steering and suspension geometry after lifting.

Important notes

• Vehicles with factory quad shocks (two front shocks per side) will use a single aftermarket shock in this kit.
• Proper wheel backspacing is required to safely fit up to 35" tires; confirm backspacing with our team when ordering.
