Built for Ford F-150 Tremor owners who want aggressive ground clearance and a balanced stance without compromising reliability. This 4-inch lift kit levels the front of your truck with the rear while opening up tire clearance up to 35 inches — all with the same track width as factory for predictable handling both on and off the road.
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
- N3 Shock Pair — Premium dampers engineered to handle the added height while maintaining ride quality and control on rough terrain.
- Aluminum Knuckles — Forged aluminum construction delivers OE-level quality at 50% lighter weight than traditional steel, reducing unsprung mass for quicker steering response and improved handling.
- Strut Spacers — Provide the lift geometry necessary to maintain proper suspension angles and component clearance.
- Front & Rear Crossmembers — 1/4-inch thick plate steel members deliver uncompromised strength and a finished look; fabricated design is stronger and longer-lasting than cast alternatives.
