Built for Dodge Ramcharger and Plymouth Trailduster owners who want aggressive ground clearance without sacrificing ride quality, this 4-inch lift kit raises the front of your vehicle to match rear height for a leveled, flush look. You'll gain up to 35" of tire clearance while maintaining factory-like ride geometry through a raised steering arm that keeps suspension angles optimal.
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
- Front and rear lifted leaf springs — engineered to raise ride height while maintaining suspension compliance and off-road articulation.
- N3 shock pair (front and rear) — 10-stage variable high-pressure nitrogen-charged shocks with 18mm spring-loaded piston rod and 54mm cooling body for smooth highway and off-road performance.
- Dana 44 steering block — repositions the front steering arm to maintain factory caster angles after lifting.
- Spring bushing and sleeve kit — isolates the leaf spring assembly for reduced noise and improved durability.
- U-bolt kit — fastens springs to axle with hardware.
- Installation hardware — all fasteners and brackets needed for assembly.
Important notes
- Does NOT fit models equipped with Cummins diesel engine.
- ONLY fits models with Dana 44 front axle.
- New rear leaf springs replace factory-equipped block — removal of OE rear block required.
- Recommended tire size is 33"–35" with proper wheel backspacing to avoid clearance issues.
