4.5 Inch Lift Kit | N3 | Diesel | Ford F-250/f-350 Super Duty 4wd (2023-2026)

Built for diesel Super Duty owners who want to eliminate factory rake and run 33–35-inch tires with a commanding stance — this Rough Country 4.5" lift kit delivers front-to-rear leveling, boosted ground clearance, and a clean, aggressive profile without compromising ride quality or handling geometry. Radius arm drop brackets correct caster alignment to preserve factory drivability, while heavy-duty fabricated rear blocks and anti-axle wrap technology outlast standard cast options.

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

Important notes

• This kit is engineered for diesel-powered F-250 and F-350 models only. Due to variances in motor weight, it does NOT fit gas-engine models.
• Does NOT fit models equipped with the Tremor Off-Road Package, which includes a factory 1.5-inch lift that creates incompatibility.
• Does NOT fit dually configurations.
• Designed to clear up to a 35" tire with proper wheel backspacing and offset — confirm your wheel fitment before installation.
