6 Inch Lift Kit | Diesel | No Ovld | V2 | Ford F-250 Super Duty 4wd (15-16)

Built for F-250 Super Duty diesel owners who want serious ground clearance without sacrificing drivability, this 6-inch lift kit transforms your truck for trail duty while maintaining factory handling geometry. The kit delivers up to 37-inch tire clearance and uses radius arm drop brackets to preserve proper caster angles — critical for keeping your steering feel and response predictable after the lift.

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

• 548 Kit Box — Houses all structural and attachment components engineered for F-250 Super Duty (15–16) fitment.
• 6-inch D-Coil springs — Lifted coil springs that provide the core lift height and support your truck's weight with tuning for both highway and off-road use.
• Radius arm drop brackets — Allow proper caster alignment to maintain factory handling characteristics and reduce bump steer after the lift.
• Fabricated anti-wrap rear blocks — Stronger, longer-lasting alternative to cast blocks; specially designed geometry prevents axle wrap and binding under load.
• V2 Monotube shock absorbers (2 pairs) — Dual-purpose shocks valved specifically for F-250 applications, balancing on-road comfort with trail-tuned damping.
• Stainless steel extended brake lines and brackets — Accommodate the lift geometry without crimping or stretching factory brake lines.

Important notes

• Does not fit F-350 models or dually configurations.
• Requires exhaust modification to clear the front driveshaft — this is a common fitment step on Super Duty lifts and performed as part of installation.
• If your truck is equipped with a factory contact overload spring on the rear leaf springs (non-OVLD), confirm your configuration before ordering. This kit is designed for non-overload spring setups.
• Gas-model F-250s may also require exhaust modification depending on engine bay geometry.
