5.5 Inch Lift Kit w/ Radius Arm | Ram 2500 (14-18) 4WD | Gas

Built for Ram 2500 owners who want serious towing and hauling power without sacrificing ride quality. This 5.5-inch lift kit from BDS raises your 2500 while preserving OE caster geometry through a radius arm design — meaning your truck handles like it should, not like it's been twisted. Gain up to 37 inches of tire clearance and maintain factory driveline angles for long-term reliability.

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

What you get up front

• Coil-over front suspension — adjustable ride height and independent damping control for towing loads and terrain changes.
• Radius arm — preserves OE caster angle so steering geometry stays true and wear patterns stay even.
• Bumpstops and hardware — engineered to handle the new ride height without bottoming during compression.

Out back

Rear leaf springs accommodate the 5.5-inch raise and keep your payload capacity intact for work or weekend.

Pick your shocks

• NX2 Nitro Series — comfort-tuned damping for daily driving and light towing. Daily-driver value at the best price point.
• FOX 2.0 Performance Series — responsive digressive shocks with tuned compression and rebound, built for mixed road and light off-road duty.
• FOX 2.5 Performance Elite — fully adjustable compression and rebound with DSC technology. Maximum capability for serious towing, hauling, and trail work.

Important notes

• Designed for 2014–2018 Ram 2500 4WD gasoline engines only. Not compatible with 6.7L diesel or 2019+ models.
• Maximum tire clearance is 37 inches with proper wheel offset and backspacing. Confirm offset with your wheel builder or tech.
• Transfer case re-indexing may be required during installation to maintain driveline angles.
• Vehicles equipped with factory electronic locking differentials or air suspension require additional configuration at install time.
