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

Built for Ram 2500 diesel owners who want 6 inches of lift without geometry compromise — this BDS radius arm kit preserves factory caster and driveline angles while opening up tire clearance. You get a complete front and rear solution, precision-engineered for the 2014–2018 4WD platform.

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

• BDS radius arm assembly — maintains proper caster geometry and prevents suspension bind at full articulation.
• Coil springs — matched for 6-inch lift height and load capacity on diesel trucks.
• Upper control arms — corrected angles to keep geometry square after the lift.

Out back

Rear leaf springs and shackles work together to deliver that full 6 inches, leveling the truck's stance and improving departure angles for trails and work sites.

Pick your shocks

• FOX 2.0 Performance Series — proven damping for daily driving and light off-road use on diesel loads.
• FOX 2.5 Performance Elite — premium compression and rebound tuning for aggressive trails and serious hauling.

Why customers pick this at Road Runner
