5.5 Inch Lift Kit w/ Radius Arm | Ram 2500 (19-26) 4WD | Gas

Built for Ram 2500 owners who want 5.5 inches of commanding height without compromising truck geometry — this BDS radius arm lift kit preserves caster and steering feel while clearing substantially larger tires. You get front and rear coil springs engineered for the weight of a heavy-duty diesel-alternative platform, plus all the brackets and hardware to bolt straight to your frame.

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

• Radius arm upper and lower — engineered geometry that corrects caster for the 5.5-inch lift and keeps your steering responsive and safe over the long haul.
• Front coil springs — tuned for gas engine weight and maximum tire load while maintaining ride quality on road and trail.
• Steering stabilizer bracket — keeps vibration and feedback controlled as you run bigger rubber.
• Complete hardware kit — every bolt, bushing, and bracket to finish the job right.

Out back

Rear coil springs matched to the front for level ride height and balanced articulation, paired with mounting hardware that secures to your existing rear axle perches.

Pick your shocks

• NX2 Nitro Series — comfortable daily driver feel with solid off-road control; the best value for weekend warriors and truck enthusiasts.
• FOX 2.0 Performance Series — tuned damping for responsive steering feedback and improved body control on and off pavement.
• FOX 2.5 Performance Elite — premium damper technology with external reservoirs and adjustable compression; built for serious terrain and trophy trucks.

Important notes

• This kit is engineered for 2019–2026 Ram 2500 4WD models with gas engines only. Diesel variants require a different architecture.
• Confirm your tire size and wheel offset with Road Runner before ordering; larger tires and aggressive backspacing can interfere with suspension travel.
• If your truck is equipped with factory air suspension (rare on this model), you will need to convert to coil springs before installation.
