3 Inch Lift Kit w/ Radius Arm | Ram 2500 (14-18) and (2025) 4WD | Diesel

Built for diesel Ram 2500 owners who want level stance, 35-inch tire clearance, and corrected geometry without sacrificing ride quality — this 3-inch radius arm lift kit from BDS Suspension raises your truck 3 inches up front and 1.25 inches out back while preserving driveline geometry. Pro-Ride coil springs engineered for diesel weight keep the ride smooth, and the adjustable track bar keeps your steering dialed in at any lift height.

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

• Pro-Ride Coil Springs — full-length, diesel-specific progressive-rate springs engineered with high tensile steel and properly sized wire for maximum reliability and correct lift height without premature bind.
• HD Tubular Radius Arms — heavy-duty replacements for factory stamped steel, offering caster adjustment across a range of lift heights and OE-style rubber bushings at the frame mount for smooth, service-free operation.
• HD Adjustable Track Bar — built from 1-3/8" solid steel stock, pre-assembled with bushings and ready to bolt in factory mounting points, recenter your front axle and maintain proper handling geometry.
• Sway Bar Links & Brake Line Brackets — complete hardware to integrate the lift safely with your truck's steering and braking systems.

Out back

High-strength fabricated coil spacer, track bar relocation bracket, and bump stops round out the rear setup — paired with your choice of shocks below.
