3" Lift Kit with OK 2.5" Shocks by BDS Suspension
Take your 2003-2013 Dodge RAM 2500 and 2003-2012 RAM 3500 4WD diesel powered truck to the next level with this 3-inch lift kit from BDS Suspension. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 35" tires. The BDS 3-inch lift kit features fixed length, greaseable, heavy-duty round tubular construction upper and lower control arms that position the axle properly and adjust for proper caster and pinion angles.
Up front the lift kit includes diesel-specific Pro-Ride coil springs, heavy duty adjustable track bar, fixed length tubular upper and lower control arms, fixed length sway bar links with stud eliminator, and precision tuned Outback Kitters 2.5" remote reservoir with adjuster shocks. In the rear this kit utilizes heavy duty cast steel blocks, longer u-bolts, and a matching set of Outback Kitters 2.5" remote reservoir with adjuster shocks.
Pro-Ride Coil Springs A pair of full-length, diesel-specific, progressive rate Pro-Ride coil springs are supplied to provide the correct lift height and smooth, predictable ride across various terrains. Manufactured from high tensile steel, our direct OE replacement coil springs are engineered with properly sized wire diameter. This results in maximum reliability without premature coil bind.
HD Adjustable Track Bar Maintain proper handling and steering geometry with the BDS high strength adjustable track bar that allows you to recenter the front axle at a variety of lift heights. Built from 1-3/8" solid steel stock, the track bar comes pre-assembled with bushings and is ready to bolt into the factory mounting points.

BDS wheel positioning guidance
Meeting a backspacing limit does not guarantee wheel fitment. Check wheel diameter, tyre size, brake clearance, suspension and all kit-specific requirements.
Results are approximate. The calculation allows an additional 1 inch for the wheel's two rim flanges (approximately 0.5 inch each). Actual flange dimensions vary between wheels.
Understanding wheel measurements
What is wheel backspacing?
The distance from the wheel mounting surface to the outermost edge of the inner rim flange, measured in inches.
What is wheel offset?
The distance between the wheel mounting surface and the wheel centreline, measured in millimetres.
Why does wheel width matter?
Two wheels with the same backspacing but different widths will have different offsets.
Why does BDS specify backspacing?
It helps position the wheel relative to steering and suspension parts, but is only one part of confirming fitment.
