03-07 Dodge Dsl 6/4 LA Block w/3-1/2 ax

Built to outperform, BDS Suspension engineered a 6-inch lift kit with long arm conversion for your 2003-2007 Dodge RAM 2500 and 3500 4WD diesel powered truck that maximizes performance on and off road.

Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 37 inch Tires. BDS built the long lower control arms to reduce caster change through wheel travel which creates a more controlled feeling in the steering wheel.

This long arm long arm system retains the factory triangulation of the arms which adds to the stability of the suspension system.

Up front the lift kit includes diesel-specific Pro-Ride coil springs, all four control arms plus mounting bracket, forged drop pitman arm and track bar bracket for steering correction, bump stops, sway bar links, and precision tuned NX2 or FOX 2.0 nitrogen charged shocks.

In the rear this kit utilizes heavy duty cast steel blocks, longer u-bolts, and a matching set of NX2 Nitro or FOX 2.0 Performance 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.

Steering Correction

To optimize steering geometry once lifted, a forged drop pitman arm is used to minimize the steering angle and pair it with a heavy duty track bar drop bracket to keep them in phase through suspension travel while recentering the front axle.
