6 Inch Lift Kit | Dodge Ram 2500 (2009-2013) 4WD Gas | Block Kit | 4 Inch Axle | NX2 Nitro Series | BDS Suspension

Rear lift is achieved via cast iron tapered block kit designed for a 4 inch rear axle. Blocks are offset to restore axle position and correct pinion angle, reducing axle wrap for a more controlled feel. Paired with NX2 Nitro Series shocks featuring a nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, dual-welded ends, a 1-3/8-inch high-flow piston, and silver powder coat finish.

Overview

This 6-inch lift kit from BDS Suspension is designed for the 2009–2013 Dodge RAM 2500 4WD gas-powered truck. The kit improves stance, performance, and capability, providing clearance for up to 36-inch tires. BDS engineered new lower control arms that are longer than stock to rotate the axle for proper alignment, along with a relocation mounting bracket to flatten the upper control arm angle and maintain factory handling characteristics.

Up front, the kit includes gas-specific Pro-Ride coil springs, all four control arms plus a relocation bracket, a forged drop pitman arm, a track bar bracket for steering correction, bump stops, sway bar links, and precision-tuned shocks. The rear configuration is available with either heavy-duty cast steel lift blocks with longer u-bolts, or replacement multi-leaf progressive rate leaf springs — each paired with a matching set of shocks.

Pro-Ride Coil Springs

A pair of full-length, gas-specific, progressive rate Pro-Ride coil springs provide the correct lift height and smooth, predictable ride across various terrains. Manufactured from high-tensile steel with properly sized wire diameters, these direct OE replacement coil springs deliver maximum reliability without premature coil bind.

Steering Correction

A forged drop pitman arm minimizes the steering angle once the vehicle is lifted. It is paired with a heavy-duty track bar drop bracket to keep steering components in phase throughout suspension travel while recentering the front axle.

Features

• Tubular short arms improve strength, handling, and caster control
• Heavy-duty control arm brackets maintain proper suspension geometry
• Front high-strength progressive rate coil springs for improved ride on any terrain
• Front track bar relocation bracket to re-position the axle
• Forged drop pitman arm to correct steering angles
• Front sway bar correction to maintain handling performance
• Choice of NX2 Nitro Series or FOX 2.0 Performance Series shocks for improved ride and off-road performance

Important Notes

• Measure rear axle tube before ordering. Some 4-inch axle models with dual overloads will require u-bolt #4068.
• Power Wagon applications require sway bar link kit #122401. The Power Wagon has a 2-inch taller ride height, so net lift gain will be 4 inches.
• If driveline vibration occurs, order transfer case index kit #122801 or #122802.
• Rear brake lines included with kit #102009 will not fit 2012–2013 models.
