BDS 6 Inch Long Arm Lift Kit | 2008 Dodge Ram 2500/3500 4WD Gas | Block Kit | 4 Inch Axle | FOX 2.0 Performance Series

Configured with a Block Kit for the 4 Inch rear axle and FOX 2.0 Performance Series shocks. The rear block kit uses cast iron blocks tapered for correct pinion angle with an offset steel pin to restore axle position. FOX 2.0 shocks feature a 2-inch impact extruded aluminum body, internal floating piston (IFP) monotube design, CNC machined 6061-T6 aluminum mounting ends, and a massive 5/8-inch hard chrome plated heat-treated alloy steel shaft with application-specific valving.

Overview

BDS Suspension engineered this 6-inch lift kit with long arm conversion for the 2008 Dodge Ram 2500 and 3500 4WD gas-powered truck to maximize performance on and off road. Designed to improve stance, performance, and capability, this kit includes everything necessary to lift your truck with clearance for up to 37-inch tires. The long lower control arms are built to reduce caster change through wheel travel, creating a more controlled steering feel, while the long arm system retains the factory triangulation of the arms for added suspension stability.

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

Features

• Tubular long arms reduce caster change and create a more controlled feel on and off road
• Heavy duty control arm brackets maintain proper suspension geometry
• Front high-strength progressive rate Pro-Ride coil springs for a smooth ride on any terrain
• Gas-specific Pro-Ride coil springs manufactured from high tensile steel with properly sized wire diameter for maximum reliability without premature coil bind
• Front track bar relocation bracket to re-position the front axle
• Forged drop pitman arm to correct steering angles once lifted
• Heavy duty track bar drop bracket to keep steering geometry in phase through suspension travel
• 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
• Rear lift option available as cast iron block kit or multi-leaf progressive leaf springs

Specifications

• Lift Height: 6 inches
• Tire Clearance: Up to 37 inches
• Rear block kit: Cast iron construction, tapered for correct pinion angle, offset steel pin to restore axle position
• Rear leaf springs: Multi-leaf progressive design, maintains factory payload weight ratings
• Rear axle options: 3-1/2 inch or 4 inch diameter (measure before ordering)
• NX2 Nitro Series shocks: Nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, dual-welded ends, 1-3/8-inch high-flow piston, self-lubricating seals, silver powder coat finish
• FOX 2.0 Performance Series shocks: 2-inch impact extruded aluminum body, internal floating piston (IFP) monotube design, CNC machined 6061-T6 aluminum mounting ends, 5/8-inch hard chrome plated heat-treated alloy steel shaft, race-developed high-flow piston, application-specific valving, clear anodized finish

Installation

• Estimated Time: 6–8 hours
• Difficulty: Moderate
• Tools Required: Step Drill Bit, Drill / Bit Set, Pitman Arm Puller, Welding Equipment

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.
• If your truck has had the steering gear box changed and the sector shaft diameter measures approximately 1-1/2"–1-5/8", you will need to add part #BDS082404 to your kit.
