6 Inch Lift Kit | Long Arm | Dodge Ram 2500/3500 (03-07) 4WD | Gas

Built for Ram 2500/3500 owners who want the commanding stance and tire clearance of a 6-inch lift without sacrificing ride quality or handling. This BDS long-arm kit delivers genuine geometry correction — upper and lower control arms maintain proper caster and suspension geometry as you climb. You get a full 6 inches of height, max tire clearance for 37-inch rubber, and the driveline stays centered and square.

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

• Long-arm upper and lower control arms — geometry-corrected to maintain factory caster angles and suspension kinematics at ride height.
• Front coil springs — engineered for 6-inch lift and matched load capacity.
• Front sway bar links — extended for proper geometry and angle.
• Bump stops — repositioned to accommodate full suspension travel.

Out back

Choose between a block kit (solid, straightforward lift) or leaf springs (adds compliance for rough terrain). Both options pair with your choice of 3-1/2-inch or 4-inch axle for rear-end geometry that matches your front correction.

Pick your shocks

• BDS NX2 Nitro — comfortable daily driver feel, tuned for on-road manners and light off-road duty. Great value for the price.
• FOX 2.0 Performance Series — adjustable compression and rebound damping, designed for aggressive trail work and faster rock crawling without sacrificing highway composure.

Important notes

• Long-arm geometry is engineered for 2003–2007 Ram 2500/3500 4WD gas engines only. Not compatible with diesel engines in this model range.
• Maximum tire size is 37 inches with proper backspacing and offset; verify wheel fitment before purchase.
• Transfer case may require re-indexing depending on block height and driveshaft angle; BDS provides guidance and our techs handle this during install.
• Factory disconnecting sway bar (if equipped) may need modification or bypass; we confirm fitment at scheduling.

Why customers pick this at Road Runner

• BDS long-arm kits are backed by a lifetime warranty on welds and structural components — we handle any issues locally.
• Our techs install these every week; we know the tight points, the time-savers, and how to get geometry spot-on.
• You get real geometry correction, not just bolted-on height — your truck handles like a truck, not a pogo stick.
• One-day turnaround on most installs, so you drive out lifted the same day.
• We stock block and leaf-spring variants, plus both shock tiers — no waiting for backorders.
