4 Inch Lift Kit w/ 4-Link | Ram 3500 (13-18) 4WD | Gas

Built for Ram 3500 gas owners who want 4 inches of front lift, better handling geometry, and room for 35-inch tires — this BDS 4-Link conversion kit transforms your truck's suspension into a geometry-corrected, stronger platform. The 4-Link converts factory stamped radius arms to adjustable control arms that preserve caster angles through the full range of travel, while forged steering corrections keep your steering feel crisp and centered after the lift.

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

• BDS Pro-Ride Coil Springs — gas-specific, progressive-rate springs tuned for your truck's weight and deliver smooth, predictable ride on road and trail.
• 4-Link Control Arm Conversion — bolt-on upgrade with 1/4-inch steel brackets and HD upper and lower control arms that correct axle positioning and limit caster change throughout suspension travel, improving handling and stability.
• Forged Drop Pitman Arm & Track Bar Bracket — steering geometry correction that minimizes steering angle and keeps components in phase through suspension travel, recentering the front axle.
• Bump Stops & Brake Line Brackets — complete hardware to protect geometry and keep brake lines secure under articulation.

Out back

High-strength fabricated lift blocks with longer u-bolts complete the rear, available in 2-inch or 3-inch heights depending on your variant. Pair with your choice of shocks for a balanced ride.

Pick your shocks

• BDS NX2 Nitro Series — smooth, responsive daily driver shocks that handle stock and mildly modified trucks. Great value for the money.
• FOX 2.0 Performance Series — velocity-sensitive damping adapts to trail abuse and highway cruising. Mid-range durability and tuning.
• FOX 2.5 Performance Elite — adjustable external reservoirs, bypass circuits, and three-stage damping for serious off-road and high-speed performance.

Important notes

• This kit is engineered for 2013–2018 RAM 3500 gas models only — not compatible with air-ride or diesel variants.
• Maximum tire clearance is 35 x 12.5 inches; larger tires will require trimming or rubbing.
• Front lift is 4 inches; rear options are 2 inches or 3 inches, so check your variant before ordering to match your desired ride height.
• 4-Link conversion optimizes geometry for better handling characteristics and stability.
