6" 2025-2026 Dodge Ram 2500 4WD (w/diesel engine) 4-Link Lift Kit by BDS Suspension

BDS 2136H / 2136FS 6" 4-Link Lift Kit for Ram 2500 diesel trucks improves suspension geometry, ride quality, and off-road capability while maintaining excellent on-road comfort and drivability. Designed specifically for diesel applications, this extended travel system provides clearance for up to 37" tires while correcting driveline angles and increasing suspension performance for demanding use both on and off the road.

At the core of this system is a heavy-duty 4-link front suspension that replaces the factory control arms to properly position the axle and significantly reduce suspension bind throughout travel. This design maintains consistent caster and pinion angles, improving straight-line stability, steering return-to-center, and braking control. Pro-Ride coil springs are engineered to support the added weight of the diesel platform while delivering a smooth and controlled ride. A transfer case indexing ring optimizes driveline angles and increases suspension droop, while a heavy-duty track bar bracket ensures proper axle centering and steering alignment.

Shock options allow further customization of ride quality and terrain capability. BDS NX2 Nitro shocks provide a comfortable, budget-friendly ride for everyday driving. FOX 2.0 Performance Series shocks deliver consistent, fade-free damping with improved control. FOX 2.5 Performance Series HTO shocks add increased oil capacity and position-sensitive rebound control, while FOX 2.5 Performance Elite shocks with DSC adjusters offer independent high- and low-speed compression tuning for maximum performance and versatility in aggressive conditions.
