4" 2025-2026 Dodge Ram 2500 4WD 4-Link Lift Kit by BDS Suspension

BDS 2138H / 2138FS 4" 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 system provides clearance for up to 37" tires while correcting driveline angles and increasing suspension travel for confident performance in any environment.

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 dramatically reduce suspension bind throughout travel. This design maintains consistent caster and pinion angles, improving steering stability, return-to-center, braking control, and overall ride quality. Pro-Ride coil springs are tuned to support the added weight of the diesel platform, delivering a smooth, controlled ride whether on the highway, towing, or off-road. A forged adjustable track bar ensures proper axle centering, while the included transfer case indexing ring corrects driveline geometry and allows for increased suspension droop and improved off-road performance.

Shock options allow further customization of ride quality and performance. BDS NX2 Nitro shocks offer a comfortable, budget-friendly ride for daily driving. FOX 2.0 Performance Series shocks provide consistent, fade-free damping with improved off-road 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 deliver top-tier performance with independent high- and low-speed compression tuning for maximum versatility on any terrain.
