4 Inch Lift Kit w/ 4-Link | Ram 3500 (19-23) 4WD | Diesel

Built for diesel Ram 3500 owners who demand 4 inches of lift without compromising steering geometry or driveline angles — this BDS 4-Link conversion kit pairs a purpose-built front suspension with rear blocks to add clearance for up to 37" tires while preserving factory driveshaft use. The engineered caster correction and transfer case re-indexing keep your truck handling sharp, not sketchy.

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

• Pro-Ride dual-rate coil springs — diesel-specific tuning delivers the correct 4" lift height with a smooth, predictable ride across gravel, pavement, and rough terrain.
• 4-Link conversion with 1/4" steel brackets — replaces factory stamped steel radius arms with heavy-duty upper and lower control arms, optimizing suspension geometry for better handling and added strength while limiting caster change throughout wheel travel.
• Forged drop pitman arm and track bar bracket — steering correction hardware that minimizes steering angle and keeps front axle recentered through suspension travel.
• Sway bar relocation, brake line brackets — ensures proper clearance and safe brake function at ride height.
• Transfer case re-indexing ring and new transmission crossmember — allows use of the factory front driveshaft without binding or angle issues.

Out back

High-strength fabricated lift blocks deliver 2" of rear height, paired with longer u-bolts and your choice of NX2 Nitro or FOX shocks for a balanced stance and durable suspension package.

Pick your shocks

• BDS NX2 Nitro Series — comfortable daily driver performance, IFP design resists fade under load.
• FOX 2.0 Performance Series — responsive tuning for mixed on-road and light off-road duty, factory-grade reliability.
• FOX 2.5 Performance Elite — premium adjustable damping and external DSC adjusters for fine-tuned comfort and control in any condition.

Important notes

• Maximum tire size: 37" — verify backspacing and offset with your wheel choice to avoid suspension or body contact.
• Transfer case re-indexing is required and included; this allows factory driveshaft use and prevents binding at ride height.
• Kit is designed for diesel-powered Ram 3500 4WD models (2019–2023); verify model year and drivetrain before ordering.
• Rear block lift does not require driveshaft modification; front 4-Link geometry change is minimal and corrected by drop pitman and track bar hardware.
