6 Inch Lift Kit w/ 4-Link | Ram 3500 w/ Rear Air Ride (19-24) 4WD | Diesel

Built for Ram 3500 diesel owners who demand 37-inch tire clearance without sacrificing ride quality or driveline geometry. This 6-inch 4-Link lift kit from BDS gives you the stance, performance, and capability to run bigger rubber while keeping your truck planted and predictable. The 4-Link control arm conversion corrects caster and improves handling, while diesel-specific Pro-Ride coil springs deliver smooth, tuned-in performance on any terrain.

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

• Diesel-specific Pro-Ride coil springs — full-length units tuned to deliver the correct lift height and smooth, predictable ride across varied terrain.
• 4-Link control arm conversion — high-strength 1/4-inch steel brackets with upper and lower control arms correct axle positioning and limit caster change throughout wheel travel, optimizing geometry for better handling and added stability.
• Forged drop pitman arm and track bar bracket — steering correction components that keep your front end dialed in at 6 inches of lift.
• Sway bar relocation and brake line brackets — essential hardware for proper fitment and function.

Out back

High-strength steel lift blocks paired with add-a-leaf springs keep the rear planted. Heavy-duty air bag spacers and new U-bolts work with the factory rear air ride system to maintain its OE comfort and load-handling capability — all while fitting 37-inch tires.

Pick your shocks

• BDS NX2 Nitro Series — smooth, comfortable daily driver with a nitrogen charge for consistent performance. Available on 6-Bolt or 8-Bolt configurations at $2,625.05.
• FOX 2.0 Performance Series — tuned for responsive handling and terrain feedback. Choose 6-Bolt at $3,225.05 or 8-Bolt at $3,185.05.

Important notes

• This kit is engineered for Ram 3500 trucks with factory rear air ride suspension (model years 2019–2024, 4WD diesel only).
• Transfer case indexing is required at this lift height to maintain proper front driveline operating angle; an ARP-studded indexing ring and high-clearance transmission crossmember are included.
• The factory front driveshaft can be retained with the indexing ring installed — no custom shaft required.
• Maximum tire clearance is 37 inches; larger sizes risk suspension interference and drivetrain damage.
• Choose 6-Bolt or 8-Bolt configuration to match your wheel mounting pattern.
