3 Inch Lift Kit w/ Radius Arm | FOX 2.5 Coil-Over Conversion - Performance Elite | Ram 3500 (19-24) 4WD | Diesel

Built for diesel 3500 owners who want 3 inches of front lift, coil-over precision, and the ability to fit 35-inch tires — this BDS Radius Arm kit replaces the factory setup with FOX 2.5 Performance Elite coilovers up front and a 2-inch rear block, giving you better articulation, plush damping, and the clearance to upgrade your rolling stock.

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 Coil-Over Conversion Kit with FOX 2.5 Performance Elite Coilovers — replaces the factory coil springs with a fully valved FOX system engineered for the 3500's weight and geometry. Delivers precision damping and ride comfort on or off pavement.
• BDS Radius Arms — heavier-duty than OE, these improve articulation and reduce bind under load while preserving driveline geometry.
• 3-inch front lift height — achieved through the coil-over conversion, not a spacer or block.

Out back

2-inch rear block with FOX Performance Elite shocks standard. Choose between rubber bump stops or FOX 2.0 Hydro Bump Stops (the hydro option adds compliance and control on hard landing). Blocks are available for both 6-bolt and 8-bolt rear axles; overload leaf springs optional depending on your payload needs.

Important notes

• Max tire size: 35 x 12.5 — stay within this window to avoid suspension or chassis interference.
• OE wheel fitment: Factory wheels may require backspacing review before installation. Confirm offset and backspacing with our team.
• Transfer case re-indexing: Driveline geometry has been corrected in the design, but the transfer case may need re-indexing to factory specs post-install — ask your installer.
• ABS and factory sensors: If your 3500 has electronic suspension or ABS sensors tied to suspension height, they may need recalibration after lift installation.
• Diesel-specific: This kit is engineered for 2019–2024 RAM 3500 diesel 4WD (includes Power Wagon, Tradesman, SLT, Big Horn, Laramie, and Laramie Limited trims).

• Our team knows the 3500 diesel inside-out — we'll confirm your axle config, wheel fitment, and any sensor recalibration before you leave.
