3 Inch Lift Kit w/ Radius Arm | FOX 2.5 Coil-Over Conversion - Performance Elite | Ram 3500 (13-18) 4WD | Diesel

Built for Ram 3500 diesel owners who demand 3 inches of lift without compromising ride quality or durability. This BDS Radius Arm Lift Kit pairs a FOX 2.5 Coil-Over Conversion up front with a rear block lift, letting you run up to 35×12.5 tires while preserving your truck's geometry and driveline angles. It's the smart choice for owners who tow, haul, and want controls that feel planted on pavement and trail alike.

What you get up front

• BDS Radius Arms — Heavy-duty units that improve articulation and leverage geometry while keeping caster angles neutral for balanced steering feel.
• FOX 2.5 Coil-Over Conversion — Replaces your factory coils with a modern independent setup tuned for both highway comfort and off-road compliance. Damping adjustability lets you dial in your ride preference.

Out back

FOX Performance Elite shocks handle the rear on a 2-inch block lift, keeping the truck stable under load and soaking up bumps on rough terrain without that clunky, disconnected feel of a traditional block-only setup.

Pick your shocks

• Rubber Bump Stop — Standard front bumpstop protection for daily driving and moderate impacts.
• FOX 2.0 Hydro Bump Stop — Hydraulic compression control that fires when you hit hard landings or big impacts, adding an extra cushion of progressive resistance without affecting normal suspension travel.

Important notes

• Maximum tire size: 35×12.5. Larger tires will contact body or suspension components.
• This kit is engineered for 2013–2018 Ram 3500 4WD diesel models without air suspension. If your truck has air-ride, confirm fitment before purchase.
• Driveshaft angle is preserved by the radius arm geometry and block-lift combination, protecting your U-joints and transfer case from stress.
• Front bumpstop selection (rubber vs. hydraulic) affects the feel under extreme compression — choose based on your duty cycle (towing, rock crawling, daily).
