4 Inch Lift Kit w/ 4-Link | Ram 3500 (13-18) 4WD | Diesel

Built for Ram 3500 diesel owners who want serious lift without sacrificing ride quality or geometry — this 4-inch front / 2–3-inch rear kit delivers the stance and tire clearance you need, plus a 4-Link conversion that preserves proper suspension geometry and steering response. You get diesel-tuned coil springs up front, caster correction, and your choice of shock tier.

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, progressive-rate springs engineered for the weight and load of your 3500 diesel, delivering 4 inches of lift with a smooth, predictable ride across pavement and rough terrain.
• 4-Link Control Arm Conversion — High-strength 1/4-inch steel brackets and HD upper/lower control arms replace the factory stamped-steel radius arms, correcting axle positioning and limiting caster change throughout wheel travel for better handling and stability.
• Steering Correction Package — Forged drop pitman arm and heavy-duty track bar drop bracket keep the steering and axle in phase, recentering the front end and optimizing steering geometry after the lift.
• Bump Stops & Brake Line Brackets — Precision-engineered brackets and reinforced bumpstops manage suspension travel and protect brake lines under flex.

Out back

A high-strength fabricated lift block — 2 or 3 inches, your choice — pairs with longer u-bolts and rear shocks matched to your front package, giving you a level or slightly rake-forward stance and controlled suspension articulation.

Pick your shocks

• BDS NX2 Nitro Series — Comfort-focused, nitrogen-charged damping; the go-to for daily driving and stock-terrain use.
• FOX 2.0 Performance Series — Tuned for light off-road work; responsive compression and rebound with better control over bumps and ruts than the Nitro.
• FOX 2.5 Performance Elite — Top-tier remote-reservoir shock with DSC (Dual Spin Compression) adjusters; dialed for aggressive terrain and the weekend warrior who wants precision tuning at their fingertips.

Important notes

• This kit supports up to 37 × 12.5 tires — confirm your wheel offset and backspacing to ensure fitment within the new fender envelope.
• Fits only non-air-suspension Ram 3500 models (2013–2018); does not work with factory air-ride suspensions.
• The 4-Link conversion and caster-correction geometry are core to this kit — they cannot be removed or swapped for the factory radius arms without compromising the handling gains.

Why customers pick this at Road Runner

• Corrected geometry out of the box — The 4-Link conversion and drop pitman/track bar assembly handle caster correction so you don't lose steering response or eat through tires prematurely.
• Diesel-proven springs — Pro-Ride coils are spec'd specifically for the 3500's weight; you get the right lift height with a predictable, comfortable ride.
• Full BDS warranty backed locally — We install these kits every week; if anything fails, we handle the warranty claim directly.
• Shock tiers for every budget — Start with NX2 comfort or step up to FOX 2.0 / 2.5 without changing the core lift or geometry.
• Mount and balance available on most trucks — Our techs specialize in BDS kits and know the tricks to get you back on the road fast.
