💬 Why Upgrade to a Four-Link?
The factory radius arm design on Ram 2500s can limit suspension travel, cause binding, and reduce ride quality when lifted. Our four-link kit corrects caster, reduces axle twist, and distributes load more evenly. Whether you’re rock crawling, towing, or just want a smoother ride on 37s or 40s, this upgrade delivers.

What all comes with a Ram 4 Link Conversion kits?
Complete Kit – Ready to Install:
Engineered 4-Link Conversion for Your Ram
Apoc’s 4-Link Conversion is built for complete suspension control, improved ride quality, and corrected caster angles on lifted trucks. Each kit includes two heavy-duty frame brackets that mount directly into the factory radius arm locations, requiring only one 1/2" hole drilled per side for installation. The kit comes with a full set of extended-length control arms—two uppers and two lowers—fully assembled and ready to install. Lower arms are bent for added tire clearance, allowing smooth articulation and steering with larger tires. Axle-side hardware is reused, keeping the installation clean and straightforward.
Premium Bushings – Built for Life:
Apoc Industries backs our bushings with a Lifetime Warranty for lasting confidence. We use only the highest quality polyurethane (PTMEG-based) in all Apoc products.
PTMEG polyurethane offers superior articulation and a firmer, more responsive feel — without the harshness commonly found in solid joints like heims or flex joints.
These bushings are ideal for daily driving while providing excellent durability and performance for moderate off-road use.
Adjustable Length for Precise Handling:
Apoc control arm kits are designed with flexibility in mind. They are stock length when fully collapsed and up to 2.5 inches longer when fully extended, giving you plenty of adjustability to fine-tune your truck’s suspension geometry and handling. Whether you’re leveling, lifting, or optimizing alignment, our arms provide the range needed for a perfect setup.

FAQ'S
RAM 4 link Conversion kit
A: A 4-link conversion replaces the factory radius arm setup, delivering better suspension geometry, improved ride quality, and more precise caster control—especially on lifted trucks. Unlike radius arms that limit articulation and can cause binding, a true 4-link setup allows each control arm to move independently, reducing stress on bushings and increasing flex. The result is smoother handling, better tire contact, and a more stable, confident ride—on the road or under load.hts.
At Apoc Industries, we understand that every suspension change impacts your vehicle’s geometry. That’s why we provide detailed installation instructions, including caster correction measurements tailored to a variety of lift and leveling heights. Whether you’re adding a small leveling kit or a full suspension lift, our guides ensure you have the correct specifications to dial in your alignment for maximum drivability, tire life, and performance.
Taking the guesswork out of your setup means better results — and a better ride..
Yes, you can continue using your factory alignment bolt. Its eccentric design allows for easy fine-tuning of caster angles once the control arms are set to the correct length. This ensures a smooth and precise alignment process, whether you’re adjusting it yourself or having it dialed in by a professional shop.
Our components are engineered to work seamlessly with your existing hardware, saving you time and keeping installation straightforward.
For PTMEG (polytetramethylene ether glycol) polyurethane bushings, the best grease is a silicone-based lubricant with PTFE (polytetrafluoroethylene) additives. Here’s why and what to consider:
Why Silicone-Based with PTFE?
: PTMEG polyurethane is resistant to petroleum-based products, but silicone-based grease is preferred as it won’t degrade the material and is explicitly recommended for polyurethane bushings.Tackiness
: PTFE additives lower the coefficient of friction and are waterproof, ensuring long-lasting lubrication and quiet operation.
: Silicone-based grease repels water, protecting bushings from corrosion and maintaining performance in wet conditions.
A: No cutting or welding is required. Installation is simple—just drill one 1/2" hole on each side behind the factory radius arm mount. The frame brackets are designed to bolt directly into the stock location, making this a clean and straightforward upgrade.
