2003-2007 Dodge Ram 2500 / 3500 4wd Long Arm Upgrade Kit
2003–2007 Dodge Ram 2500 / 3500 4WD Long Arm Upgrade Kit
Lift requirement: 3–10 inches of lift. This kit will not work with less than 3 inches of lift.
Short factory control arms have a hard limit. As lift height increases on a 2003–2007 Ram 2500/3500, the stock arms run out of geometry — caster goes deeply negative, the axle shifts forward more than drop brackets can correct, and alignment shops can only chase the problem rather than fix it. The solution is longer arms with genuine adjustability.
The Apoc Industries Long Arm Upgrade Kit replaces the factory short arms with extended heavy-wall DOM tubing arms that have the range to re-center the axle and restore proper caster at higher lift heights where the stock arms simply can't reach. Each arm is independently adjustable so you can dial in caster and axle position separately.
Fits 2003–2007 Dodge Ram 2500 and 3500 (4WD, solid front axle). Built in the USA.
⚠️ 4WD solid front axle only. Requires 3–10 inches of lift; not compatible with less than 3 inches of lift.

What all comes with a Dodge Long arm kits?
Complete Kit – Ready to Install:
Apoc Long Arm Kits are engineered for full suspension control, improved ride quality, and better caster angles on lifted trucks. Each kit includes two heavy-duty frame brackets with all required hardware and a complete set of extended-length control arms—two uppers and two lowers—fully assembled and ready to install. The lower arms are bent for added tire clearance, allowing smooth articulation and turning with larger wheels and tires. Axle-side hardware can be reused or upgraded as needed, making installation straightforward and secure.
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
Dodge Adjustable control Arms
A: Long arm kits improve ride quality, suspension geometry, and caster angles on lifted trucks. The extended control arms reduce binding and allow smoother articulation, better tracking, and more stable handling—especially at higher lift heights.
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: Yes. The frame brackets are a permanent upgrade and require cutting and drilling for proper installation. You’ll also need to remove the factory lower control arm brackets on the frame side to make room for the new long arm mounts. All required hardware is included, and detailed instructions are provided to make the process as straightforward as possible.
