2005–2022 Ford Super Duty F-250/F-350/F-450 Adjustable Four-Link Kit with Face Plates, 2.5–10 in. Lift
2005–2022 Ford Super Duty F-250/F-350/F-450 Adjustable Four-Link Conversion Kit with Face Plates, 2.5–10 in. Lift
Recenter your axle. Fine-tune caster. Get sharper control from your lifted Super Duty.
Upgrade your 2005–2022 Ford Super Duty F-250, F-350, or F-450 with an adjustable four-link conversion kit built for lift heights from 2.5 to 10 inches. This system helps restore axle positioning, improve caster adjustment, reduce tire rubbing, and deliver more controlled handling on the street or trail.
Why This Four-Link Conversion Stands Out
- Adjustable control arms: Fine-tune caster angle and axle centering for your specific lift height.
- Face-plate construction: Steel face plates provide a strong foundation for the conversion setup.
- 2.5–10 inch lift compatibility: Built for lifted Super Duty trucks from mild builds to serious height.
- Improved steering geometry: Proper adjustment helps reduce tire rubbing and improve steering response.
- Polyurethane bushings: Durable bushings support long-term street and off-road use.
- DOM tubing and bushing ends: Strong, serviceable components for a hard-working suspension.
- Mostly factory hardware: Designed for a straightforward installation.
- No drilling or welding required.
- Built by Apoc Industries.
What’s Included
- 2 upper control arms with steel face plates
- 2 lower control arms with steel face plates
- Four-link conversion bracket
- Heavy-duty polyurethane bushings
- DOM tubing with bushing ends
- Mostly factory hardware
- Grease fittings
- Installation instructions
Installation Details
- Estimated install time: 3–4 hours
- Tools required: Basic hand tools, jack, and jack stands
- Installation: No drilling or welding required
- Setup: Adjust the control arms to match your lift height before installation
- After installation: A professional alignment is recommended
Important: This kit requires at least 2.5 inches of lift. Set control-arm length to match your lift height for proper suspension geometry. If you are unsure of your exact lift measurement, confirm it with your lift kit manufacturer before ordering.
Choose Your Finish
Available options include Raw Metal, Satin Black, White, Red, Blue, Yellow, Green, and Silver. The finish selector identifies the overlay color, while the arms remain black where specified by the option.
Fitment
Designed for 2005–2022 Ford Super Duty F-250, F-350, and F-450 trucks with 2.5–10 inches of lift. Confirm your exact truck configuration and suspension setup before ordering.
Upgrade your Super Duty with the adjustability, axle control, and fitment range a serious lifted build demands.

Complete Kit – Ready to Install:
Engineered 4-Link Conversion for Your Super Duty
Apoc’s 4-Link Conversion Kit upgrades your Ford Super Duty’s suspension with enhanced control, smoother ride quality, and precise caster correction for lifted setups. The heavy-duty frame brackets bolt directly into the factory radius arm mounts—no cutting, welding, or drilling required. Each kit includes four extended-length control arms—two uppers and two lowers—fully assembled and ready to install. The kit also features upgraded axle-side cam eccentric bolts, giving you the ability to fine-tune caster easily—a feature never offered from the factory. Built for strength, simplicity, and serious performance.
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
Ford Superduty 4 Link Coversion FAQ's
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..
A: Yes. Unlike the factory setup, the Apoc 4-Link Conversion Kit includes upgraded axle-side cam eccentric bolts, giving you full control over caster adjustment—a feature Ford never offered. Once your control arms are set to the correct length, these cams allow precise fine-tuning of caster, whether you're doing it yourself or having it aligned professionally. It’s a smarter, more flexible setup designed to improve drivability and alignment accuracy.
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, welding, or drilling is required. The frame brackets are engineered to bolt directly into the factory radius arm mounts using existing holes, making installation clean, fast, and hassle-free. It’s a true bolt-on upgrade designed for maximum strength with zero guesswork.
