Synergy 2005+ Ford Super Duty F-250 / F-350 Heavy Duty Steering Kit

Upgrade your Ford Super Duty’s steering performance with confidence with the Synergy 2005+ Ford Super Duty F-250 / F-350 Heavy Duty Steering Kit. Engineered to deliver immediate improvements in steering feel, responsiveness, and long-term durability in a true bolt-in format without requiring any modifications. Even better, it works seamlessly with OEM wheels and tires! No need to change a thing to enjoy the benefits of increased strength and stability.

At the heart of the system is our high-strength tie rod, precision CNC-formed from 1.75” heat-treated 4130 chromoly for exceptional toughness in demanding conditions. The drag link is built from USA-made 1.5” 1026 DOM steel tubing that allows you to retain compatibility with the factory steering stabilizer mount - giving you the flexibility to run stock or upgraded stabilizers as you see fit.

For those looking to take steering performance even further, this kit is fully compatible with our line of upgraded stabilizer kits. Choose from single or dual configurations, with options for both stock and low-mounted tie rod stabilizers, so you can dial in the setup that works best for your truck’s specific needs—whether you’re towing, daily driving, or heading off-road.

Pro Tip: Pair this steering kit with our Heavy Duty Adjustable Track Bar for superior ride control and quality!
