Pro Form Fab 17-22 Super Duty F250/350 4 Link Upgrade

Enhance the performance and durability of your Ford Super Duty with Pro Form Fab's Heavy Duty Tubular 4 Link Upgrade Kit. This innovative kit is designed to work seamlessly with stock trucks and up to 12 inches of lift, offering a superior alternative to the original radius arm setup. The kit is built to be a direct bolt-on solution, using the existing radius arm frame brackets along with additional brackets provided in the kit. This upgrade provides improved ride quality and driveability by introducing two-axis pivot points at the frame, allowing the axle to travel straight up and down without twisting, as compared to the single-axis radius arm setup.
  • Seamless Installation: With its bolt-on design, this 4-link kit is easy to install, minimizing downtime and maximizing performance.
  • Enhanced Ride Quality: Experience a smoother, more predictable ride with this upgraded suspension setup.

Customizable and Durable Design

Our 4-link upgrade kit is available in fixed length and adjustable versions, catering to various lift requirements. Fixed length arms are available in four sizes, ensuring the axle remains centered at the corresponding lift level. The arms incorporate 5-6 degrees of caster into their length and are built with high-density polyurethane bushings and DOM sleeves for durability and reliability. This design choice guarantees a long-lasting and robust performance.
  • Custom Fitment: Our fixed length arms are designed to fit specific lift requirements, providing a precise fit for your vehicle.
  • Quality Components: High-density polyurethane bushings and DOM sleeves ensure a strong and stable suspension system.

Convenient and Easy to Use

We understand the importance of timely delivery, which is why all kits are built to order. Please allow 8-10 business days for the raw or black powder-coated versions to ship. For a custom finish, we offer a wide range of color options to choose from, with the option to match any color from the Prismatic Powders catalog. We provide high-quality zinc coated Grade 8 hardware, including locking washers, for a fast and easy installation. With detailed step-by-step instructions, the average installation time for this kit is just 45-60 minutes, ensuring a hassle-free upgrade.
  • Build to Order: Enjoy the convenience of customizing your kit to fit your specific needs.
  • Quality Hardware: Our zinc coated Grade 8 hardware ensures a secure installation with no worries of corrosion.
