GM HD 2001-2010 05+ Ford Super Duty Radius Arm Kit

Pricing: $950.00



This is our WFO '05-'12 Ford Superduty Radius Arm Link Kit. We offer two different styles of links for the '05+ Ford Superduty Axle: 4 link and Radius Arm. We use both styles of links when we install Straight Axle Swaps on Duramax Trucks with the '05-'12 Superduty Axle depending on the lift height of the truck. These links are designed to work with our Duramax Crossmember (see related items) however, for Non-Truck applications you could use our universal under the frame link mounts for your custom application.

The Radius Arm setup is for anyone running less than 8” of lift. 

The lower links are made out of 2” x .250 wall DOM and the upper links are made out of 1.75” x .250 wall DOM. The large clevis ends on our links will bolt directly over the '05-'12 Ford Superduty Rubber Axle Mounts. For the upper arm we provide 7/8” x 3/4” heim joints.

The tube inserts and upper link tabs are welded onto the links in the correct location. These are now complete and ready to install.

These links ship raw metal.

This kit includes:

  • Pair of lower and upper links
  • Two, Duroflex Joints 
  • Two, 7/8" x 3/4" heim joints
  • Grade 8 hardware for the Duroflex Joints and the heim joints

If needed, we also offer the metric bolts to mount the links to the OEM rubber axle mounts. These are sold as a set of four and include new washers and nylocks. See Related Products below.
