GM HD 2011-2019 '05+ Ford Super Duty Radius Arm Links 12" Lift Height

Pricing: $1,019.00


This is our WFO Radius arm kit for the 12" Straight Axle Swap on the 2011-2018 Duramax and HD trucks using a '05-'18 Ford SuperDuty axle.

The lower links are made out of  2” x .250 wall DOM.  The large clevis ends on the links will bolt directly over the '05-'18 Ford Super Duty Rubber Axle Mounts.  On the frame side, we use a Metal Cloak Duroflex joint that is 2 5/8" wide and fits perfectly in our WFO Crossmember.    

The upper links are made out of 1.75” x .250 wall DOM.  The large clevis ends on the links will bolt directly over the '05-'18 Ford Super Duty Rubber Axle Mounts. Where the upper link swings down and attaches to the lower link we provide a 7/8” x 3/4” FK heim joint.  The tabs on the lower links have been welded in the correct location on the lower links so proper caster will be achieved. 

These radius arms are complete and ready to install.  No welding required!  They are raw metal so you will need to paint or powdercoat them.       

This kit includes:

  • Pair of lower and upper links
  • Two Duroflex Joints 
  • Two 7/8" x 3/4" FK 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.  (See suggested items.)
