Upgrade your Mustang’s chassis with a set of TommyZee’s Racefab weld-in subframe connectors, designed specifically for 1965–1970 Mustang coupes and fastbacks. These are not bolt-on gimmicks—these are precision-fit, high-performance connectors that significantly improve structural rigidity and allow your suspension upgrades to work as intended.
⚠️ Not compatible with Mustang convertibles.
Why These Are the Best:
Hug the floorpan tightly – no loss in ground clearance
Do not hang lower than the factory front framerails
Weld-in design for maximum strength and effectiveness (Bolt-ons don’t offer the same level of rigidity)
Built for Strength and Fitment:
1.75" diameter x .095" wall mandrel-bent round tubing
Fully MIG welded in a precision jig for straightness
Gusseted and braced for maximum structural integrity
Extend 8.5" up the rear framerails
Wrap 4.5" around the front framerails
