The Best Sub-Frame Connectors. The J&M Standard Length Subframe Connectors are a long 66 inches for expanded weld area. They also stand 50% higher than most competitors for more strength. They follow the tight contours of the Mustang’s floor pan when welded in place to provide increased ground clearance and ultimate strength.

Weld-In Design, High-Strength Steel. J&M designs the Standard Length Subframe Connectors to provide real help for the rigidity and integrity of your Mustang’s chassis. That’s why you get 66” of high-strength steel, shaped exactly to the Ford’s floor pan. J&M leaves the connectors unfinished so you can paint them any color to match your ride.

Weld-In Engineering. Unlike other bolt-in connectors, the J&M Subframe Connectors are designed to be welded into position. Thanks to the increased build area provided for welding, you get even greater performance. Welding them in might require a professional for installation, but the results are definitely worth it.

Application. The J&M Bare Finish Standard Length Subframe Connectors fit 1979-2004 Ford Mustangs.

    J M Full Length Subframe Connectors- Bare

    To start off, I loved the quality of these. Once welded in, I took the stang for a ride and you can completely tell how much stiffer the ride is. Not near as much body flex and body roll throughout corners. I also liked how the ends are sealed off so no debris or water can get into them and begin to rust them out. I do wish it had the seat brackets. I powder coated mine black to help protect the outside finish. Easy, short install if you have the knowledge and equipment to weld them in yourself. I definitely recommend these to anyone wanting subframe connectors.
