Features & Details

  • Full Length Subframe Connectors.
  • Eliminates Chassis Flex.
  • Weld-In Design.
  • Durable Black Powdercoat.
  • Fits All 1979-2004 Mustangs.
Renew Your Chassis. Your 1979 to 2004 Mustang will feel like new again with a set of J&M subframe connectors. Over time your chassis develops microcracks that cause it to weaken, making your Mustang feel sloppy on the road and even adding annoying rattles. Give it a fresh feel and increase responsiveness by reinforcing the frame.

Eliminates Flex. By eliminating chassis flex, none of your Mustang's power will be wasted when your chassis flexes under load. That means all of your Mustang's power will also go straight to the pavement, so you'll get the most from your mods.

Made to Last. The J&M full length subframe connectors are a weld-in design that is much stronger than bolt-in styles for performance you can rely on. Both ends are sealed to prevent damage from debris and water, and they feature a durable black powdercoat.

Application. The J&M full length subframe connectors are designed to fit 1979 to 2004 Mustangs. Sold as a pair.

Fitment: 1979 1980 1981 1982 1983 1984 1985 1986 1987 1988 1989 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 Details

    Perfect

    Installed on my 98 GT 'Vert. Huge improvement, a must have on convertibles. Before the car would shake, rattle, twist especially over rough roads. Feels like a new car now, very solid, lets the suspension do its job instead of the chassis flexing. These fit perfect and have a couple bends in them for maximum ground clearance. Great Buy!

    Good product

    On the street I didn'treally notice much of a difference, but once I hit the strip with my sticky tires the J&M's really showed themselves. I had asolutely no chassis twist like I had become to expect. My Cobra now stays straight as an arrow when I shift to second instead of torqueing to the left. Great bang for the buck product.

    Sweet!

    I had these welded on and feel a noticeable difference. I do not feel the car wobble. These helped put the power and torque on the tires, and not in the frame.

    these things stiffen up the chassis a bunch! as far as chassis stiffening this is the way to go. these make a bigger difference then strut tower braces by far.

    great product for the price

    This product is excellent for people on a budget or people who own their own welder. good quality and easy to install. took less then 3 hours to install with minimal problems. (Mostly my bent frame rails were the problem)

    Not worth it

    These connectors are not good at all. I just bought them and instantly shipped them back. Took a 30 doallr loss but that is much better then this going onto my car. Fit was right but the tube itself has many weak points through it. Every bend is just that bent it is not welded to create strength. After myself saying i dislike them took them to my mechanic to get his opinion. He looked at them and said they would not only be the hardest install he has ever done but most expenisve and pointless. If your going to get subframes go with a better brand. These are great until they would be truly tested.

    Bad

    Like cj said these are junk. Any mechanic will tell you these are not good and install will be hard.

    Great performance difficult install

    The performance aspect of the SFCs are night and day from factory. The only downside is they took some heavy modification to line up and weld.

    Good product, good price.

    Simple, easy to install (if you can mig weld). Tightens the car right up, feels solid and planted now.
