Whether your Mustang only gets driven to the grocery store or driven hard on the road course or drag strip, every 79-04 Mustang needs subframe connectors!

Steeda's full length subframe connectors are the best full length subframe connectors available for your 1979-2004 Mustang. Perfect for daily drivers, or serious cars with high horsepower, sticky tires or competition suspension.

Not only will Steeda full length subframe connectors provide unmatched strength, but will save you time in installation over other brands!

Steeda starts with beefy 1.5 x 2 x. 083 square tubing that spans the full length of the floor pan providing unmatched chassis rigidity, improved handling, and improved ride quality with reduced impact harshness.

Our full length subframes are reinforced at each bend and include Steeda's exclusive torque box reinforcing plate for the strongest attachment possible to the rear subframe for maximum effectiveness.

Steeda Full length subframe connectors also feature a one-piece reinforced seat bolt cross brace. Some subframe cross braces have 8 individual gussets which must be carefully positioned and welded on. Other other kits use no reinforcements at all in their cross braces. Steeda's cross braces have reinforcing gussets built-in, for greater strength with less welding.

Other full length subframe connector designs do not attach all the mounting point plates to the connector, leaving you to weld them during installation adding time and complexity. Steeda full length subframe connectors come with all mounting point tabs pre-welded to the subframe connector. Another Steeda exclusive.

Full-length subframe connectors are available in bare steel or black powdercoated finishes. The black powdercoat version can be scraped, welded over and only the weld joints will need to be spray-painted rather than the entire kit needing to be spray-painted with bare connectors.

Note: 1996-98 Mustang Cobras will require modifications to the transmission crossmember mounting points. Will fit convertible models as well as hatch back and notch back coupe. Call our sales reps for details.

Fox full length subs
Great fit, installed these and then about a week later installed another companies full length, that also weld in at the torque boxes. With the Steedas the torque box plate fit significantly tighter where they slide into lower control arm area. The torque box plates are also predrilled for plug welds while the others weren't. This is kinda two sided especially if your torque boxes have seen a lot of Jack's. I ended up using a slide hammer to pull the box down to combat the gap. The bends that follow the contour of the chassis were tighter with these. Final thing I noticed is the seat brackets are coated with anticorrosion (cadium?) Where the others were bare. I got 10% off when I bought these and while they were slightly more expensive 20ish bucks they are well worth it.
