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.
Note: 1996-98 Mustang Cobras will require modifications to the transmission cross member mounting points. Will fit convertible models as well as hatchback and notchback coupes. Call our sales reps for details.
