Mustang Sub Frame Connectors


SPINTECH Performance Mufflers has developed a weld-in, full length frame connector. The INNOVATIVE step design is much stronger than anything else in its class and gives you more ground clearance.

 Weld-in connectors have proven to be more rigid and will not work loose like bold-in connectors do.

 SPINTECH's STEP-Connectors can easily be installed with just a welder. No cutting or drilling is required.

 SPINTECH also incorporates Torsional plates up front, as well as a heavy duty cross brace which bolts up to the factory seat bolts. This virtually eliminates any chassis flex.


SPINTECH's heavy duty full length SUB FRAME CONNECTOR will allow you to run SPINTECH's side exit exhaust without losing that valuable ground clearance.

Made of 1” x 2” x 1/8” structural tubing and 12ga. steel for the seat support brace and torsional pivot support plates.

Designed as a weld-in unit, they are contoured to fit the vehicles floor pan from front to rear clips. Therefore, additional strength and more ground clearance are attained.

Support plates are provided to be welded in place next to lower control arms to be used as pick up points for most lifts.
