GForce Engineering designed the IRS center section kit to help provide the strength that drag racers need in their Mustangs. This kit completely replaces your factory driveline from the transmission back for a much stronger system that can put the power to the ground every time. 

Fully-fabricated IRS for increased strength. The 9 inch IRS is a bolt-in kit that takes your Mustang up a notch. This kit adds rigidity, reduces noise, and improves strength over the OE IRS. The housing is laser cut, CNC formed, and finally TIG-welded for a stunning finish and incredible strength. 

Race-ready kit for your S550 Mustang. The GForce Engineering kit includes the housing, the third member (pumpkin), axles, stub shafts, and a driveshaft. The half-shaft axles can support more power and feature anti-wheel hop technology for better performance at the track. Solid aluminum bushings are included to keep your Mustang planted.

Strange helical differential that can handle impressive power. The S-Trac helical gear differential is built to put power to the ground. The mechanical and clutchless design provides the best traction and acceleration possible. Thrust surfaces are coated in a dry film solid lubricant coating that reduces wear. Smooth power transfer and quiet operation is also achieved thanks to the S-Trac's design.

Product Benefits: 
  • Replaces your driveline from the transmission back
