A lightweight alternative to the 9" IRS iron center section, this aluminum center section helps keep your Mustang as light as possible for better track times. If you are looking for a stronger system that can help you launch reliably at the track but still keeps weight low, the GForce Engineering aluminum center section kit is the way to go. 

A race-ready solution to help you take your Mustang's performance up a notch.  The GForce Engineering 9-inch IRS Aluminum Center Section Kit comes with everything you need to overhaul your drive-line from the transmission back. The kit comes with a fabricated housing, heavy-duty front mount, solid aluminum bushings, 35-spline inner stubs, one-piece machined outer stubs, your choice of renegade or outlaw axle shafts, necessary hardware, Strange Pro HD aluminum third member, and a 4" aluminum one-piece driveshaft. 

Make sure you can put power to the ground every time you launch. This kit allows your Mustang to retain an IRS and reliably put power to the ground. The stock IRS can begin to show its weak points as you start increasing power on S550 Mustangs, so upgrading the IRS is a great way to ensure that your S550 will put power to the ground.

Great driveability and incredible strength with the Strange S-Trac differential. The helical gear differential provides smooth power transfer, quiet operation, and dependable operation. The differential offers impressive strength with 9310 steel internal gears that have been heat-treated and cold-treated for durability and reduced wear. The clutchless differential delivers maximum traction and acceleration.
