Roush 05-2010 Mustang GT 8 Bolt Aluminum Flywheel - 404000

This Mustang Flywheel is a high performance ROUSH® product that can increase the acceleration of the 2005-2010 Mustangs.

This is accomplished with the flywheel's light weight, which has less rotational inertia than the stock flywheel, and this is the same flywheel as those used for the ROUSH P-51™ program.

The default factory crank shaft has a 6-bolt interface to the flywheel. The upgraded ROUSH engine package for the 4.6L engine has a crankshaft with a 8-bolt interface
