Steel Flywheel, 8-Bolt, 164-Tooth

The SR Performance Steel Flywheel is engineered as a direct replacement for your Mustang's stock flywheel, offering superior performance and durability compared to resurfacing an old unit. Constructed from robust steel, this flywheel provides the necessary strength for demanding street and race applications, particularly where off-the-line acceleration is a priority. It features an 8-bolt crank pattern, a 164-tooth ring gear, and a 0 oz balance. Safety and compliance are paramount, as this flywheel is SFI certified. This certification is crucial for participants in high-performance driving events, track days, or drag racing, ensuring you can compete with peace of mind. Beyond racing, SFI certification offers an added layer of safety for daily drivers, mitigating the risk of catastrophic failure that can occur with stock cast flywheels at higher RPMs. Fitment for this 8-bolt flywheel is extensive across several Mustang generations. It is compatible with 1999-Mid 2001 GT models, 1996-2004 Cobra models, 2003-2004 Mach 1 models, and 2011-2017 GT and V6 models. A critical technical note specifies that the 8-bolt main is found in 1999-mid 2001 Mustang GTs with a production date ending on 06/01. It is important to verify your engine's crankshaft bolt pattern, as Windsor-built engines generally use an 8-bolt crank while Romeo-built engines use a 6-bolt crank. Exceptions, such as the 2001 Bullitt Edition Mustang with a Romeo engine, require careful verification. If unsure, consulting with a Ford dealer is recommended to confirm whether your vehicle has a 6 or 8-bolt main. Installation of this flywheel requires mechanical expertise or professional installation, with an approximate time of 4 hours. The product includes one flywheel.
