Nodular iron flywheels offer high-quality, yet low-cost alternatives to the hassles of resurfacing a flywheel. Nodular iron flywheels are stronger than the OEM models, and these Silver Sport Transmissions (SST) by McLeod units are direct bolt-in units. Don't overlook your flywheel when replacing your clutch, but don't resurface, replace with SST by McLeod nodular iron flywheels.
