South Bend Clutch Stage 3 Daily Driver Clutch Kits

South Bend Clutch Stage 3 Daily Driver clutch kits are recommended for single mass flywheel (SMF), when original design is dual mass flywheel (DMF). These clutch packages are designed for high-horsepower vehicles desiring a start performance similar to OE. The pressure plate is race engineered (SS) and SFI-approved with significant load increase over stage 1 and 2 pressure plates (+600-800 lbs.). Expect a pedal effort increase of 20 to 25 percent. Discs are assembled with heat-treated wear-resistant hubs, as well as drive plates and springs for high-load transfer and dependable operation. The sprung centers on the disc, in conjunction with the marcel fin between the linings, create a dual dampening effect that simulates OE start performance. A performance organic friction material with a high metal content increases torque and rpm capability—and maintains low operating temperatures, which reduce wear and glazing. South Bend Clutch Stage 3 Daily Driver clutch kits are the perfect match for your high performance street machine and occasional track use. Order the kit recommended for your application.

LuK Clutch DMF Flywheels

The downsizing of modern passenger car engines enables reduced fuel consumption and CO2 emissions, but can also increase rotational irregularities and natural vibrations. Torsional vibrations transmitted to other components in the drivetrain diminishes comfort and may even lead to component damage, therefore effective vibration damping is essential. LuK dual mass flywheels (DMF) reliably dampen torsional vibrations in the powertrain and ensure high gearshift and driving comfort in all speed ranges. Unlike a conventional flywheel, DMFs consists of two masses which are mounted to rotate against each other. A damping system in the form of arc springs is integrated to almost completely absorb the torsional vibrations of the engine. Precisely matched to the respective vehicle, each LuK DMF enables low-speed driving and ensures lower fuel consumption, as well as reduced emissions. Order the proper size for your vehicle.
