Product Details

LuK LFW103 is a clutch flywheel designed for manual transmission service where a stable clutch contact surface is critical. The flywheel is manufactured to OE specifications so it matches the original design requirements for the vehicle application. That makes it a direct replacement choice for clutch jobs on Chevrolet and GMC trucks, vans, and SUVs from the mid-1980s through the late 1990s. This part cross-references Sachs NFW1007 for the same application.
