Product Description

The Clutch Masters FW-037-SF lightweight steel flywheel is a performance upgrade designed to replace the heavier stock flywheel on a range of Honda and Acura manual transmission vehicles.

Its CNC-machined and balanced design helps ensure smooth operation under spirited driving conditions.

Compatible with 2002-2006 Acura RSX and 2002-2011 Honda Civic Si models, as well as select TSX, Accord, and ILX manuals, the FW-037-SF is a solid choice for enthusiasts upgrading their clutch system or seeking more engaging performance from their driveline. The steel friction surface is resurfacing-capable, extending service life, and the SFI-certified construction meets motorsport safety standards for peace of mind on street or track use.
