Clutch Masters 2-Piece Billet Aluminum Flywheels are made from the highest quality 6061-T6 or better grade aluminum. This material is chosen for its properties that are much more suitable for the environment than the one-piece chromoly units, with regards to heat dissipation and serviceability. The replaceable friction surface used is incredibly tough high carbon steel. This allows mating with any type of clutch friction material without worry. The starter ring gears are made of high carbon heat-treated steel for long lasting durability. The unit is buttoned together with military grade fasteners to make the premier flywheel in the industry. *Features* * Reduced mass equals increased acceleration. * A lightweight flywheel works particularly well with turbo-charged engines because it reduces typical turbo lag. * Increased supercharger efficiency due to less parasitic drag on the crank. * Improved mid-range torque in a normally aspirated engine due to not having to overcome the heavy weight of a stock flywheel. * CM uses only 6061-T6 aircraft grade or better billet aluminum in the manufacturer of its flywheels. * CM uses High Carbon steel for the friction surface. (Replaceable) * CM uses an OEM steel ring gear secured by bolts. * CM offers a limited lifetime warranty. * CM Billet Aluminum Flywheels meet SFI Spec 1.1 or 1.2 PartNumber : cmFW-H2B-AL Description : Lightweight Aluminum Flywheel Weight : 8lbs 1988-1991 Honda Civic Base L4.1493cc Drivetrain::Flywheels 1992-1995 Honda Civic CX L4.1493cc Drivetrain::Flywheels 1996-2000 Honda Civic CX L4.1590cc Drivetrain::Flywheels 1988-1995 Honda Civic DX L4.1493cc Drivetrain::Flywheels 1996-2000 Honda Civic DX L4.1590cc Drivetrain::Flywheels 1990-2000 Honda Civic EX L4.1590cc Drivetrain::Flywheels 1998-2000 Honda Civic GX L4.1590cc Drivetrain::Flywheels 1996-2000 Honda Civic HX L4.1590cc Drivetrain::Flywheels 1988-1995 Honda Civic LX L4.1493cc Drivetrain::Flywheels 1996-2000 Honda Civic LX L4.1590cc Drivetrain::Flywheels 1988-1991 Honda Civic RT 4WD L4.1590cc Drivetrain::Flywheels 1989-1995 Honda Civic Si L4.1590cc Drivetrain::Flywheels 1999-2000 Honda Civic Si L4.1595cc Drivetrain::Flywheels 1999 Honda Civic Value Package L4.1590cc Drivetrain::Flywheels 1992-1995 Honda Civic VX L4.1493cc Drivetrain::Flywheels 1988-1989 Honda Civic Wagovan L4.1493cc Drivetrain::Flywheels 1993-1995 Honda Civic del Sol S L4.1493cc Drivetrain::Flywheels 1996-1997 Honda Civic del Sol S L4.1590cc Drivetrain::Flywheels 1993-1997 Honda Civic del Sol Si L4.1590cc Drivetrain::Flywheels 1994-1995 Honda Civic del Sol VTEC L4.1590cc Drivetrain::Flywheels 1996-1997 Honda Civic del Sol VTEC L4.1595cc Drivetrain::Flywheels 1989-1991 Honda CRX Base L4.1493cc Drivetrain::Flywheels 1988 Honda CRX DX L4.1493cc Drivetrain::Flywheels 1988-1991 Honda CRX HF L4.1493cc Drivetrain::Flywheels 1988-1991 Honda CRX Si L4.1590cc Drivetrain::Flywheels
