Clutch Masters 17-21 Honda Civic 1.5L Turbo Steel Flywheel
The Clutch Masters FW-150-SF is a single-mass steel flywheel for the 10th-generation Honda Civic with the 1.5 L turbo and six-speed manual. Most buyers are replacing a worn factory dual-mass flywheel, the kind that rattles at idle, clunks on and off throttle or shudders on takeoff, or they are installing a sprung aftermarket clutch that needs a single-mass flywheel to work.
From the factory, the manual 1.5 L turbo Civic uses a dual-mass flywheel: two plates joined by springs that soak up engine pulses for a quiet, smooth drive. Clutch Masters puts the stock unit at about 31 lb. The springs and bearings inside wear, and a tired dual-mass flywheel is a common reason these cars come in for clutch work. The FW-150-SF replaces it with one solid piece. Clutch Masters lists it at 26 lb, so it is lighter than stock but keeps more rotating mass than the company's aluminum version. That makes it the commuter choice: the engine still revs more freely, but stop-and-go traffic and hill starts stay manageable. It is CNC machined from a 1045 steel billet core, zero balanced, black oxide coated and SFI 1.2 certified.
Idle rattle that goes quiet with the pedal pressed points at the dual-mass flywheel; our dual-mass flywheel failure guide explains the checks, including rocking the inner plate with the transmission out. If the tach rises faster than road speed on a pull, the disc is slipping; use the slipping diagnosis guide and the clutch slipping guide. Read dual-mass vs. single-mass first so you know a single-mass setup adds some gear rattle and vibration compared to stock.
This flywheel fits the 2017-2021 Honda Civic 1.5 L turbo with the six-speed manual. Clutch Masters names the EX and Si applications; the manual hatchbacks with the same engine use the same flywheel. It does not fit CVT cars, which use a flexplate and torque converter, or the 2.0 L non-turbo manual Civic. The 2022-up 11th-generation 1.5 L turbo uses a different flywheel, the FW-222-SF. If you are not sure which you have, send us your year, trim and VIN and we will confirm before it ships. More Civic parts are in our clutch and rebuild kits section.

Clutch Masters lists the FW-150-SF at 26 lb and the factory dual-mass flywheel at about 31 lb. Its aluminum version is about 17.5 lb if you want quicker revs.
A clutch with a sprung disc. Clutch Masters builds its sprung 1.5T kits, such as the FX100 08150-HD00-D, for a single-mass flywheel. Its rigid-disc kits are meant for the factory dual-mass flywheel.
No. The 2022-up 1.5 L turbo uses a different flywheel. This part is for 2017-2021 manual cars.
No. CVT cars have a flexplate and torque converter instead of a flywheel and clutch.
A little. Without the dual-mass springs you can hear more gear rattle at idle and feel more vibration at low rpm. The steel version keeps more mass than aluminum to soften that.
