Clutch Masters 14-18 Mazda3 2.5L Single Disc FX250 Sprung Clutch Kit
Clutch Masters 10775-HD0F-D is the FX250 street-performance clutch for the 2014-2018 Mazda3 with the 2.5L Skyactiv-G four and the six-speed manual. Most people searching for it have a 2.5L Mazda3 whose clutch now slips when they roll into the throttle in fifth or sixth, a pedal that grabs near the top of its travel, or a car that has picked up an intake, exhaust and tune and wants more holding power than the factory disc was built for. Read one point before anything else: this is the D version, a dampened disc that Clutch Masters designs to run against an aftermarket single-mass flywheel.
In the front-drive Mazda3 the clutch sits between the 2.5L and the six-speed transaxle and is worked by a hydraulic release system. The pressure plate clamps the disc to the flywheel; when you press the pedal the release bearing pushes the diaphragm fingers and frees the disc so you can change gear. The FX250 raises clamp load with a Power Plus I heavy-duty pressure plate and uses a hybrid disc: Fiber Tough facing on the pressure plate side for heat resistance, steel-backed organic facing on the flywheel side so takeoff stays smooth. A Marcel spring wafer under the friction cushions engagement, and the dampened hub takes up driveline shock that a solid flywheel does not absorb. Clutch Masters rates the system at 110 percent more holding capacity than stock. The box includes the disc, pressure plate, release bearing, an alignment tool and an instruction card; shipping weight is about 17 lb.
Warm the car up and run a simple load test: fourth gear at roughly 2,000 rpm, then full throttle. If rpm climbs faster than road speed, the disc is slipping. Our slipping diagnosis guide covers the test step by step, and the flare versus slip explainer helps separate a worn clutch from a driver-timing issue. Before pulling the transaxle, check the clutch fluid level and look for wetness at the slave and line. A release problem caused by air or a leak can feel like a bad clutch and costs far less to fix; see how to bleed a hydraulic clutch.
Our listing covers the 2014-2018 Mazda3 2.5L with the six-speed manual. Clutch Masters also lists this same part number for the 2014-2018 Mazda6 2.5L six-speed. It does not fit the 2.0L Mazda3, any automatic car, or the earlier 2004-2013 Mazda3 and Mazdaspeed3. Because the D disc is built for a single-mass flywheel, plan the flywheel at the same time; Clutch Masters makes the FW-775-AL aluminum flywheel for this car. If you are unsure which engine or transmission your car has, send us the year and VIN and we will check it. More parts are in our rebuild kits section.
If you expect to add more power later, compare the FX350 version for the same car, which trades a little smoothness for more grip.
