Spec13-15 Ford Fiesta 1.6L Stage 2+ Clutch Kit

The manual Ford Fiesta 1.6L is a light, fun car, but a high-mileage clutch shows itself quickly: the revs flare when you pull onto the highway, the car shudders as you let the pedal out on a hill, or a chirp appears every time you push the pedal down. Owners who have added an intake, exhaust or tune, or who autocross the car, often want something stronger than a stock disc. SPEC SF333H-5 is SPEC's Stage 2+ kit for the naturally aspirated 1.6L Fiesta with the manual gearbox.

What the Stage 2+ clutch kit does in a Fiesta 1.6L

On the manual Fiesta, a single friction disc sits between the flywheel and a diaphragm pressure plate. With the pedal released, the diaphragm clamps the disc and engine torque passes through it to the gearbox input shaft. Pressing the pedal pushes hydraulic fluid from the master cylinder at the pedal box to the release system, which lifts the diaphragm and frees the disc.

SPEC describes Stage 2+ as a multi-friction disc that keeps the drivability of its Stage 2 Kevlar disc while adding roughly 15 to 20 percent more torque capacity. In practice that means a pedal and engagement that still suit daily driving, with more margin against slip when the car is modified or driven hard. SPEC does not publish a torque figure for this particular kit, so we do not quote one. SPEC lists the kit weight at 11 lb.

Symptoms of a worn Fiesta clutch

• Engine speed climbs in fourth or fifth without the car accelerating
• Shudder or judder when moving off, especially uphill or in reverse
• Engagement point high near the top of the pedal travel
• A noise that appears or changes as the pedal goes down, pointing to the release bearing
• Grinding into first or reverse when the clutch is not releasing fully
• Burning smell after a steep driveway, stop-and-go traffic or track day

How to confirm before you buy

Do a slip check: warm engine, fourth gear at low rpm, then full throttle. If the tachometer climbs faster than the speedometer, the disc is slipping. Next, rule out hydraulics. A pedal that feels spongy, sinks, or sticks to the floor is a master or slave cylinder fault, and the Fiesta clutch master cylinder CV2Z-7A543-A is a common fix for that complaint. Our slipping diagnosis guide covers the test drive in more detail.

Fitment

Our listing title says 2013-2015. SPEC catalogs SF333H-5 for the Ford Fiesta 1.6L from 2011 to 2019 with a manual transmission. Two points matter here:

• This is not the Fiesta ST kit. SPEC lists the turbocharged Fiesta ST separately under the -9 suffix (SF333H-9), with different flywheel options. If your car is an ST, this kit is the wrong part.
• Automatic Fiestas use the PowerShift dual-clutch transmission, which is a completely different system. If your car is an automatic with shudder or harsh shifts, read our PowerShift DPS6 problems guide instead.

Check that the part number on the box reads SF333H-5, and if you are not sure what engine or gearbox your car has, send us the year and VIN before ordering.

Install notes

• A flywheel is not included. Inspect the original for heat cracks, blue spots and wear, and have it surfaced or replaced. SPEC lists a steel flywheel, SF33S-5, for this car.
• Center the disc on the flywheel with an alignment tool; our universal alignment tool kit is handy if one is not in the box.
• Tighten the pressure plate bolts a little at a time in a crisscross pattern so the cover pulls down evenly, then torque to the Ford specification.
• Clean the input shaft splines and apply only a thin film of high-temperature grease.
• Bleed the clutch hydraulics with the brake fluid type shown on the reservoir cap, then check that the pedal returns fully.
• Drive gently for the first few hundred miles so the friction surfaces seat before hard launches or autocross.

If you just want factory feel at a lower price, the Exedy OE Fiesta clutch kit is listed for the 2011 car.

Does SF333H-5 fit the Fiesta ST?

No. SPEC catalogs SF333H-5 for the 1.6L Fiesta without the turbo. The Fiesta ST uses SPEC's -9 series kits, such as SF333H-9.

Which years does it fit?

Our title lists 2013-2015, and SPEC catalogs the kit for the manual Fiesta 1.6L from 2011 through 2019. Send us your year and VIN if you want us to double check.

Will it fit an automatic Fiesta?

No. Automatic Fiestas use the PowerShift dual-clutch transmission, which uses a different clutch assembly and is not serviced with this kit.

Is a flywheel included?

No. Resurface or replace your flywheel. SPEC offers a steel flywheel, SF33S-5, for this application.

What is the difference between Stage 2 and Stage 2+?

SPEC says the Stage 2+ multi-friction disc keeps Stage 2 drivability while adding about 15 to 20 percent more torque capacity.

My pedal is soft. Will a new clutch fix it?

Usually not. A soft or sinking pedal points to the hydraulic master or slave cylinder. Check those before replacing the clutch.
