Spec 2017 Ford Focus RS 2.3T Stage 2+ Clutch Kit
SPEC SFFRS3H is a Stage 2+ single-disc clutch kit for the Mk3 Ford Focus RS with the 2.3L EcoBoost, all-wheel drive and six-speed manual. Our listing is titled for the 2017 RS. It is aimed at the RS owner running a stage 1 or stage 2 tune who has started to feel the clutch slip in the upper gears, or whose original clutch is simply worn out, and who wants more holding power without giving up a smooth daily-driver engagement or buying a new flywheel.
Every bit of the RS engine's torque has to pass through the clutch before the transmission and rear drive unit split it between the axles, and an AWD car with sticky tires gives the clutch nowhere to hide: the tires do not spin, so the clutch slips instead. SPEC rates SFFRS3H at 425 ft-lb of torque capacity. The disc uses SPEC's Stage 2+ multi-friction lining, which SPEC describes as keeping the drivability of its Kevlar Stage 2 while adding 15 to 20 percent more torque capacity. In the car that means a progressive takeoff in traffic and a friction level that stays consistent after a few hard pulls. SPEC lists the kit's weight at 16 lb.
SPEC lists SFFRS3H for use with the original dual-mass flywheel or a single-mass billet flywheel made for the OE clutch fitment. That flexibility is the reason many owners choose it: if the factory dual-mass is healthy, it can stay, along with the quieter idle it gives.
Clutch slip does not set a trouble code by itself. Scan for boost, fueling or misfire codes first, because any of those can make the car feel weak.
Do a sixth-gear roll-on from around 2,500 rpm while logging rpm and speed; if rpm jumps and speed does not, the clutch is slipping. Check the clutch fluid level and look for a soft or sticking pedal, since hydraulic problems can mimic a worn clutch. On an RS, make sure any knock or drone you hear is not coming from the rear drive unit before blaming the clutch. Our slipping diagnosis guide covers how to isolate slip, and the manual repair cost guide helps you budget the job.
Our listing names the 2017 Focus RS 2.3T. SPEC's catalog lists SFFRS3H for the Focus RS Mk3 across 2016-2018, so it is the same kit for all three US model years. It is not for the Focus ST, which has a different clutch and its own SPEC kits, and it does not fit non-RS Focus models. If your car already has an aftermarket flywheel, confirm it is built for the OE clutch pattern. Send your year and VIN if you want us to double-check. More RS clutch parts are in the rebuild kits category.
If your RS is heading past 425 ft-lb or onto the track, compare the ACT FF5-HDSS kit, rated at 500 ft-lb with a single-mass flywheel, or the ACT FF5-XTSS kit with ACT's Extreme pressure plate for the same car.

Yes. Our listing is titled 2017, but SPEC lists SFFRS3H for the Focus RS Mk3 from 2016 through 2018. Send us your VIN if you want it confirmed.
Yes, if it is in good condition. SPEC lists this kit for use with the OE dual-mass flywheel or a single-mass billet flywheel made for the OE clutch fitment.
SPEC rates SFFRS3H at 425 ft-lb of torque capacity. For builds beyond that, look at a higher-rated kit such as the ACT FF5-HDSS at 500 ft-lb.
Yes. SPEC's Stage 2+ multi-friction disc is designed to keep the drivability of its Stage 2 disc while adding 15 to 20 percent more torque capacity, so engagement stays progressive.
No. The ST uses a different clutch. SPEC offers separate ST kits such as SF333F-3.
