ACT 16-17 Ford Focus RS HD/Perf Street Sprung Clutch Kit
A tuned Focus RS makes the factory clutch work hard, and owners with a stage 1 or stage 2 flash often feel it first as slip in the upper gears or a dual-mass flywheel that has started to rattle and shudder. ACT FF5-HDSS replaces the whole stack on the 2016-2017 Focus RS with a Heavy Duty pressure plate, a sprung Performance Street disc and a single-mass XACT Streetlite flywheel. ACT rates it at 500 ft-lb at the crank, 35 percent more than the original clutch, while keeping light to moderate pedal feel for daily use.
The F024 Heavy Duty pressure plate uses ACT's heat-treated diaphragm to add clamp load and limit deflection, so it keeps squeezing the disc when the 2.3 EcoBoost is making boost in fifth and sixth. The 3001012 disc is 240 mm (9.4 in) with a 1 inch input spline and an organic, high-copper lining on a steel backing. Its sprung center takes the edge off engagement and protects the six-speed and the AWD driveline from torque spikes.
The biggest change is the flywheel. FF5-HDSS must use the included 601020 XACT Streetlite, a single-mass flywheel in place of the factory dual-mass unit. ACT states plainly that gear rattle is expected with it, mostly at idle in neutral; that is the trade for faster revs and a flywheel that will not fail like a worn dual-mass. The kit also includes the RB009 release bearing, the AT130 alignment tool and pressure plate bolts (M8-1.25 x 20 mm), and weighs 29.6 lb.
A sixth gear roll-on from around 2,500 rpm shows slip quickly: rpm jumps but speed does not. Clutch hydraulic problems, a pedal that does not return fully, or an oil leak onto the friction surfaces can all copy clutch failure, so check fluid level, the slave cylinder and the rear main seal area first. On an AWD car, also make sure the noise you hear is not coming from the rear drive unit. Our slipping diagnosis guide covers how to isolate clutch slip, and the manual versus automatic repair cost guide helps you plan the labor.
This listing covers the 2016-2017 Ford Focus RS with the 2.3 liter EcoBoost and six-speed manual. ACT's own chart is broader: the same FF5-HDSS kit is listed for 2016-2018 Focus RS and for the 2013-2018 Focus ST 2.0 liter EcoBoost. If you own an ST or a 2018 RS, it is still the right part per ACT, but send your year and VIN if you want us to confirm before shipping. More options are in our rebuild kits department.
Plan on 15 to 40 percent more pedal effort, typical for ACT Heavy Duty plates. If you need more capacity later, the ACT FF5-XTSS Xtreme version uses a stiffer plate, and the F024 pressure plate is available on its own.

Yes. The kit must be used with the included ACT 601020 XACT Streetlite, a single-mass flywheel that takes the place of the factory dual-mass unit.
ACT says gear rattle is expected with its single-mass flywheel. It is a normal sound from the gearbox at idle, not a defect.
ACT rates FF5-HDSS at 500 ft-lb at the crank, 35 percent over the factory clutch.
Yes. ACT includes M8-1.25 x 20 mm pressure plate bolts, plus the RB009 release bearing and AT130 alignment tool.
300 to 500 miles of mild stop-and-go driving on the organic disc before hard launches, without overheating the clutch.
