ACT 2012 Honda Civic XT/Perf Street Sprung Clutch Kit
The ACT AR2-XTSS is a street clutch for K24-powered Hondas that have outgrown the factory clutch: the 2012 to 2015 Civic Si, the 2009 to 2014 Acura TSX, the 2013 to 2015 ILX 2.4 and the 2003 to 2012 Accord with the 2.4L four. It is the kit to look at when a tuned or turbocharged K24 starts to flare the revs in the upper gears, or when the original clutch is simply worn out and you want more holding power without moving to a puck disc.
AR2-XTSS pairs ACT's Xtreme pressure plate with a full-face organic sprung disc and a lighter XACT Streetlite flywheel. ACT rates it at 340 ft-lb at the crank, 64 percent over the original clutch. The Xtreme diaphragm raises clamp load and cuts deflection, while the high-copper organic lining with steel backing keeps engagement smooth enough for daily driving. The disc is 214 mm (8.4 in) on a 1.03125 in input shaft.
ACT notes that this kit must use the ACT flywheel, and it is included, so the factory flywheel comes off for good. Kit contents per ACT are the 600780 XACT Streetlite flywheel, the H024X Xtreme pressure plate, the 3000108 Performance Street sprung disc, the RB313 release bearing, the AT78 alignment tool and the PBNA004 pilot bushing.
Make sure the clutch is actually slipping and not failing to release. A soft or sinking pedal, dark fluid in the clutch reservoir or a weeping slave cylinder are hydraulic problems a new clutch will not cure. Look for oil at the bellhousing seam, because a crank or input seal leak will contaminate any new disc. Then do a roll-on in a high gear from low rpm; if the tach climbs ahead of road speed, the clutch is slipping. Our slipping diagnosis guide walks through it.
Our listing title says 2012 Honda Civic, which means the 2012 Civic Si and Si HFP with the K24Z7 and six-speed. ACT's application chart for AR2-XTSS is wider: 2012 to 2015 Civic Si, 2009 to 2014 Acura TSX 2.4 (K24Z3, six-speed), 2013 to 2015 Acura ILX 2.4 (K24Z7, six-speed) and 2003 to 2012 Accord 2.4 manual. It does not fit the 1.8L or 2.0L Civic, the V6 Accord or TSX, or the 2016-up Civic. If your car has had an engine or gearbox swap, send us the year and VIN and we will confirm before it ships. Shipping weight is about 25.3 lb. Browse other clutch parts in our rebuild kits category.
Want a lighter pedal? The AR2-HDSS Heavy Duty street kit uses the same idea with a softer plate. For drag or track builds, the AR2-XTR6 rigid 6-pad race kit steps up to a ceramic disc.

Yes. ACT lists AR2-XTSS for 2012 through 2015 Civic Si with the 2.4L K24Z7 six-speed. It does not fit the 2016 and later Civic.
ACT lists the 2009 to 2014 TSX 2.4, the 2013 to 2015 ILX 2.4 and the 2003 to 2012 Accord 2.4 manual. The V6 cars are not covered. Send your VIN if you want it checked.
No. ACT requires its own flywheel with this kit, and the 600780 XACT Streetlite flywheel is included in the box.
ACT rates AR2-XTSS at 340 ft-lb measured at the crank, 64 percent over the original clutch.
It uses a smooth-engaging organic disc, but the Xtreme plate raises pedal effort noticeably. If you mostly drive in traffic and make moderate power, the Heavy Duty AR2-HDSS is the softer option.
Honda clutch hydraulics run on brake fluid from the shared reservoir. Bleed with fresh fluid of the type in your owner's manual after the install.
