Spec 09-10 Hyundai Genesis Coupe 3.8L Stage 3 Clutch Kit (Must Use Spec FW)
SPEC SY383-2 is the Stage 3 clutch kit for the early Hyundai Genesis Coupe 3.8L V6 with the six-speed manual. Our listing covers the 2009 and 2010 cars. It is built for owners whose 3.8 now makes enough power with intake, headers, tune or forced induction that the stock clutch slips, and who want a big jump in holding capacity instead of another stock-style disc. One rule comes with it: SPEC says this kit must run on a SPEC flywheel.
The Genesis Coupe is rear-wheel drive, so the clutch sits between the Lambda 3.8 V6 and the six-speed gearbox. The pressure plate clamps the disc to the flywheel, and the hydraulic release system pulls that clamp off when you press the pedal. SPEC describes its Stage 3 disc as a carbon semi-metallic 6-puck design for street and race cars, with aggressive but streetable engagement. SPEC rates SY383-2 at 605 ft-lb of torque capacity, against 443 ft-lb for its Stage 1 kit for the same cars, with a listed kit weight of 19 lb.
A puck disc has less friction area than a full-face disc and bites harder, so expect a shorter engagement window and some chatter if you slip it gently in a parking lot. That is the trade for holding real power. If the car is a mostly stock daily driver, the SPEC Stage 1 SY381-2 is the smoother choice.
Do a roll-on in fourth gear from about 2,500 rpm at full throttle and watch the tach against road speed; if rpm climbs ahead of the car, the disc is slipping. Our slipping diagnosis guide covers that test, and flare vs. slip helps describe what you feel. Before blaming the disc, check the clutch fluid, bleed the hydraulics if the pedal is soft, and look for oil at the bottom of the bellhousing from a rear main seal. Also decide on the flywheel now, because this kit is not designed to go on the factory dual-mass part.
Our listing is the 2009 to 2010 Genesis Coupe 3.8L V6 manual. SPEC's own application for SY383-2 is the 3.8L with the non-ratcheting clutch, built through 22 December 2011. Cars built from January 2012 on, and all 2013 and later 3.8 cars, use a different SPEC clutch, sold here as the 2012-2015 SPEC Stage 1 kit. Check the build month on the driver door jamb label. The 2.0T four-cylinder and automatic cars do not fit. If you are unsure, send us the VIN and build date before ordering. Other clutch kits are in our rebuild kits collection.
This SPEC Stage 3 kit is new, in stock, ships the same business day from the USA and carries a 1-year warranty.

No. SPEC lists this kit as requiring a SPEC flywheel. The SPEC SY38S steel flywheel is listed for the same 2009 to December 2011 cars.
Only cars built through 22 December 2011 with the non-ratcheting clutch. Later 2012 builds and 2013-up 3.8 cars use the SY831-2 family. Check the door jamb build date or send us the VIN.
SPEC rates SY383-2 at 605 ft-lb, compared with 443 ft-lb for its SY381-2 Stage 1 kit for the same cars.
SPEC calls the Stage 3 6-puck engagement aggressive but streetable. It works on the street, but engagement is quicker and it can chatter when slipped gently. A mostly stock car will be happier with Stage 1.
No. The 2.0T uses a different clutch and flywheel. This kit is only for the 3.8L V6 manual.
