Spec 12-15 Hyundai Genesis Coupe 3.8L Stage 1 Clutch Kit
If your 2012-2015 Hyundai Genesis Coupe 3.8L six-speed is slipping in third and fourth at full throttle, chattering when you pull away, or the pedal now engages near the top of its travel, the factory clutch is usually done. The SPEC SY831-2 is a Stage 1 clutch kit built for the later 3.8L V6 cars, and it is the mildest step in SPEC's lineup for this engine: a street clutch that restores full grip without turning the car into a chore in traffic.
The clutch sits between the V6 flywheel and the six-speed manual gearbox. The pressure plate clamps the friction disc against the flywheel so engine torque passes into the input shaft; pressing the pedal moves the hydraulic release bearing and lifts the clamp. SPEC rates the SY831-2 at 430 ft-lb of torque capacity, which is well above what a stock or bolt-on 3.8L makes at the crank, so the extra margin goes into holding firmly when the clutch is worn by launches or heat rather than into a heavier pedal. If you are planning forced induction, SPEC lists stronger kits for the same car, from the Stage 2 SY832-2 (485 ft-lb) up to the Stage 5 SY835-2 (820 ft-lb).
A manual clutch does not set a slip trouble code on this car, so diagnosis is done by feel and inspection, not a scan tool.
In fourth gear at about 2,500 rpm, go to full throttle. If the tachometer climbs faster than road speed, the disc is slipping. Before you buy, rule out a soft or air-filled hydraulic system and check for oil on the bellhousing from a rear main seal, because oil will contaminate any new disc. Our transmission slipping diagnosis guide walks through telling true slip from other drivetrain faults, and shift flare vs slip explains what you are actually feeling.
This listing covers the Hyundai Genesis Coupe 3.8L V6 with the manual transmission, model years 2012-2015. SPEC lists SY831-2 for the 3.8L built from January 2012 and for 2013-2016 cars, so check the build date on the door sticker if yours is an early 2012. Important: SPEC's 2013-2016 application note states these clutch kits fit SPEC's flywheel only, and SPEC's matching steel flywheel is SY83S-4. Plan on running the SPEC flywheel with this kit rather than the factory one. The earlier 2009-2010 3.8L uses a different kit, the SPEC SY381-2, so do not mix the two. If you are not sure which version you have, send us your year and VIN before ordering.

SPEC lists SY831-2 for the 3.8L built from January 2012 and for 2013-2016 cars. Check the build date on your door sticker; 2009-2010 3.8L cars use the SY381-2 instead. Send us your VIN if you are unsure.
Yes. SPEC's application note for the 2013-2016 Genesis Coupe 3.8L states these clutch kits fit SPEC's flywheel only. SPEC's steel flywheel for this car is SY83S-4.
SPEC rates SY831-2 at 430 ft-lb of torque capacity. That is plenty for a stock or bolt-on 3.8L. For a supercharged or turbo build, step up to SPEC's Stage 2 or higher kits.
The clutch shares the brake fluid reservoir, so bleed it with fresh DOT 3 or DOT 4 brake fluid from a sealed bottle after the install.
Stage 1 is the entry step in SPEC's ladder for this car and is intended as a street clutch. If pedal feel matters most to you, stay at Stage 1 rather than jumping to the higher-torque stages.
Drive normally for the first few hundred miles: no launches, no full-throttle shifts and no long slipping on hills. That lets the disc bed in evenly against the flywheel.
