XClutch 10-15 Chevrolet Camaro 6.2L 9in Twin Solid Ceramic Clutch Kit

Put a cam, a supercharger or a turbo kit on a fifth-generation Camaro SS and the factory clutch is usually the first thing to give up. The XClutch XKGM23639-2E is a Stage 5 9 inch twin disc kit for the 2010 to 2015 Camaro with the 6.2L LS3 and six-speed manual. It pairs two rigid ceramic discs with a chromoly flywheel and a new hydraulic release bearing, and XClutch builds it for high horsepower motorsport use where heat and torque capacity matter most.

What this twin disc kit does in an LS3 Camaro

In the manual SS, the LS3 makes 426 hp and 420 lb-ft from the factory and feeds a Tremec TR-6060 six-speed. Add power and the single factory disc runs out of clamp and surface area. This kit splits the job across two 9 inch discs separated by a floating intermediate plate, so friction area roughly doubles in a compact 9 inch package, and the chromoly flywheel and alloy hat keep the rotating assembly light.

This is the rigid, or solid hub, version. With no spring pack in the hubs, every bit of engagement goes straight to the driveline. That gives the most direct, consistent hookup on a drag launch or road course, and it is the reason XClutch rates the ceramic twin for high heat and torque capacity. The tradeoff is more noise and chatter on the street and more shock to the gearbox and rear end. If the car is mostly a street car, look at the ACT Mod-Twin 10.5 inch sprung street kit or the Exedy Stage 1 organic kit instead. XClutch also makes twin solid organic and 10.5 inch twin sprung organic versions for this car.

Symptoms that mean you have outgrown your clutch

• Slip in third or fourth at wide-open throttle after adding boost or a cam
• The engagement point rising as the disc wears thin
• Clutch fade after back-to-back passes or a hot track session
• A burnt smell and a glazed disc that was replaced recently
• Your power level is above what your current clutch is rated to hold

How to confirm before you buy

Do a slip test: fourth gear at about 2,500 rpm, then full throttle. Revs that climb faster than road speed point to the clutch. Fifth-gen Camaros use a concentric slave cylinder inside the bellhousing, and a leaking slave can soak the disc in fluid or keep the clutch partly applied, so check for fluid at the bellhousing and a soft or sinking pedal before you condemn the discs. For planning the bill, see our manual versus automatic repair cost guide.

Fitment

This listing covers the 2010 to 2015 Chevrolet Camaro with the 6.2L V8 and six-speed manual, and XClutch lists the application as the LS3 SS. Automatic SS cars use the L99 and do not apply. The 2012 to 2015 ZL1 also has a 6.2L, but it is supercharged with its own clutch, so ZL1 and 1LE owners should send us the year and last 7 of the VIN before ordering. More parts are in our rebuild kits department.

Install notes

• Clean the crank flange and the new flywheel, use thread locker on the flywheel bolts, and torque them to GM specification. An LS crank holding tool keeps the crank still while you torque.
• Find the Transmission Side markings on both discs, then stack disc, intermediate plate and disc. XClutch wants at least 0.5mm of clearance between the hubs to prove the orientation is right.
• Center the discs with an alignment tool and draw the 20 M6 pressure plate bolts down a turn at a time in a circle to 18 Nm (13 ft-lb).
• Do not press the new release bearing in by hand or spray it with brake cleaner. Mount it square and bleed slowly with fresh fluid of the spec GM lists.
• A rattle from the floating intermediate plate with the pedal down is normal on a twin disc.

Does this fit the Camaro ZL1?

The listing is for the 6.2L manual Camaro and XClutch lists the LS3 SS. The ZL1 is a supercharged 6.2L with a different clutch, so send us the year and last 7 of the VIN before ordering.

Is the rigid ceramic version streetable?

It can be driven on the street, but the solid hubs and ceramic friction make it more abrupt and noisier than an organic or sprung kit. It is best for drag and track cars with serious power.

Do I need a new slave cylinder?

No. The kit includes a hydraulic release bearing. Do not depress it by hand before fitting and keep solvents away from its seals.

Is a flywheel included?

Yes. The kit comes with a chromoly flywheel matched to the twin disc assembly.

Why does the clutch rattle with the pedal pressed?

The intermediate plate floats between the two discs. XClutch notes this rattle is normal for multi-plate clutches and does not affect operation.
