Aftermarket clutch for 12-14 3.6L JK??

For those of us who have been having problems with the factory clutch. I just found out the Centerforce Clutch just came up with an aftermarket kit to replace the factory flywheel and clutch. The Centerforce kit includes a high inertia flywheel that helps maintain engine RPM in rough terrain. The Centerforce flywheel is a Billet Steel Flywheel that replaces the O.E. 33 lb. flywheel with a higher quality 50 lb. Billet Steel Flywheel. Centerforce has two different kits a Dual Friction part# (KDF379176) also a Centerforce II part# (KCFT379176). Both kits include High Inertia Flywheel, Pressure Plate, Disc, Alignment Tool, Pilot Bearing, Throw Out Bearing and Bolts. Both kits are direct bolt on replacement with a higher holding capacity for those big off road tires. I called Centerforce at 928-771-8422 to get this information. Both kits fit 2012-14 3.6L JK Wrangler

Thanks for that info, I do not have problems with mine but when it does need replacing I will probably go this route.
BTW, your post read like a commercial, don't know if it is but with this being your first post it probably raises an eyebrow.
Welcome.

LOL just read on another forum of which you just joined and posted the exact same thread as your first post. One difference is on that forum you state your residence is Prescott Valley, AZ. coincidentally the same place Centerforce is based.
SPAM.

Busted - it might be good info, but since you tried to do it covertly/ disingenuously it's SPAM in my book.

I would also doubt adding weight is good on a flywheel, things usually perform and drive better with less weight on the flywheel, just my 2 cents

Can't find any pricing info. The OEM clutch is a ripoff at almost $500. Although, I'm concerned about the driving characteristics with a heavier flywheel with the aftermarket clutch. The rev hang is significant with the stock flywheel.

In my jeep i'm running 37's with 4.88 gears. With the stock clutch it would want to stall at times, with this heavier set up I can let the clutch out without pushing the gas and the jeep will not stall. I'm not sure but I think that a lighter flywheel is for something like road racing where you need the RPM's out of the corners.

I'm glad to see some aftermarket options coming out for the newer JKs. Choosing flywheel weight has more to do with weight of the vehicle, gearing, driving style, and engine power than just light vs. heavy. Lighter yields faster revs and retains less energy than a heavier flywheel. Heavier would retain more energy and the engine would lose less RPMs between shifts. I would think a heavier flywheel would benefit us offroad chugging along. More inertia would make it harder to bog the engine down. Just a couple of things to consider.

You didn't answer the first question. Is this SPAM? Be honest. Come on, you can do it. Regardless, this is good news but the delivery is off if you work for Centerforce.

not bad at all, the shifts are much smoother, pretty much butter smooth, the jeep feels more responsive. The 'marbles in a can' noise is still there, but not as loud as before, actually it is not loud at all. So far i like it.

Glad to hear it, ive been looking at a clutch kit myself, its just not in the cards right now they are pricey. Good to hear some positive feedback tho.

My factory clutch was making some noisy when in neutral (don't know how to describe it, kind of like marbles in a can noise), when i pushed the clutch in the noise would go away. I changed the throw out bearings once and it helped for about 200 miles lol. After 200 miles the noise came back. The new clutch is way more quiet than the OEM.

Good to hear. I'll definitely do the swap this winter while I'm upgrading the t-case and it's halfway apart already.

its in the clutch, when I pressed the clutch in neutral the noise would go away. And now, it is much quieter with the new clutch.

does the flywheel make a difference in drivability or feel?

I think so. The jeep feels more responsive, the initial start in the first gear feels much better, the shifts are smoother. I think a heavier flywheel contributes to all of that.

I don't care if this is spam/crossposting or whatever, if this kit really is available this is very good news. Centerforce makes great stuff and the Wranlger has always yearned for a quality aftermarket clutch kit.

I just installed the Centerforce II in my 2012 JKU this past weekend. I can say there is definitely a difference when pulling out with the heavy flywheel and I love it. Also have a 2015 so I can get a good comparison. I barely need to give it gas in the 2012 with the Centerforce II, so that is what I would recommend for those who need to replace their clutch.

Was really hoping this might completely rid the loud throw out bearing noise. Glad to hear it's an improvement.

I have been reading the posts trying to determine the best clutch replacement for my 2012 JK Wrangler. I too am having these sounds when in neutral. It does go away when the clutch is in and it will also go away when I move the manual shift a little up or down from neutral position. I felt like maybe something was not right. I burned my clutch over 2 years ago trying to climb a rock mound in four wheel high gear. Not a smart thing to do. Burned the clutch in first gear and ever since my standing still accelerations are not so great. I was hoping to solve most of those issues with a new clutch. Thanks for the info.
