Pretty confrontational for your first post. No I just don't know WTF I'm talking about when daring to suggest the OE Luk clutch isn't up to hard use, lower gears, larger tires, etc. Actually I do, and the OE Luk clutch is VERY well known for standing up to such uses. I'm one who pushed his Luk clutch to the point it smoked on most of the rock crawling trails my TJ was on with fair frequency. On the TJ in the below photo, which was my previous (stolen) TJ, it was running 4.88 gears and 35" tires. It was a rock crawler. As in the below pic, I was regularly smoking the clutch due to the extreme terrain and even when I replaced the clutch at 162k miles as a precaution before doing Sledgehammer in Johnson Valley, it still had a lot of life on it. So much so I regretted changing it so soon. The Jeep was running Superior Evolution 4340 shafts in the rear and lots of upgrades but the Luk clutch? Nope, it handles such wheeling without problem.
Regularly being smoked on trails like this and not failing is a pretty good testament to the ability of the Luk to hold up. In fact the OE Luk with 162k miles got replaced with another Luk... at 1/3 the cost of a Centerforce. And actually, in 23 years of TJ ownership and active participation in the major Jeep forums, I do believe you're the first to push a Centerforce clutch. Centerforce clutches are great for some applications but IMHO and many others, their added cost just isn't warranted given the $80 Luk's widespread reputation for holding up just fine. In even very difficult wheeling uses.
