So I am in the market for a clutch kit for my cj. I am going to be running a 360 4:56 gears and a t177 trans. I have looked at both center force and clutch masters. My question is are either of these a good choice for a trail and rock crawler rig? what are the advantages over something less costly
I would recommend Luk clutches. They are what the new car industry uses mostly. Since I started using them I have had a nice easy peddle and never a slipping problem. In fact I put some time in the Oregon coastal sand dunes and that is about the greatest load you can put on a clutch.
I also have one in my five yard dump truck 1964 f750 air brakes an old forest service rig with ten lug wheels hauling up to 26,000. I get it on some steep long grades in low gear the luk clutch does not slip. The one prior did and once removed it looked like new.
You want to have a real strong left leg if you go centerforce. It makes for a very heavy pedal that is no fun in traffic.

The Luk clutch kits in my opinion are a good choice if your not going to do a lot of full throttle assaults on asphalt doing burnouts or pulling people out of the mud where you are really lugging the motor in a high traction situation.
I have run CenterForce clutches in the past in a CJ5 with a 400hp 360 and I could not tell a difference in the clutch peddle feel.

I am using a LUK clutch also. I would not swear to it but if I hammer it hard on black top in 2nd ( 360 and T18) gear it sometimes feels like it slips a bit but it could be my imagination. Other than that I have not had a bit of trouble out of it.
Break the engine in the way you plan on driving it. Like ya stole it!

I did that racing, new engine off the bench after running a half hour or so in the machine off to the track. Time had a lot to do with that. Sunday was race day and I had to be on that track. I never brake in my engines like that any longer, I take the time and brake them in like I am honing something.
You can learn a lot from failure.
