I am getting ready to order a new clutch kit. I am
Just looking for some input on the differences and pros/cons of either a sbc triple ceramic or a sbc double feramic. Any suggestions Are appreciated!

What do you plan to do with it? I wouldn't suggest a triple unless you're sledpulling a lot. They can be driven daily but I don't suggest it. I love my triple and do drive it some but I don't let too many other people drive it.

It will be a daily driver and I will sledpull in my area and dragrace occasionally. I am kinda rough on the old girl, haha. She doesn't get any slack.

I daily drive a strapped dual disk, and I wouldn't have anything else. Quiet and smooth... Never having driven a triple, I can't say for sure, but don't think I would want to daily drive it.

What about the triple makes you not want to drive it everyday?

I also have a DD. And it's a big enough pain in the ass to drive in the city with stop and go traffic. From what I've heard of the tripple disc unless your truck is a dedicated puller/racer your better off with the DD. If your not going to be throwing more than 600 hp or 1100 ft/lb you should be fine with the dd

I think when my truck gets tuned next week, the guys say with nicks tune from duramaxtuner.com will put my truck over 1,000 ft lbs

My buddy has an 02 dmax zf with a sbc dd feramic. The clutch has the same pedal pressure as my stock clutch.

They aren't real driver friendly. You can't ease the clutch out per say. It enguages and disenguages within about 1-2" of peddle travel so it's either in or out. Mine is a sintered iron triple with a 4200lb weighted presure plate. You sure can't race with a triple disc. If you rush them you'll just grind gears :rolleyes:.

I hear "strapped dd" a lot. Whats the difference between a normal sb dd and a strapped dd?

I have a sb dd and if a triple is even rougher engagement, driving it as a daily driver especially if you do a lot of city driving would not be very enjoyable.

Yea I don't know for sure what a "strapped" dd is either?

well my mechanic showed me what makes it "strapped" ... but I aint real sure how to describe it. I'll try anyway- basically it's a "strap" of steel(?) bout 3" long, 1/2" wide?, maybe 3 of them(?) that holds something together... I forget exactly what tho. could be clutch disks to clutch "housing"? ..yea I'll just stop.

I may be able to get pictures tonight of my wore out south bend triple disk if someone wants to see it... I remember seeing the "straps" on it. just didn't pay that much attention.

Strapping refers to strapping the floater to the actual flywheel. Gets rid of the noise so it sounds like a single disk. On South Bend flywheels, each lug of the floater gets strapped, so three in total.

For daily driving my triple disc isn't terrible. It's not the choice for drag racing tho, I can back kyle up on that. Mine will grind too if I try and rush it

Do any of you guys know Caleb? He has the 05lly I think it's one of the fastest zfs in the country! He suggested a triple. He says you can shift much faster!

We all know Caleb :cool:. He must have a different triple than we do cause there is no way to rush a weighted one like mine. I could shift very very fast with my dual disc and my short throw shifter. I was always messing with fast cars but now there is no point :(.

Ok, well I was just following what Caleb said about that triple. He has one of the fastest trucks and he uses a triple. Why wouldn't he use a double if he could cut down even more time?

Just out of curiosity, as I will be making this purchase in the near future, does anyone know if getting a DD strapped costs any extra?

A dual disc probably won't hold the power Caleb is making. My guess is he had a non-weighted triple that's possibly ceramic.
Mine is a purpose build pulling clutch and not really ment to be driven daily.

I am looking at a triple ceramic or a double feramic.

Best bet is to call Peter or Brian at SBC and tell them what you are going to do with it.

Caleb only makes around 700 rwhp at his wheels from what he told me. He has a triple. Why would the southbend dd feramics be rated At 750 if they wouldn't hold up to it?

I did talk to Peter at southbend, and told him what i wanted to do with my truck. I told him that I will sledpull, dragrace, and daily drive it. He recommended me a spring loaded ferAmic button dual disk
