New clutch

Mulletman · Feb 10, 2016

Well it's time for a new clutch my original is slipping pretty bad. My mods are in my sig I likely have a little under 400hp or so. My question is what brand south bend or valair or ect.. Also should I get one rated for 500hp just to be safe? I likely will never reach that Hp although I will probably upgrade my turbo in the future.

I really like my southbend. I have the 1944-60K. Rated to 425 I think.

Smooth and easy pedal. Regularly tow around 10K and it has been holding up great.

I'll have to double check my part numbers, but I have a southbend clutch rated for 450hp and I hate it. It chatters and grabs, I find it very like a lightswitch. Definitely a pain in the butt trying to manouver my 5th wheel in tight spaces. My next clutch will be a valair and see if they're any better.

Based on some research I did a couple years ago, I think this is the one I was I'll be going with when the times comes. 1944-60FEK. It is organic on one side and feramic on the other side. I think the full feramic is significantly more "grabby". I'm interested to see what itwiw's part number is. I suspect it is the full feramic, but could be wrong.

*Edit*

Keep in mind the hp ratings are flywheel, so you need to add back in the 15 to 20% driveline loss if you know how much max whp your truck is making. This should be the perfect clutch for a 350 whp tow truck.

Won't let me edit my previous message, my clutch is 475HP SBC1944-6OFEK 7.3L 6sp which is the one I think you're looking at ja cain. I'm just not happy with it. On the upside, my wife hates driving it so bad since I replaced the stocker she won't drive the truck anymore.

I just purchased a spec clutch last night for my 4bt expedition. I contacted south bend clutch(1.5hrs from my house) and I wasn't impressed with what they could offer me. Spec builds clutches for a broad range of vehicles and with many different power ratings. I purchased an overkill clutch kit for my needs but hope to never have to replace it for a long long time. Might want to look at spec clutches.

Organic, full face, dual disc, 3200# pressure plate. It'll have a lighter pedal than any single disc, and you'll never slip it at 400ish hp.:thumbsup:

How much do those dual disks run? I don't want to cheap out by any means but also don't want to spend a ton

Mulletman · Feb 10, 2016

And I've heard both good and bad things about the south bends they seem to be what most people go with though.

I spent about 800$. Had the flywheel surfaced, on top of that, if I remember correctly. Plus a throw out bearing, couple other odds and ends.

Do you have a link to the one you got?

psduser1 · Feb 11, 2016

Sorry, bought mine through a local guy. I did pm you, mulletman.

Yeah, that's the one I was thinking of. I guess I may have to look into one of those dd organics.

:thumbsup: Agreed, at below 400, don't sacrifice pedal and engagement.

Neither brand, sorry. If you want indepth, we'd have to talk personally.

Ahhh....secret squirrel chit. Lol! I'll pm you sometime so I can get the number to your bat phone.

In all seriousness, I like the idea of running something different. Kind of like Shannon is doing with his 4bt. I also really respect your opinion, because I know you really work your trucks.
