Three questions about a Southbend clutch for my '07, 5.9

[Motorhead]

Kinda looks like the stock clutch can only handle STOCK power or Smarty jr level 1. I NEVER tried the 100hp setting... ... HONESTLY!!!

Question 1) How noisy is the Southbend DD clutch?
I have to have the DD because I can't have a heavy and hard clutch pedal. I have a back injury and a hard clutch does me in if I get stuck in traffic. I need to hold 450-475hp. I don't drag race, sled pull, or see if I can pull some idiots truck out of a mud bog. I pull a 8,000 trailer. My mods will be Smarty jr mostly run on setting 2 but I do want to have the option to run setting 3.

Question 2) Where is the best price and service on these clutches? I will install myself (with help!).

Question 3) What will be the best combo without over-kill but capable of the HP I might run?
I looked on Southbend's site. this is the one I thought of.
South Bend Clutch Double Disc - SBC DD

SBC 3250 street comp 12CB sprung or rigid. Site says it will hold 550hp and have light pedal pressure.

I have the 3250 DD sprung hub in my truck, and love the darn thing. It has very light peddle pressure. I have the upgarded hydros too. I went from their 3600 DD to the clutch I have now, and it is a pleasure to drive now!! My 5' 100 lb daughter can drive it all day long ( if I would let her )

I have heard a lot of people are happy with that clutch.



I wish I would of bought it instead of my OFE.

I can tell you about the 3850# DD because that is what I have. It will hold 750HP and take all kinds of abuse. I have the hydraulics and the pedal pressure is about 1. 5 time stock and it is a noisy begger. But I wouldnt change it. I don't even notice the extra effory on the pedal anymore, somebody else drives it and thats their first comment.

I also have a 3250 DD. It is able to handle the TST PMCR max output with no problem.



It's somewhat noisier at idle, but I don't notice any difference compared to the stock clutch while cruising at highway speed.

3250

Motorhead, I drove MSchneider's '05 G-56 w/3250 DD. It has smooth off idle takeoffs and smooth downshifts. Approximately stock pedal pressure w/hd hydraulics. Noise inside cab was minimal. He's running a Bank's monster exhaust without cat so it was a bit louder at idle than stock exhaust. That would mask the chatter some. Outside clatter was not bad either. It's still not as loud as my '99 idling. Shifter shakes a dab more. I'm curious if a Fluidamper would improve the clatter more. He's near me in Santee. I don't know where you,live but it might be worth it to checkout firsthand.

Do any of you guys that are runnind the 3250 DD clutch have the dampened discs? Are you running the ceramic pucks?

 

[ENafziger]

The 3250 is a diaphragm clutch, rather than finger type pressure plate; thus, it will be much easier to drive on the street than the 3600, 3850, etc.

There have been many reports of the 3250 holding 800+ hp, and one or two at 900+.

I'm running the 3250 sprung hub version and love it.

i love my 3250 dd pedal is a smige harder than stock to depress. but be-ware that it is jerky taking off loaded. i pull a 15k fiver. ive pulled lighter loads around 10k wasnt as jerky with the 10k load. set smarty on level 10 clutchdidnt miss abeat.
