all right guys my stock clutch is fixing to take a dump on me. its really not liking the performance setting on the bdtd with the 285's. so i'm going to get a southbend because i don't see any point in wasting my money. as of right now i plan on getting the SBC DD 3250 Street which is a 600hp dual disk clutch. my goal is to eventually get to 550 rwhp. i also tow pretty regular. what do y'all think? am i going to have any problems with slipping or wearing with it? Thanks

by the way i don't know anything about performance clutches.

 

If u wanna dual disk that one is gonna do ya fine, make sure u get the sprung hub DD3250! U shouldnt have any issue with slipping or wearing with that setup. Might take alittle to get use to! Just my $.02

 

I have the 3600 springs and I tow heavy 90% of the time and it works great. Their is a little more pressure on the clutch petal, but no big deal.

 

am i going to have to upgrade the hydraulics? if so what all does that involve?

sorry it takes so long to get back. for some reason my computer at home won't lemme on here so i have to wait til i go to work.

 

I think that SB recomends upgrading the hydros on that model. Upgrading the hydros is a pretty simple process. 2 bolts hold the slave cylinder in. And then just pull the clutch master cylinder outta the firewall. As far as mounting the resevoir I just zip tied them to the ac lines instead of drilling into the firewall. Overall the installation took me less than an hour doing it by myself.

 

Loving my Sprung DD... You wont regret it... I wasn't overly impressed with the upgraded hydros though... Didn't really notice a difference??

 

You fried your clutch only running performance or did you have Crazy Larry on it at 1 time?
Mine's holding up so far quite well running 'extreme'.

 

zip tied hydro upgrade....... on a expensive DD setup, you think SBC would make it easier with a bracket or something nice for the few hundred it costs]

 

Amen on a nice bracket..~!

 

Mine is zip-tied to the wiring harness on the firewall. A couple of sheet metal screws and I could have it permanently mounted but that would take effort....

 

I like how the upgraded hydros have steel braided lines. A little pease of mine that thay won't blow out.

 

yeah but i also have 2 extra tires than you on the back and that is why i think the clutch has started slipping, because it was fine before i added the 285's. i'm also sure that it being hooked to a trailer that is over the gvwr pretty regular doesn't help either.

oh yeah no crazy larry

 

Well I think I was in your position about 1 year ago...

There is give and take on certain clutch set-ups. A stock single disk is set-up to be very divable, sacraficing wear for easy of use.

The SBC singles use special material to make their clutches grab quicker and overall wear slower than the stock. The cost of doing business with the SBC singles is they tend to be grabby, but some learning can help to mitigate those issues.

The SBC dual disk is set-up for high horsepower applications with a little more sacrafice in drivability. They are designed to hold lots of power, but the cost of doing business is the cost, upgraded hydros (more cost), rattling noise, esp noticable in the G-56s more so than in the NV 5600, and extra pedal pressure. Talking to most the quality of these clutches are excellent, but you do pay for it.

I have had both the 3600 and the 3250 DD. Honestly they hold great. There is a learning curve trying to back a heavy trailer with the clutch, as well as a little difference in clutching. First/second is sometimes sticky to get into gear. The clutch hasn't slipped with my 35s and the Smarty on Level 9. However, the rattling takes some getting used to. First DD I had was extremely loud, enough where some thought there was something wrong with the truck. The second DD is quieter, but still rattles. It can be fixed with the Fluid Ampr, but for an extra $500 I am holding off, for now...

For the rhosepower you are talking about the singles will hold fine, but if you want that extra step of insurance and pay some more money, than the Dual Disk is for you. Of course, like I said with every step there seems to be a cost, but SBC has done a good job of creating some great options for these trucks. Hope it helps,

 

I just have the OFE single but I agree with the last post. You do have to learn how to drive the truck a bit differently. Well worth it for the peace of mind though....

 

Wonder how much harder/slower the shifts are with a DD?
