Thanks for the video, those allen bolts are locator bolts, they assure the floater plate is in the proper position when disengaged. If the floater lifts too high or to low it has drag. We actually cause an over lift condition and then bring it back to correct position with the allen bolts. Thanks for the business we appreciate it. Dan
I put one of the first runs of Valair double disk clutch set ups on my 02-2500 with a 5600 maybe 12 years ago. There was no silent model. It’s still going with 230k miles on it. I tow almost every day, my truck is mildly modded at about 425hp. It gets chattery when it’s humid out, but I have manual front hubs so I just put it in 4 low. I’m a home Reno contractor so I drive local. My truck is spent, looking for a new to me truck, has to be a manual, after seeing this, I’ll stay with valair. Thank you for putting this together.
I had a southbend street dual for about 90k miles. Hard to get into first and reverse and very slow shifts. I thought it was normal. I was bias to southbend because that’s all I ran but was afraid to try anything else. I just switched to the valiar quiet dual paired with a fresh rebuilt nv5600 from Andrew and I didn’t know it was possible for a dual disc 6 speed to feel this good. Feels like a brand new stock truck, even the pedal feels stock. The transmission will shift faster than I can keep up with. If you want the best shifting manual trans go with a valair with a LRG built transmission behind it
Extremely excited to hear that as I will be making the switch to 5600 from my 4500. Running a SB 3250 and have the exact same symptoms you mentioned. Hope I can give Dan a call and figure out a good clutch to really bang gears .
@@Samver85 200 miles on my organic val dd-- no noise at all, in my nv4500. I had no complaints with the SB single disk in this truck-- only replaced because the tranny was getting rebuilt. This clutch is a bit grabbier in first that the single disk, but i'm fine with that.
I think you just convinced me to go with the valair dual quite organic. In was set to buy the valair hd single organic for my g56, but maybe having extra capacity will be nice. My friend who owns logging trucks said his semi tractor units have dual discs and he figures you get more life because of the 2 clutch discs. He bought the valair quiet dual organic for his g56 truck.
Thanks for reinforcing my choice to go with Valair. I was seriously considering a southbend when it came time to replace the clutch. After much research and seeing many dissatisfied southbend clutch customers, it made it a rather easy choice.
I installed the super street from south bend. Couldn’t be happier. Harder clutch pedal but oh well. I couldn’t find a dual disc Villaire that would hold the power I need which is north of 750 hp. South bend has that option.
Great video. Just wanted to say that more facing surface area does not mean it will hold more. Yeah, there's more surface to grab, but the psi is lower because of the higher surface area but same total force. It probably means it will last longer though just because there's more material to wear away, and is less likely to experience negative effects from heat because there's more surface area to absorb it.
installed a south bend dual disk in my nv5600 after upgrading the hydraulics. I probably went overkill making sure I broke the clutch in properly but during the break in period I 100 percent thought I was going to hate the clutch. but after breaking it in and putting a few hearty miles on the clutch everything seemed to start working perfectly and I love it plus not near as loud as everyone makes them all out to be. if I need to replace the clutch again ill give a valair a chance.
That’s super interesting. Thats for sharing. I’ve been running a South Bend 3250 since 2008 in my 01 Cummins 6 speed. And it’s always had problems going in to first and reverse. Maybe it’s time to try something new.
I have a late 2nd gen Cummins with the NV4500. I plan on either having my transmission professionally rebuilt or buying a good reman unit. The Valair clutch sounds like what I’m looking for: smooth, quiet, and durable.
My original RAM clutch last 72,000 miles towing. Now I have the Valaire dual disc ceramic - organic quiet clutch. It is quiet. Not as quiet as the stock clutch but I am very happy with that as I’ve heard other clutches that are not. My complaint is my truck shifts terrible now. 1st, 2nd, reverse.. terrible. This started with the mistake on the mechanic installing. Valaire was great in their service, but according to their instructions the clutch should start to bike at 2-3” off the floor. At that adjustment shifting is terrible. However I do have a workaround so I’m no longer stuck at a green light. I shift into 4th, then 2nd and 1st and everything works find with that small workaround. The clutch is solid. Like the other commenter having the SB my shifts are also slow. I have no regrets about getting the Valaire but I have no personal experience with SouthBend.
My last clutch was a SB 3250 in my 05 HO with a 5600, after watching this im gonna try the Valair DD org quiet in my 07 G56 Dually instead. Whatever is in it now is awful, extremely heavy pedal and instant on/off, There is no smoothness even when making rolling shifts. Makes driving the truck more of a chore than an enjoyment honestly.
I switching to valair so I’m kinda anxious to see what happens? I’ve always use South Bend clutches and I’ve always had 3500 Cummins so best of luck to me
Thanks. Wish they had a 2 piece throw out bearing lol. Change without pulling trans. Lol might have to replace 2 more times. . . And can you Re torque 5th gear nut lock without pulling trans if that’s your only problem. But taking off transfer case pulling trans not 2 much more. But I’ve done surgery blindfolded . Lol
I’ve never attempted to retorque in the truck. I torque them while fixtured to my bench with 4th and 1st gear applied simultaneously. You can’t do that with the top cover on, so the engine would have to hold the shaft and I’m not sure it would…
I've had three SBC's over the years (Con/ofe). That's not because they wore out, that's because they failed one way or another. The last one came apart internally and jammed itself engaged earlier this year. SBC wouldn't even give me 10% off towards another clutch. I have no knowledge of Valair but that's who I'll get next time.
I got the non quiet dual disk Valair clutch. It does make some noise. I do have pretty slow shifts with it though, also hard to get into first and reverse. Makes me wonder if it’s dragging a bit.
Wondering if you would have a solution to my problem (and if its the clutch then ill be buying valair which i likely will already because my south bend shifts like garbage). I have a 12v cummins with a nv4500 i rebuilt with all high quality parts, with the south bend organic/ceramic dual disk and upgraded input. I have a np241dhd and dana 80 disc rear end that was recently rebuilt. Last year i got a 5" aluminum driveshaft made because my slip joint failed on my stock steel shaft. The aluminum shaft amplifies a god awful rattling sound that i compare to a concrete saw. Its significantly louder than my exhaust under load, especially in 4th. Would swapping to a valair eliminate this sound? Its unbelievably frustrating to spend $3k (canadian) on a clutch and $1500 for a drive shaft for it to make my truck sound broken all the time. Yes, we get absolutely screwed on cost, its Canada.
I'm curious on what your take is on exhaust brake use both with how affects clutch life and transmission life? I'm currently stock 305 hp nv5600 with the stock clutch at 100k miles
Zero problems. The stock clutch in the NV5600 lasted way longer than the garbage they sold in the G56's. The exhaust brake will not cause any problems as most of them create about 165bhp. Which is nearly half of what the engine puts out. I will say to avoid the dual disk clutches. They eat pilot bearings.
@@kyles234 the pilot bearings are extremely reliable in dual disc kits, they’re rated far beyond the working RPM’s they see regularly. If you’re eating pilot bearings, you have an alignment issue. Verify all dowels are in place.
@@longrangegear nope. The pilot bearings fail because of the additional vibration from the dual disk setup. Got 430,000 kms on the current single disk. Could never get more than 100,000kms from a dual disk. Both south bend.
@@kyles234 I’m sorry, but that’s just not the case. The load and rpm ratings for those bearings far exceeds what they experience installed in the flywheel. Even in the event that would be the case, the bearings are less than $15 and press in easily. Nowhere near cause to remove a dual disc and lose capacity.
I have a NV5600 on my 2005 Dodge Ram 2500 4x4 5.9 diesel . It has a South bend Duel Friction and the throw-out bearings makes a dry grinding sound . This is my second Throw-out and from the start the second one makes the same dry grinding sound. The mechanic said he thinks it is . So now after seeing this video maybe its time for a change . I load a 3,500 lb camper and pull a trailer that when loaded is about 3500 lb . Which Valair would you recommend for me application ? So tired of the grinding sound every time i put the clutch in . People look at me and its embarrassing What would the price be for the Valair ? Thanks
I have the same issue with a non quiet Valair dual disk clutch from new . The throw out bearing was greased so I guess it’s just how it is. I know what you mean though it’s a bit annoying.

Also why you must tighten by hand and the torque to spec, over tightening those will cause diseiissues. Use Loctite
Hey guess can you explain this a tad bit, this will be my first time replacing a southbend whatever to a Valir clutch
Valair FTW.
Been supporting them for 10+ years now.

I thought it was just me--- SB in my 5600-- first gear and reverse is a pia. I have to shift to 3rd (clutch in) then first or reverse. Grrrrrrr....
What about the noise on the Valiar DD? My SBDD is very noisy, I’d like something stock quite.

Never really seen anyone upset. Other than noise I’ve also met 3 people who had the straps on those valair quiet clutch’s break. Good luck.

You can adjust the pedal until the shifts are smooth, use valairs recommendation as a starting point.
Just float the gears.

Sounds like your hydraulics are giving up, or youre low on fluid for the hydraulics.
All comments about the south bend are very true .
What about just regular single disc for stuff that’s making like 400hp? Does it just not matter as long as you go with south bend or Valair

Does it come with ballbearing pilot bearing in flywheel?
Is the quiet version offered for the (2002) 7.3 and ZF6 combo?

$1345 as of today 👍
how much is shipping?
