I know I have read threads on here about this but I can't seem to find any of them.

I am looking at having to replace my transmission and if it has the small input shaft then I will have to get a new clutch to go with the updated larger shaft.
If I have to replace the clutch for an nv5600 which would be a good choice? I pull a trailer (about 3-4K lbs) nearly every day. I would like to run the Diablo Puck and have some room for a little more power. I want something that will hold up for many miles if I keep the truck for a few more years.

Thanks

 

I had good luck with the Mcloud until i broke my input shaft and messed everything up, it was the dual disk street, but i stayed with the small input shaft which was a dumb decision on my part but at the time i had a small student sized income...

 

I have a South Bend Con OFE and I don't tow everyday, but when I do tow it is fairly heavy, my empty trailer is 5000 lbs.

Yours not only has the small input shaft, but also has the smaller 12.25" clutch. Under no circumstances would I put the smaller diameter disc back in.

 

If I upgrade everything from the smaller components to the larger components, do I need to buy a new flywheel as well??

 

South Bend Con OFE.

 

You should have a 1 1/4 input and a small flywheel you will want to go to a bigger input and flywheel 13" valair for me.

 

valair hands down

 

SB the only way to go.

 

ha ha so I guess valair or SB has the split vote. This "repair" is going to be $$$$!! Hind sight is 20/20 but I now know that I bought the truck from the one year I should have avoided. Oh well, after all this is upgraded I just need to find a D80 with disc brakes and I'll be in business!

 

Do your research before you purchase is all I will say. (word is if you get a bad Valair, you get an SBC anyway.. )

 

I say do your research in multiplie places, talk to both companies and form your own decision both are very good and have very loyal customers.

 

my valair was the best upgrade i have done on my truck. ive had it in for three weeks now and love it. it holds everything i can throw at it as of right now.

 

Valair has been banned from this forum because of their business practises, nuff said

 

I went ahead and got a SB...best choice I've ever made, I abuse it a bunch and not one issue so far!!! (you may have to upgrade yer hydraulics) I used to purchase by price alone but I've long since learned you get what you paid for!!! I had the "rebuilt" tranny out for replacement after 10k, (DON"T BUY FROM SOUTHERN DIESEL PERFORMANCE!!!...PM me for details) there was virtually no wear on the clutch or pressure plate!

 

south bend con ofe works very well for me. don't tow often but do tow verry heavy when i do
