Saturday was the first time I pulled the truck with all the mods. I tried 3rd on the low side and it took off and then about 80ft I smoked the stock clutch. This truck is really strong now!
I have called about 6 diesel shops that sell South Bend clutches and 4 out of 6 recomend me doing the NV 4500 Conversion. I don't want to spend that kind of money right now and buy a South Bend pulling Clutch.

Will the Getrag hold up to a South Bend 3600 pulling the sled with my mods?

Chuck at New Era said he could change the spline center out if I went with the South Bend for the Getrag and it busted for the NV 4500.

 

From your sig you're running the stock turbo and 435 sticks? How much NOS? I think you'll likely melt the engine down or munch the d70 (locker or no?) long before the 'rag gives it up. JMO.

 

Yeah It is a stock turbo. I am looking for S300. I ran on Saturday a 70hp shot of NOS to cool it off but that wasn't enough. They said I had a flame coming out of the stacks and the egt got up to 2,000 +! I am going up to 130hp shot to cool it .
Thanks

Well I say go for the NV4500 because I'm looking for a spare Getrag for mine. I think both have there problems.

 

Unless you are going to a 4500 with the 1-3/8 input, you can use the same clutch when the gutbag gives out.

 

Keep the Rag. It is cheaper and you dont need to do a lot of custom stuff. The only advantage of the NV is the available upgrades.

 

You are runnin a bit more power but I am pullin with a getrag and a 3600. Those stock clutches are crap for pulling. Just get the 3600 and keep the getrag.

 

Tank, How long have you had the 3,600 SB? What gear do you pull in also?
Appreciate everyones info, It's giving me more confidence in the rag now!

 

I have had it sence last aug. 07 I have hooked it 8 times, does pretty good. I pull in second hi with 4.10's and 33's. I was always told first and second gear in a rag is tougher then in a 4500? I usally pull 290 ish which is enough to beats some newer stuff. Keep me posted how you do.

 

I ran the getrag for 2 years, after I overhauled it. For the $600 I put into parts at that time I guess I got my moneys worth. It isn't a bad transmission, but I know where I was headed it would not be able to take me.

However, I found a lot better deal 2 years down the road on a spec built NV4500 so I bit the bullet. It made the dual disk swap easier, the gear spread is a little better, and the throws are shorter.

Every transmission has it's pros and cons. You have to decide what your budget allows and start there.

A first gen with a dual disk really turns heads in the pits at a pull, that is for sure.

 

yeah last yeah I burn't the stock clutch then put a napa clutch in and burnt it at the pull so the next pull had double disc, just told the that noise was a bad throw out bearing from the napa clutch ha!!

 

Gotta keep the competition guessing.
