Default Opinion on Valair Clutches......

Ok so I just got a $700 check for whatever and Im debating what Im going to spend it on. Options are body work, rims, studs, GSK, clutch, etc........ all which will be getting done in the summer but I have some stuff to buy now. So I was thinking about going ahead and gettin a clutch which would allow me to go ahead and mess with the pump some

So I have about $5-700 to spend on a clutch, preferably closer to $500 so I could put a couple hundred back for a rainy day. The most mods this clutch will see are the mods listed in my sig, pump work, 5x.014 injectors, 62/65 turbo, and 4k GSK, so no more than 450rwhp. Before I do any more mods (compounds, DV's, etc.) it will get a South Bend dual disk.

Truck will never see a trailer, this is just a play truck, so a strong single disk will work for now. Here's what Im looking at:

NMU70119-04 Valair Clutch Kit 1994 - 2003 Dodge NV4500 5 Speed

Its a Valair 12.25 full ceramic cluch with a 3800# pressure plate, and is supposed to hold up to 550hp and 1000tq, well short of anything I will ever throw at it. And I like that its only $500. I know a full ceramic is going to be very grabby, but like I said truck will never see a trailer. Do you think this clutch will work well for what Im going to be doing with it?

My other option is the exact same thing but in a ceramic/kevlar combo. Its a bit more at $650, and a bit less hp at 450/900, but it is supposed to be a better behaved clutch. Here it is.

NMU70119-06 Valair Single Disc Clutch

For my budget and power goals, what do you think is my best option?

---AutoMerged DoublePost---

Ill go ahead and make a note that the other option Im toying with instead of a clutch is 4k GSK, 60lb springs, mighty diesel head bolts, and 16-17* of timing, with maybe a little pump work.

A full ceramic is extremely grabby. Id look at a Dual Disc.

but do I really need to shell out for a dual when Ill only be running a max of 450hp and never hooked to a load of any type? It will be MANY years before I do any more work than this to it, and funds are limited at the moment.

and I have been thinking about the same thing about the full ceramic how about the 13" ceramic/kevlar combo? Its 500/1000 and is supposed to have really good manners and excellent for towing.

The problem with a single is they may hold the power when fully engaged but they do not stand any amount of slip. I wasted enough singles trying to just get by.

Alright thanks dude. I think for now Im just gonna buy the 4k GSK, 60lb springs, and head bolts, and then see how much I make this summer and try to get a dual disk then.

Can't go wrong with a high quality dual disc.
