Default U-Joints needed, which type to get

I have found pricing ranging from $10 to $65 for these things. Some are greasable, some aren't. Looks like OE may be non-greasable per Napa's site. Some are anti-galvanic for use in aluminum yokes, is that what I should get? I have a 94 vette. I want the best I can get. I'm replacing the half-shaft u-joints.

I just did mine a few mothes ago, and used spicer.

I actually didnt bother replacing the joints myself.
I removed the shaft, and dropped it of at a driveline service company.

Picked up the same day. balanced, installed, and ready to go.
I think it was 130 bucks total.

I was shocked what a difference it made in the car.

Get a bushing kit before you do the halfshafts, so you can replace some of that stuff too.
Or you may have to go back in again to do it like me.

I found spicers at NAPA. Look for ones with the grease fittings on the ends rather than the valley. I wouldn't pay more than $10/$12 each, if that much...

Galvanic corrosion occurs when dissimilar metals are in contact with each other, such as aluminum and steel (Iron).
The Anti Galvanic u-joints are to help that situation.
The reason I bring this up is because the folks at the parts store usually do not now what Anti Galvanic means.
Hope this is of interest.

You must use spicer, cold-forged with NO zerk fittings.

Anything else is crap.
