Different supercharger coupler measuerments.

I've ordered two different ones as I wasn't impressed with the quality of the Dorman one, and they are not identical so I took some measurements with my calipers.
Feel free to add any measurements you can of the ones you have on hand, especially if you have a stock one handy, or access to a snout to get the pin size and spacing measurements before I get to them.

BRAND -THICKNESS - OD - ID - HOLE DIA - HOLE SPACING (center to center)
Dorman - .595 - 1.953 - .762 - .250 - 1.292
eBay - .633 - 1.958 - .752 - .248 - 1.305 (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&vxp=mtr&item=251483211585)

So the only real difference is the thickness so far.

Spend the coin and get one from ZZP and never worry about having to replace it again.

I'm not sure I buy that theirs is any better than any other. However...how many of us ever leave something alone for long enough to find out if they would wear like stock?
 
True lol but there seems to be a few guys from what I've read that had issues with the Dormans. I didn't want to chance it after spending hours getting those stripped torx bolts out so I just spent the coin on ZZP and compared to the Dormans seen to be way better quality. Oh and OP replace those torx head bolts on the SC with something else.


Edit: and I rarely spend money on ZZP products.
 
Yeah my coupler was replaced about 53k ago by the PO at a shop (work order was in the car when I bought it), assuming they used OEM. As far as I can tell it doesn't NEED replacing now, but I will anyway when I change the oil so I won't have to again. I don't plan on using the Dorman one, it just doesn't feel right.
 


i got a green one off ebay for 20 bucks. its over 3 years old now and is just fine still. i had to tap it on the pins, its holes were very tight to the coupler.
