Any one have experience with this or more snake oil?
Rattler

Looks promising though pricey.

I don't have any experience with them, but I have wanted to try one for quite some time. Seems like it would work very well.

Made in my home state of Mississippi. I'll give this guys a call Monday, see what all the hoopla is about.

One of several designs of aftermarket harmonic balancers.
Does any work better than OE? Maybe. Likely for racing build engines.

see also www.fiero.nl/forum/Forum2/HTML/133877.html
likely made for v6 too.

warning that made for X engine might not be exact replacement for OE stock...
if the "flange" area where pulley are mounted move in/out, even a tiny bit, then you must re-align the pulley(s) or you will have belt problems.

Having never seen an actual 88' crank, and asking a fellow member about their own 88' crank upgrade on a built 2.5, does the 88' crank essentially have this built in by cast for the DSI?
Or am I not understanding what was said? I apologize for the ignorance, still learning here and taking my time to pick components that will work together.

Ogre, edfiero also brought that up, I called the company, they said it should work. Luckily Summit has a good return policy, and their info does not specify which of the 2.5 engines.
So I may have to try it to find out, I will double check their return policy before ordering if this turns out to be the case.

87+ duke? won't work. Balancer IS the pulley.
Look up at rockauto etc for DORMAN Part # 594027 and others.

older duke... unless is small enough to fit inside pulley, won't work.

Crank uses simple hub to mount the pulley. example ATP Part # 102193
