Also, it would appear that they have a diameter difference. 6 1/8" for the Evo dampner, which is what my Fluidampr measures, and 6 3/8" for the DSM dampner.

Two links to places that supposedly sell the 610702:

http://www.full-race.com/catalog/pro...5og4dio17ur173

http://www.buyimportperformance.com/...9_p/610702.htm

Maybe it's an old/discontinued part # for the same thing? Somebody tried to organized a group buy for the 610702 back in 2007 on evom:

I'm pretty sure Fluidampr discontinued the aluminum units for whatever reason. Either full-race has not updated their website, or they actual have some of the aluminum units left.

There's your answer:

#610701 - Steel
#610702 - Aluminum

I'll call Fluidampr on Monday and see if I can verify this.



You don't happen to have a digital shipping scale, do you? Human sensory perception is notoriously inaccurate for estimating weight...

Digital scales are available for use (for free) at U.S. post offices with self-service shipping stations, and every FedEx/Kinko's. Just FYI.

I don't have a shipping scale, but I do have a fairly accurate bathroom scale. I realize shipping scales are much more accurate. It shows the Fluidampr weighing in at 6.8lbs, and while holding it, I weigh exactly 7.0 lbs. heavier. I do recall the thread about the aluminum units being discontinued discussing a 2.0 pound difference. So, I think it's about right.

EDIT: Here's the thread I recalled reading the 2 pound difference in... https://www.evolutionm.net/forums/ev...e-you-can.html
