I would say that suspension might add some weight, but I would guess at the most 50lbs over a dana 60 with leaf springs.
My guess is a whole lot more, are you forgetting the frame clip needed for the IRS?

I would think that it would add weight in the right area though as most iron block cars are what a 60/40 split front/rear? This IRS may just make it easier for a car to be 50/50. Too bad it takes a lot of mass off the wallet as well haha!

I'm just guessing off the last dana 60 I moved still had the leaf springs and all the hangers, u bolts, shocks, ect attached to it. All that stuff must have weighed 300lbs, that IRS setup and associated mounting hardware can't be that much more. I could be wrong but I don't think I'm to far off.

Too bad it takes a lot of mass off the wallet as well haha! Well, if adding weight to the back to get 50/50 is all that you're concerned about fill the trunk with concrete. Yeah, I know foolish, but putting a heavy rear suspension in to accomplish the same goal is about as foolish too. Now if the heavier rear suspension markedly improved the handling and ride, and that is the question at hand for an E body here, then go for it. But less weight generally helps handling more than increasing weight. I don't know where y'all are finding prices and weights, but the picture I see doesn't show brakes or shocks or springs, which will add to the weight. I also don't know why one would compare it to a stock Dana 60 setup either, not what I'd choose in a handler myself. In fact one could make a very cogent argument that the 8 3/4 is a better choice to ease gear changes for different type races and lighter in weight and most like more than strong enough for a handler.

I agree on all your above points on the AM IRS.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

I was comparing it to a Dana 60 because the Art Morrison IRS uses a Dana 60 or strange 60 centre section. 8 3/4 rear ends are great for a decent horsepower street build but I think anyone looking at this IRS would be looking at putting some big power through it, as it is rated a 1300RWHP.

I don't usually equate 1300 hp with a handler or enough HP to frag an 8 3/4 for that matter, at least not in this forum. A blindspot perhaps. I dunno how much dead weight this unit might save over a normal Dana, but unsprung weight I can see.

Its sprung weight, and anybody that can put 1300hp to the pavement successfully in a handler is not on moparts, that is way beyond anything we can even dream about. Few if any chose an IRS for drag use, so that would not have been their market design target. A 9" or QC would have mt first choices if I was in their shoes. Strange.

It costs 12K so it must be awesome. And the 250 lbs it adds only makes the handle better to. Couldn't have put it better myself! Interesting how the magazines almost never tell you about weight INCREASES from the latest gadget!!

How many of them have jumped from a Mopar rear suspension to IRS?
because comparing Ford/GM rear suspensions is moot.

Here is the message from the horses' mouth: "The AM its added about 40 lbs over the 3 link with floater. I don't know about leaf vs 3 link, but the 3 link has less Unsprung weight. You can feel it even driving in a parking lot! Somewhere I have the 3 link weight. I think the leaf springs are 45 lbs each, most of it Unsprung."
So long and short, 40 lbs of sprung weight all in the rear. Not a bad bit and I'm thinking with the new Alloy housings hitting the market, maybe a few more lbs could be lost.
I don't really think the difference between GM/Ford Mopar makes a whole bit of difference, as the weight differences shouldn't be too more varied that the half dozen spring and rear options we all have. Everyone is going to be a bit different from 8.25's, 8.75's and Dana's. Not to mention 3 leaf packs, 7 leaf packs, etc.

I think he was suggesting the geometry of the mopar leaf system is better to begin with when compared to GM/Ford, not any weight issues. Furthermore, I suspect dialing in/adjustments with an IRS vs a 3 link, would find the 3 link much more adaptable. IRS IMO would shine best with unfortunately the more complicated and heat sensitive inboard brake set-up, not offered yet, as I can see. I would also guess some of the AM IRS weight gain could be mitigated because it is first a somewhat universal design, and therefore needs beef to be a solution for all, but I might be wrong.

yes. the geometry.
If your source is comparing the handling of a GM/Ford coil sprung 4 link setup then yeah I can see why they are impressed.

We also have to consider anyone spending big bucks on this type of setup will automatically say how great is is (smart they were). Bucks = happiness for many. We all work hard for our bucks. Now if an actual heavy hitter racer who had driven different setups in the same car would say WOW! what a setup, then it really holds some weight for me. So many times I see the average hot rodder wanna be say good things about their new toy. The more expensive the more they overstate. Just human reaction for many. I get it.
Bought a set of Fox 2.0 shocks with the resivours for my 2006 Ram 4x4 diesel. Hundreds of positive things on the net about ride improvements on road. Just installed them. The ride is super stiff. The tire leaves the road on small sharp bumps and sometimes the truck moves sideways. Scary. I have to pay attention at all times just in case. Great more stress in life:-( Can't wait to take them off and send them back.
NOT saying this is one of those things but i'm in my skeptical corner.

Supposedly custom for Thuren. Did you couple those with his coils? If not email him and tell him they suck, and let him make it right.
