Has anyone installed an Art Morrison multilink independent rear suspension into an E body (i.e. Cuda or Challenger)? I know these are not cheap, but all that I've read about them are that they ride great, handle gobs of power, and there aren't any noises that come from the rear end. My concern is how do they install in an E body and what is the process to a successful install?

I would like to hear the good, and the bad with anyone with any experience with Art Morrison's IRS.

Thank you,

Mark

I would say you would be better asking this question on one of the pro-touring sites, most of the posters in this section have stock based suspension systems.
If you don't mined what does a setup like that cost?

Art Morrison's stuff takes his frame rails.

From what I can tell It starts at 11,430 and that includes the rear frame clip, Suspension, S60 with gears, axels brakes.

Wasn't there another system like this out there? Heidts has one but there was another that I cannot remember the name.

Heidit has one as well, a guy here has it in a notch back barracuda , I'm not sure if it's on the road yet.

I did a search and didn't find any topic concerning this IRS suspension, so I thought I'd ask and start a thread here.

From what I can tell, the Art Morrison IRS is a multilink design of their own. It uses GM spindles, but the rest of the design is based on 3 years of development by the team at AME. There's also the Strange Dana 60 center section, so this IRS can take some serious horsepower as we all know what kind of punishment the straight axle setup can take. I did call AME and I was told that with the Dana 60 center section and the GM based spindles, this IRS can handle 1,200 horsepower out of the box without twisting up the attachment links. AME also told me that yes, they recommend that their subframe is used as the stock E body frame rails are not made out of thick enough material to handle the power. O.K., that's scary right there. The Dana 60 center section is what caught my eye as I was not crazy about the Jaguar based Heidt's setup as I know they are not known for being able to handle huge horsepower, and from the little bit that I've read about them, they are pretty noisy because of all of the heim joints. In a race car that's O.K., in a street car, well, at least not in my street car. I also didn't want to consider installing a Ford 9" in my Mopar -- I just don't want to do it even though I know it's a good crown and pinion -- not a Ford hater or anything, I just want to keep the car as Mopar parts friendly as possible.

Price wise I'm not sure -- I think it starts at $11,500 and goes up from there. Yes, I know it's a lot of ching, and I know it's going to limit how many they sell for sure, but I was just wondering if anyone else out there has done such a thing or knows of someone who is installing these in an E body so I can know if it's a total hassle or really worth it? I can read all kinds of reviews about this in Hot Rod about installing them in Camaros and other GM rides, but all of these articles never say anything bad about any new product, and I was just wondering if I could get the real scoop on this piece. It sucks to reinvent the wheel if someone else has blazed a trail and knows the answers.

If anyone can help me out give a shout.

Not gonna find any users here, I am pretty sure. You might find someone that knows someone that has it though.

Funny thing is that if I had the $11.5k and lets say another $1k or so to install that IRS, I'm not sure that I would just from all the downtime of having my car in the shop again.
I was all about installing every aftermarket piece out there a few years ago but now, not so much.
Even if installed I would imagine the handling would improve greatly, I am not sure if the fun factor would increase?

Very nice piece though

tom's purple valiant looks like a better and better deal AS IS every day as threads like this pop up. only a few dollars separate the items, and the valiant comes with "no sweat equity" involved !

It's a amazing looking suspension system and if you are looking at competing at the top level of the pro-touring world it is problem almost mandatory at this stage. For me if it got to the point that I wanted to go that fast I would just buy a new GT 350 and leave my old cars at a reasonable level of performance.

At what point does such a modification produce "greatly improved" handling or ride is what I think a number of people would ask. Similarly, since it comes of regularly in this forum, what rule legality issues would such a huge change from stock create.

For real world feedback on such a conversion, ask the Camaro crowd over to protouring.com. No doubt several of them have already attacked such a conversion.

i know i should just buy that car, its so cool. great little ripper.

That suspension looks like a work of art by fabrication. I wonder what it does to overall weight and track times?

I personally would be more likely to spend my time and money on massaging the body for bigger rubber, aero improvements and HP.

It costs 12K so it must be awesome. And the 250 lbs it adds only makes the handle better to.

I would say the biggest downside is the added weight, besides the cost. I would also say while I have been pondering a mopar IRS set-up for years, I would say this one is likely one of the better designs compared to other vendors decades old Jag/vett iterations, IMO. The choice of a Dana 60 also IMO is odd, a viper does pretty well in handing situations with a much lighter/smaller alum dana 44. I would guess they might in future add to the center sections offered. The price point would serve them better if they could get it to the $8K range, again imo. It has been well received by the few using it on the PT scene that I can see, but not sure ithey plunked down $12K either.

I would say that suspension might add some weight, but I would guess at the most 50lbs over a dana 60 with leaf springs.
The price is $13800 ......I priced one out with the exchange rate to Canadian dollars, shipping, border duty and GST and it would cost me over $22000 Canadian to have that thing sitting in my garage.

Just do it, then! When will you have the opportunity again? That's what I told myself when I bought the Red Brick.

I was strongly debating it and considering making the plans when you did too. Lol.
