Im looking for a independent rear suspension set up for a nnbs. I'm looking into the vette set ups and see the Dana 36 and 44. Any suggestions, I'm making good power and plan on putting 4:30's in it.

 

Why are you wanting an IRS? Just curious

 

Im bagging my truck and planned on raising my bed floor. If I run IRS I won't have to, just have to put in bigger tubs. I think I can do it for the same money if I have to raise the floor.

 

Don't do a Dana 36. Fast 80's and 90's auto vettes tear them up easily on the strip. The later manual C4 vettes had dana 44's and they were desirable for the strip cars.

But we are still talking about a truck having hundreds of extra pounds at a minimum. I also don't think you could put a 4.30 gear into a Dana 36 vette diff anyway.

 

Power + weight + IRS = boom. Unless you get a high end IRS you will prob have issues, not to mention if you plan to run that low, axle to wheel angles will be out, could possibly cause issues there as well. Not trying to **** in your corn flakes.. Just things I see being a issue. By the time you do all that you will have just as much time( more money) and effort in set up with a standard rear axle.

 

Probally have to use somthing like out of a 04-06 GTO as those are not very light....

 

They way I see it, if you are setting the center housing up so you don't have to cut up the bed floor, then if you ride low your axles are going to be at horrible angles. Its like when lifted trucks with ifs go to high without dropping the center housing their angles are horrible and they bind.

The proper way if you choose to do an irs setup, IMO, is to set the center housing where your axles are straight at whatever you want your ride height to be. And assuming you want the ride height low, your still going to have to cut the bed floor.

Also note that more than likely the only thing you are going to use off the rear end is the center housing and hubs/brakes. Most build a cage for the irs, control arms, have axles made for their specific length, etc. As you can imagine, all of that is labor intensive and can be costly if someone else does the work.

Keep your solid axle and do a stock floor body drop on the bed. Literally raise the whole floor for your clearance. Looks "stock" other than not having as deep of a bed

 

Raised bed floor is what the original plan has been. I've done a lot of measuring and will only have to raise it 3" so I think hats the route I'm gonna go. The new cts-v center section seems to be the best option for the IRS. Im just weighing all my options and a IRS would be ****.

 

You might want to consider a rear end out of a Thunderbird since you will have to make it work anyways.

 

The Fast GTO's are using conversion kits for ford IRS 8.8's and 9 inch rear centers.
