I am going to put a moser 12bolt in my 68. I have heard that the mounting points for the uppers are rasied. I was wondering what suspension pieces everyone was running with this rearend? Southside lowers and adjustable uppers worked well for me with a stock rearend, would this setup work with a moser rearend?
Thanks in advance.

I have heard the same thing about the moser rear ends but this should be a good thing as this will move your instant center rearward which is what a Chevelle needs along with a good double adjustable shock. If you have adjustable uppers that will still fit you have the best setup made. An anti-roll bar might also be a good idea as the new instant center will hit the tires harder and may require softening the shocks. Do you have any front end changes? (Moroso springs, looser bushings, removed front anti-roll bar, etc.).

With the raised upper ears, that will naturally shorten the instant center. I would use the SSM bars, but leave out the drop down brackets. Simply use the SSM lowers as a stock replacement piece. If you tried to use the SSM drop down brackets along with the raised upper ears, you would likely find traction to very inconsistent due to a very short and violent instant center location.

The front end is stock replacement pieces. If it doesn't hook after trying to play with the tires and rear end adjustments I was going to try adjustable front shocks.

68Chevelle533, The Moroso high energy springs really aid in the weight transfer department. My son's 70SS clone has this spring and hooks fairly well.(generally around 1.40-1.45). It also helps to disconnect the anti-sway bar in the front and add a anti-roll bar to the rear end.

I'm using the SSM's bars/brackets with the Moser rear. So far I've have not noticed any problems as the car 60's pretty good with very minimal time spent tuning the chassis. Of course, I run on a well prepped track and haven't tried running without the brackets yet, so there may be some improvement left.

i have the moser with the metco uppers and ssm bars. i noticed when the bars were in the stock location the front wanted to rise better. i tried them both ways at the track and the stock location was worth .0014 for me in 60'. i might add my front end is pretty lose as well. Dave

Thanks to everyone for your responces. I will see if the car hooks first with the SSM bars installed without the drop (per Sheetmetal). If it doesn't hook then try front springs and shocks. I am hoping for 60' in the mid to high 1.4s.
