Are GM rearends notoriously not centered?
 

I just installed a new rearend in my 68 chevelle. it is offset to the passanger side by about 1/8". I called DSE to ask them the best way to center the rearend considering im using their upper and lower control arms. They said the GM rears are rarely centered and there is typically less tire clearence on one side verses the other. They said not to worry about getting it perfectly centered. Can anyone confirm this to be the case with GM rearends? Should I expect to have it offset to the passenger side by about an 1/8 inch.

Yes, they are. Even the new vehicles are that way. Its not unheard of to have a rear end 3/4's of an inch off center in a GM muscle car.

Slo-Z is right. It is common to see them off center

Yup mine is over to the right.,.Drives me nutz

Yup.. I had to go with a 1.5" spacer on the drivers side and a 1" spacer on the passenger side to get 275/40 17's on the back of my Nova.

Yep, drove me nuts too. I had a 12 bolt that was off center to the right and my right, rear wheel was closer to the lip on the quarter panel than the left was.

My 12 bolt is off 1/4" also. I am getting ready to pull it and have it rebuilt.
My plan is to remove and replace leaf perches accordingly to center the
housing. Is this the best way to correct issue?

Thanks for all the feedback guys. :thumbsup:

it may be more than just the rear if you have a full frame car. my body properly aligned sat 1/4" closer to the frame on one side than the other. frame checked out on all measuerments, but they allowed for a lot of "slop".

this just makes things more complicated. I am about to narrow my rear end. Should i not narrow 3 inches on both sides? is there a chance I may need 3 inches on one side a 2 3/4" on the other, to get it properly centered? what would be the proper way?
