considering bolt ons,some info for you

if your budget is tight and you want to add some bolt on's to help your track times consider this, my car weighs 3400# and i'm pulling 1.24 60' times with bone stock LCA's and pan hard rod. my buddy just pulled 1.239 with the same only he has boxed his LCA's. just a thought you might get more bang for the buck elsewhere.

Your 12-bolt doesn't hurt. What tires are you running?

more bang would be 12 bolt and slicks... but thats hardly more for the buck.

i'm running M/T 28x10.5x15
definitely helps with a good rear end. the moser posi unit held up for almost 3 years. switched to a spool last month.
