Looks like one hell of a set up but if u go 3.5 won't u have to replace drive shaft Danny put a nasty set up together there must be nice ha ha ha ha
I have the 3.5" (which gave me a tad over 4") and I'm still running factory shafts. No issues after 2 years, not to say I will never have a problem, just no problem yet after ~ 17,000 miles. One thing to note, the front shaft does not hit the trans as I have a manual not an auto.
