Re: Khaos' 2004 GMC RCSB Thread
Got the 4* shims in this afternoon with 2" longer ubolts from SD Truck Springs. Definitely helped with the pinion angle vibrations I was getting. I ran it on the highway up to 100 and it only started with slight vibrations above 90.
Overall I'm happy with how it is right now as I won't be going 90+ mph often, if at all.
I'm gonna keep the ss 20s and run them this season I think. I'm ready to put some real wheels on this thing :crazy: Other than doing that, a rear sway bar will be bought at some point and paint for the bed & color matching. That'll be it for this year on my budget.
