So I'm looking to do some mods to my 2005 H2 vehicle has about 95k on it Here is a list of things I'm looking to do and would like some advise.

6" Fabtech lift
new 20" rims with 37's
new exhaust (suggestions want something with some growl but not annoying)
supercharger thinking of a Magna set up

Is there anything I need to replace or modify so I don't tear stuff up or break stock parts. Might possibly be towing a boat

 

Only recommendation I can make is to go with a larger negative offset on the rims. I just went from stock offset ( -10 I think, rubbing on the sway bar) to -12 offset. I completely stopped sway bar rub but im getting a bit of wheel well rub at full lock. You'll be fine though with the 6" lift and 37" tires.
