id cut 2 coils out of your 5305 springs and honeslty I think you still will be ok with helper bags.
Right now how low is your front compared to rear?
275 50 20 you can go easy 4 inches because on a 305 35 24 a 3/5 drop is fine and your tires are over 1 inch shorter.
2012 Very nice, hope he does send pics.
But for my Tahoe, im at 32" all the way around, im level all around. I have rear hardware kit. I don't have helper bags though.
What helper bags would you recommend, as i know nothing about those.
So i should be fine cutting 2 loops. Would my shocks need to be changed. They are bilstiens.
