I have an 05 GMC Sierra Z71. I bought it used and i'm assuming the torsion bars were already cranked up a bit because I have 305/75R17's now with no modifications to the bumper, etc.. Clearance is awesome. No rubbage, but the tread is almost all gone also which is why im bringing this up because i'll be putting new tires on soon. I notice my front end is starting to sag a little bit so i cranked up the bars each a 4 turns which helped but was also the max. The cheapest way would to put keys im assuming for more lift. Now by me doing this what is the downfall to this? Ride wise how bad will it be with regular autozone shocks.. CV Joints in a bind? And are their any strengths with this option other then money?
also... looking to get about 3" if possible with new tires. What size blocks should i add to the rear factory blocks to make the front slightly higher then the back?
I'm new to all this so if i'm asking for alot sorry. Just tryn to get alot of opinions before i spend money i dont have being a full time student on my own.
