Hey everyone I am new to this whole "modifying" your truck thing. I bought a 2016 GMC Sierra 1500 All-Terrain 5.3L. The only thing I have done is put a K&M CAI in and am currently looking at a leveling kit but want to upgrade to 33" or 35" (if possible) tires. I also want to hear everyone's opinions on modifications they have done to their truck that didn't break the bank and their favorite ones. Pictures would be beneficial too. Thank you in advance!
