Anyone who has done suspension, lift, wheels. Looking for feedback on 37" tires. What size lift & what shocks are you using. What else have you done on your build. If you have miles on are you happy with it or what would you change . Thanks for any input.

Check http://www.duramaxforum.com, you'll probably get better info there. Cognito is doing some really cool stuff for the new GM trucks.
