Hey what's up? Me and Brian have the exact same truck and want to do the same things, so I figured I would post what my door says for him so you guys could tell us what our gearing is. It's "RZN196L-CRPDKAB" and "BO6A/A340E" . I may have given you too many letters or numbers, but I thought better safe than sorry. Thanx for helping with the gearing question Brian and everyone who is posting.
