Okay guys my '08 SUT is hating me right now..I'm running a 4" rancho w/ a truxxx lift and 38" toyos. My stock gears, which I believe are 3.73's, aren't cutting it..what do I need to move up to so I can regain some power and help my tranny out? Keep in mind that I have the new 6-speed transmission and not the 4-speed. Help please!
