    Well, it's about time to regear. I'll be running 35s soon and I need to know what to run (currently runnin 3.73s on 33s). I have a 350 and TH350. Since I don't have OD, should I run 4.10s? I want to run 4.56s b/c I plan on going up to 38s, eventually. thanks for all the info.

    this exact post is still on the first page. and a search would have yielded my extensive gearing/tranny options for the 35-37" tire crowd i did for MilpitasK5 not 3 months ago.

    not alot has changed since then.

    A buddy of mine runs the same setup you do with 4.56's. He likes it except with the 35's (his are actually 34" or so) he spins 3000 RPM for 65 mph. That is a fair amount of RPM, but if you don't do alot of highway, no biggy. If you plan on 38's I would say definitly 4.56's and just deal with the RPM until you get the new tires on. I run 4.56's and 32's but I have OD so it is tolerable.
