3000 rpm at 70? Yikes, sounds kind of high. But what do I know...

Missoulatj Is it a manual or auto transmission? (I couldn't tell from profile) If its an auto wouldn't 4.88's be a better choice then 4.56's with 33's?

justin_brown Are 4.88 to low of gears for 33s?

Jerry Bransford 4.10 isn't ideal for 33" tires (my previous TJ had that combination for a while) but due to the expense of regearing, I'd wait on regearing until you go to 35's.

justin_brown My jeep is a rubicon so from the factory it came the 4.10 gears.. I mihht eventually go to 35s.. just with 4.10s and 33 I have a lack of power

So it was already regeared from the factory 3.73 to 4.10? If so, though 4.56 is optimal for 33" tires, I wouldn't suggest regearing would be worth the $1300 or so cost of regearing unless the cost is no problem. If you someday plan to go to 35" tires, that would be when it would be worth the $$$ to regear to 4.88.

jasongind Are you planning to never go bigger than the 33's?
