Gears for 24's???

[lowreese26]

Hey guys. Need some help picking gears for my truck. With the 20's it was alot faster. now with the 24's it has lost a noticable amount of get up and go.What do you guys recommend? was thinking going from the 3.42's to 3.73's. Will I notice a big difference or not enough to be worth it?

usually tire height is what changes the rear gears. If they are alot heavier though that can change things. it's not a big difference really you are going to from 42's to 73's but then again it's not a huge jump in tire size and I think would be a good combo, should put ya right back close to where you were.

What is your overall outside tire size?

 

[lowreese26]

Not real sure if I know how to measure right. But from the ground up the center of the wheel to the top of the tire is about 30".

that's about the right way lol. close enough for sure.

Do you know what the tire size is? Here is a good tire size/height calculator: http://www.rimsntires.com/specs.jsp
That should give you a good idea of difference in size between the two!

I have some 305/40 22's on our 2DR and it has 3.73's and it could really use 4.10's with that large of a tire, at least for performance.

Oh they work, but the engine only does 1700 rpm at 70 and it's lost a lot of it's low end take off power, becuase the larger tires make the gears effectively lower more like 3.42's instead of 3.42's.
