Save money by switching 4:10 to 3:73?

Hello,

Have an 09 Tacoma access cab 2.7 4bannger 5 speed. I find the fuel economy to be somewhat lackluster. I was wondering if anyone has played around with switching gear ratios from 4:10 (stock I think) to 3:73 to improve fuel economy. Do you recover the cost of switching the gears from savings in gas?

Cheer,

...Putting on normal wheels and removing the lift will save you more gas than regearing...

*shakes head, walks away*

 

The 5 lug has a different ratio from the prerunner & 4wd. I believe you have 3.15:1

 

Let's say re-gearing saved you 5% in fuel economy. This would be a saving of ~70 cents per hundred km according to my numbers, so it would take very close to 300,000km (~180k miles) to recover the cost of re-gearing assuming a $2000 job. Hard to see how it'd be worth it.

I saved 15% by switching to Geico...

 

Is your truck 4x4, is it the avatar pic?

 

Whoa...that truck is from Canada? Do those tires allow for you to float across the frozen tundra?

 

HAHAH no that's not my truck in my display picture. I wish it was tho.

My truck is completely stock.

 

Not my truck hahaha. I'm a bit more rational with my investments.

 

Wouldn't you want to go the other way. Like 4.88?

 

your numbers seem to add up. I didn't think switching the gears around would cost around $2000. I thought that all you needed to do was pop the covers of and change the ring and pinion gears in both the differentials?

 

Hahah nah that's just silly

 

I don'tknow about yyou but with my 4 cylinder with with larger tires benefitted from 4.88 vs going smaller.

 

Pop the covers off and drop in new ring and pinion is a gross generalization of the process. It's time consuming and fussy for a first timer. You have to get your gears set up right for them to work properly and last.

 

Curious what gas mileage are you getting now?
