4.10 gears and 33's

How much did that set you back?

 

$1350.00. Parts and Labor. Check out the link in post #7. It's all there.

 

I ran 35s on a CJ7 with 3.73 gears. It had a stick with no OD. I got 10 mpg city or highway. The engine was so under powered I had to floor it off the line to get moving... then with no OD and 15.5" wide super swampers and aerodynamics like a brick I got 10 mpg highway. A friend with a CJ7 with different 35" mud tires and 4.56 gears got better mileage by 3 mpg. Regearing is your friend. You may not see much improvement on the highway but your overall mileage WILL improve going to 4.11 if you run 33" or larger tires.

 

I have 33's with stock gears and tow a 12ft aluminum trailer with 2 snowmobiles and would love to get some more power back when towing. I had a XJ with 33's and 4.56 gears ARB's and it was a tad over geared but off road it was great. I am going to scour the pull a parts for a 4cyl 4x4

 

Update: I got my true mileage figured out!

For every 10 miles actually traveled my odometer registers 9.2 miles. This was figured by driving on the interstate and checking my miles against the milepost markers.
So, I have a correction factor of about 8.6682%

On my last fill up, I got 16.25 MPG. This was mostly highway miles, but included a little bit of 4X4-ing around in the snow.

On my last woods run, I got 13.5mpg. This was almost all cruising slow in the woods, with a LOT of 4X4 use in the snow, and a little bit of highway time.

At 65mph my rpm's are right around 2100-2150 rpm's.

Hope this helps.

 

So, if I'm reading this thread correctly, and not missing something, the only places to get 4:10s for my '08 Sport/2WD/Auto is either from the dealership or used from someone's 4cyl truck??? I want to reagear this thing once and for all!

 

I don't know much about this topic, but I do know this:

^BUMP^ for anyone who KNOWS this answer.


Im not finding JUST a 4:10 ring and pinion set online

 

It's a Toyota specific gear for our trucks...beyond that your choice is a 4.11

 

I'm interested in 4.10 gears too....where can you find 4.11? That is like nothing of a difference...lol

 

Ok so this is sorta random but I am curious if anyone knows will you be at lower RPM's in 6th gear in a standard instead of in 5th in a automatic for the 2nd gens?

 

The opposite 6th is .85 in stick and 5th is .72 in auto. 15% higher rpm with the stick.

That's why 6speed gets worse mpg.

 

Oh, well shoot, i guess it cost more to have fun. Thanks for the info!

 

Question, if you regear do you do the front and back? and also what brand of gears?

 

Sub and yep, you have to do front and back at the same time if you plan to use 4x4 ever.

 

Thank you

 

East coast gear supply comes highly recomended here. I am about getting close to finally doing my truck. Here in southern California I'm getting quotes around $1500 out the door for front and rear. Just trying to decide if I can justify a locker in the rear but that's a totally different thread. Your best bet is never log back on this site! It gets really expensive.

 

Yeah I can tell lol oh well every hobby i have is fairly expensive anyways

 

All the guy at ECGS did was confuse the piss out of me and frustrate me:

As in this other thread in this section (post #75):

On the freeway a regear will hurt your mileage because you are now at a higher RPM. It is kind of like driving at freeway speeds in 4th gear when you have a 5th.

In the city it will help your mileage because it takes less throttle to get going from every stop. What do you think would happen to your city mileage if you took off from every stop in 3rd gear instead of 1st? You have to give it more throttle to get going. Think about riding a mountain bike, it's easier to take off from a stop in 1st gear as opposed to 18th.

Going to taller tires will always make it look like you get worse mileage if you base it off of the odometer mileage, because you are now traveling farther per rotation that stock so you actually travel more miles than your odometer says.

Also while taller tires actually help mileage (at least in theory) in reality that is not usually the case because when people get new tires not only are they taller but they are usually wider and there for weigh more and have worse aerodynamics. Between this and the odometer being inaccurate there is a common misconception that taller tires hurt fuel mileage, but really if your tires were the same width, tread pattern, and ply rating only one was taller (which would make it a little heavier but not much) you should actually get better fuel mileage, at least on the freeway, and city probably wouldn't be affected much unless there was a huge height difference that would need more throttle to rotate the tires from stop.
