Help help how can i gear it down

i have an 08 tacoma 4x4 and im putting 305 70 16 dick cepek mud countrys on it i know i need to gear it down because ive only got a 2.7 but im wondering if i can go ahead and buy a lower gear set that has the electric locker option and put the locker on a month or so down the road and what ratio should i gear it i dont really care about speed i only live around 2lane roads with a 55 speed limit

 

What kind of lift do you have under that??

I don't think you'll find an electronic locker....ARB Air Locker or a Detriot TruTrak...but that's about it I think.

Not sure what ratio to tell you to go to...but the tire calculator on the site (in the menu bar in the Wheels and Tires forum) is pretty helpful...

 

i have the revtec 3 in

 

with what lift?
gearing should be fine for moderate off-roading.

 

i just thinkit will make me a lot weaker on take off figured gearin it a little lower would help

 

so the larger the gear ratio the lower the gearing is right?

 

Thats correct. The Higher numerically the lower the gearing. You most likely have 4.10 gears, I would stick with those.

What is your stock tire?

 

it came stock with 245 but im runnin 265 75 bfgs right now remember i have 2.7 4 cyl

 

245 what? I'll need all three numbers. How about give me the stock size ???/??/?? then the tires you are running now, and the size you will run in the future.

 

you can gear it down to 4.56 and be close to stock power to the ground. But with the added weight youll get less mileage and less acceleration

 

stock was 245 75 16 now is 265 75 16 and later 305 70 16

 

he said stock 245s...245/75-16= 30.5"x 9.5" x 16"
now he has 265/75-16s= 32"x 10.5"x16"
He wants 305/70-26= 33"x12" x16"

If you go with a narrower tire like 255/85-16 you get a 33" tire thats 10" wide= alot less trimming. Also, 12" wide tires require 9" wide rims.

 

do you think 4.88 would be to much i just do want to have to wind the crap out of it i dont really care it it top out at 75 lol

 

im gettin xd series wheels to gona put an offset not real sure how much trimming but dont think it will be to rediculous just have to try i sure do appreciate yall helpin me out

 

Ok so your stock tire was 30.4" tall and your gear was 4.10
On your truck now is a 31.6" tall tire and your gear is 3.94
You want a 32.8" tall tire, your gear will be 3.80

I have some 33" tall tires with stock 3.73 gears. Seeing as my tires are taller than stock I have less gear than that something like 3.50 or so I'm guessing becasuse I don't want to do the math. I think your stock gears should be ok. Thats my $.02

Oh and I think the 305's would be too wide, and heavy.

 

but your truck has the 4.0 v6 i have 2.7 4cyl

 

Oh yeah but don't count that little guy out. I wheel with jeeps that are making the same if not less hp and tq than you and they are doing just fine for the avid wheeler. These are also daily driven vehicles. I've been drinking and can't recall the specifics right now which is why I asked you to post your tire sizes completely, because its a jumble right now. Back to my point though, I believe you are making enough torque to not have issues with your take offs. You'll notice it but I don't think it'll be that bad, I certainly don't think it will cost you any mpg. With the exceptions of the weight of the tires. I would look for something skinnier. Just my opinion, I would also think there would be a bit of rubbing on your UCAs with those tires. You can play with the back spacing but only so much.

 

buddy i sure do hope your right lol thanks for helpin me out im gona get my wheels and tires and get the trimming and spacing lined out and hope i dont need it thanks for helpin me out merry christmas

 

with 33" tires 4.11 (stock) would work but give you no power. 4.56 would give you the equivelant power of stock gearing with stock tire. 4.88 will give increased power but kill highway driving as you will winde it out while cruising...like driving in 4th gear at 65 mph

 

4.56s will be the way to go. If your really looking for some extra gear you could go with the 88s. You need to keep in mind that your tire isn't just tall it is wide which causes two things, one being rolling resistance and the other being weight, and lots of it. With the lack of power the 2.7 puts out, you would be foolish to not go with at least a 4.56.
