hi guys, i just recently purchased my fist toyota truck. its a 1990 toyota pick up with a 3.0 v6. the problem that i have is that my gear ratios are off. its been lifted and has 33s on it. i researched and i believe 4.56 gears ratios is the way to go. i saw these on ebay TOYOTA PICKUP V6 8" 4.56 RING AND PINION YUKON GEAR and was wondering if they were any good. thanxs

Yukon makes damn good gears, I would maybe consider 4.88s though.

I have Yukons in my front diff. So far so good. I have a 5 speed, and running 31's with 4.56's.

stryker30

my mistake, i have 31s. the problem that ive encountered is that on the freeway 3rd gear is good i switch to 4rth and i feel like im loosing power and 5 gear is a joke i never use it. its a 2wd. know what would be the power diff between 4.56 and 4.88.

2wd, its lifted with 31's? What was the stock gearing and tire size?

stryker30

it came equiped with p215/65r15 the only thing else it says on the side door sticker is c/tr 179/gp1 and a/tm g382
r150

I have not dove too far into 2wd gears and tire combos. I have no clue off the top of my head what will work for your rig. And my head is too fried to start researching tonight. Sorry dude, hope you find a little more info.

Look up that g382 code to find your gear ratio.

hey man i have a 2wd 2rz 4cyl with 33s i run 488 and 5th gear at 75-80 is as fast as i can go without winding it out i Cruz at 70-75 tho and nothing slows me down i rarely have to down unless i am going up huge grade and my truck is heavy with full cage 2 spare tires 44 gal fuel cell on Bord jack tools...
so i would sugest 456 for 31s and no exta waight

G382 is g= 8 inch 38=3.417 gear ratio 2= 2 pinion.


The gear calculator (grimmjeeper) doesn't have an application for 2wd, so I am dead ended for now. Not sure how that ratio/ tire size equates up to 31's.

nice thanxs alot i do ride dirtbikes a lot and load them on my truck but i think 456 would still be good
so those ebay gears should do the trick?

ibeamtaco

yeah Yukon is a really good brand

hey guys i know its been a while but i finally ordered my gears, what else am i going to need. am i going to have to buy a gear installation kit for my new gear ratios or is it going to be more like open up the rear differential and instal the new gears,, if u guys have advice id appreciate it thanks.

If you have never done gears, I would recommend taking them to a reputable shop to have them installed. Especially Toyota gears.

stryker30

ive done work before on my truck im just trying to figure out if theres anythng else i might need to do since itll be my first time taking apart the differential to instal gears

Hi Stryker-
The 4x4 trucks with 31" tires run 410 or 456 gears all the time...so I think 456 would be my choice, too. It sure will seem to have a ton of get up and go off the line I bet. No prob pulling any kind of load also. I'm on my summer fishing break so all I can do is point you to my website....I have a couple of pics of gears and such

just because you can turn a wrench doesnt mean that you can set gears... you'll want to have a shop set the gears, or watch CL for a 4.56 3rd (assuming you really do have a 8" housing) and find one that came with those gears from the factory. i was able to get my 4.56 rear 3rd for a 100 bucks.
