what gears does my truck have?

i have an 04 4X4 SR5 four cyl and i am just wondering what gears i have in my truck?

'm going to upgrade from my 265/70's to 32x11.5 r15's this summer and just wondering if i will keep enough power to get around fine?

 

THIS CHART IS FOR '95.5-04 MODELS ONLY!
The axle code for your rig can be found on the manufacture's sticker located on the driver's side door jamb as follows:

First digit:

A = 7.5" ring gear
B = 8" ring gear
Next two digits:

01 = 3:42
02 = 3:58
03 = 4:10
04 = 4:56
05 = 3:15
06 = 3:91
07 = 4.30
Last digit:

A = 2 Pinion, Open
B = 4 Pinion, Open
C = 2 Pinion OEM Limited Slip
some '98-00 models have shown a BO code of "???" on the door plate; so far this turns out to be a 3.91 gear ratio, at least for the 5sp. RZN171L-CRPDKAB with factory 31s/265s should be 4.56 with the AT.

 

i found that chart in another thread but i don't have my truck with me now so i was just wondering if someone else knew that had the same truck as mine

 

Manual or automatic?

 

manual

 

Moat likely 4.10

 

if thats what u have then most likely b/c we have the same truck u just have the V6

 

A 2004 3RZ XtraCab 4X4 manual (non-TRD) should have a 3.91 final gear ratio.

 

so if i put 32's on it would i still be ok? as of now my speedometer says i'm going faster than what i really am with the 265/70's on. It has to be around 69 on the speedo for me to be actually going 65

 

32's should just about perfectly correct your speedo. And yes, I have 4.10's

 

i was debating going with 33x10.5's but i figure that would kill my power and mileage so i'm going with the 32's

 

I understand the lower the ratio the better the fuel economy; the higher the ratio the better for towing (or something similar). What do the other two gears do? I have a code B03A (2001 V-6 TRD 5spd).
