Any of you gone to 4:30 gears?

That’s what I meant.

 

4:88’s here . I went 4:88’s before my suspension and wheels. Fixed everything up just fine ! When I put suspension under it and the Nitto 295/70/17’s on, its still perfecto !!!! I put the ARB locker up front at the same time....cuz I wanted to lol

 

Hmmmm I think you can put want WTB???

 

3.909:1
Front: 41201-79465
Rear: 41201-79525

4.300:1
Front: 41201-79485
Rear: 41201-79535

I looked up the 41201-79535 and it says it is for a manual trans truck . Does it fit the Auto trans truck also ?

 

Thank you Sir!

 

If the auto truck has a locker, yes. If not, no.

Jeff

 

I think the front 3rd member will be the same, but I think the rear would be different. I think I have seen 4.56 before. Look at ECGS.

 

Wait till you reach 3-4000 miles. Just drive it . It will wake up . Go for a long drive

 

interesting, 15-16 is the best i can do on 33s and stock AT. I did recent trip and barely averaged 17mpg driving 70-75 on highway(1800 miles round trip). Truck would always down shift and hold a gear a lot longer than it needs to. I just got the OV tune so I hope to squeeze a little more

 

Is your speedo calibrated with a Hypertech? If not, then your calculations are going to be off.

I have a Hypertech and have it calibrated damn near 100%.

Before gears I was at 17-18mpg, so it's been a slight improvement.

 

So just to be sure, the MT Sport (4x4) also has 4.30's with the 8.75 rear correct?

 

If it is a 3.5L V6 manual it will have the 8.75” in a 4.30:1 ratio.

TRD off road and pro have the 8.75” locking differential reguardless of transmission type. Basically If it is a 3rd gen with a locker it is the 8.75” ring gear differential.

TRD sport and all other MANUAL TRANSMISSION models available have the 8.75” differential but are open carriers.

If it is a 2.7L I4 manual it will have the 8.75” in a 3.90:1 ratio.

 

Yep 3.5L, thanks man. Looking at ARB lockers.

 

Which are the correct oem part number for 4.30 gears with e locker for a 2017 Toyota Tacoma trd pro automatic transmission, I seen two rear parts number
Rear: 41201-79535 or Rear: 41201-79525
Just want to make sure I order the right ones?

 

25 is for the 3.9, 35 is for 4.3.

 

Is the part number: 41201-79535 with locker or without locker?

 

The ring gears don't care if it's a locker housing or open housing.

Are you 4wd? If so, are you also changing the front diff gearing?

 

Thank you @BabyBilly. Yes im changing both front and rear, just wanted to confirm the right part number for the rear because I saw on a different thread, post #45 by @Jeff Lange that part number 41201-79535 is without locker

 

Well I'd trust Jeff more than me. Maybe you should seek clarification.
