4.56s or 4.88s?

you are not crazy
I heard it was the 3.73(?) use a different carrier but have not gotten any confirmation

 

If your doing a good amount of highway driving then do not bother with 4.88's. You will be reving to high eating a ton of gas. If you are spending most of your time on secondary roads then 4.88's are fine. I went with 4.56's on mine. I have 500lbs of armor and running 265 km2's and the gears are fine for mixed driving

 

I have some nerf bars off my '96 that I would like to re-fab to go on my 2012, but was told it was unwise to weld them to frame. Any thoughts on this....

 

Got my 4.88s installed.Life is good!!Its a little lo with the 265s just as I figured.Cant wait to try with my 285s.Think its going to be a pretty good combo.

 

4lo is probably really nice

 

Yea I tried 4lo.I think I could climb a tree.In 5th on the highway Im at 3000rpm at 70mph.Thats a little busy. Hoping the 285s will calm it down just a bit.No more reving motor or ridding clutch on take off anymore.So I did achieve my goal.

 

285s will be perfect.

 

Just got my truck back, had 4.88's installed. LOVE IT. wish I did it sooner

 

I put one some 255/85-16 km2's also. That come out to a 33" tire.

 

I've always shifted at around 1,500 rpm while in town (0-30mph), yes I do shift a little quick in the 0-30 range but I'm used to it. The truck just feels way more "alive" now. Our top speed limit here is 55mph, I just did 60mph at just a hair over 2,000 rpm. I'll do a 75-80 mph run later tonight and I'll post up the rpm that took for that speed.

 

Ill take a pic of the gauges. When I drive later tonight.

 

Makes sense.

 

Here we go. 2500 rpm at 70 mph.
4.88 gears pushing 255/85-16 km2

 

Just ordered 4.88 gears for my 2.7L

They said 4cyl clamshell fronts will require a 6cyl carrier...due to ring gear thickness.

Also, If anyone does work on their front diff, might checkout the needle bearing replacement from east coast gear supply:

FWIW

 

I run 4.88 on mine with 275-70R17 tires and auto tranny. I am happy with the results.
IMO, if you are auto, go 4.88. Manual, 4.56, depending on tires of course.
Auto will have lower rpms at cruising speed than a manual.

Plug your numbers into the website below to get some good info.

I started a thread a while back that discussed this topic that has some good info.

http://www.tacomaworld.com/forum/2nd-gen-tacomas/352145-4-88-1-4-10-1-why-not.html

And this thread is actually years old. facepalm

 

I just installed 4:56's on my 1996 5 speed 2.7 and I have 265/75/16's, I think that's perfect

 

Not trying to thread jack.. But I'm getting thirds very soon, looking to go to 35s on my 4 banger was going to go with 4.88s but I'm considering 5.29s or would that just be too much?

 

Babytaco runs 35s on 4.88 and I'm pretty sure he likes it

 

I love my 4.88s on my auto with 35s.

 

So has anyone gps checked their truck with 488's at highway speeds? For example the 55-70 range? I'm thinking of going 488 with 255/85r16 but I don't want to wring the trucks neck every time I'm on the freeway
