4.88 Gears in a 2.7?

Hello everyone I’m new to the community and wanted to hear some of your guys feedback about regearing. I have a 2010 ACLB Tacoma with the 2.7 and a 5 speed. I was looking to regear to 4.88s and get the 3rd member and clamshell from east coast gear supply. Any thought/recommendations? Please let me know!

 

I'm assuming you currently have 4.10 factory gears and wanting 4.88s to run 33" tires?
Not sure if you plan on DIY but imho, regearing is left up to shops which usually include some type of warranty. Not an easy task but you also have to do both axles for the home mechanic. I also wouldn't buy the parts and have a local shop install because if something goes wrong, they can blame it on the supplied parts. Although you pay more if the shop uses their parts, at least any parts related issues including labor is covered.
Welcome to TW.

 

I just did my prerunner 4cyl which went to 4.10 to 4.88 with and arb locker on 33s. If you get the complete 3rd member it is pretty much drop and play. I talked to Paul at ECGS he was very helpful, but the only issue I had was they suggested the Harmonic flange for the yoke which is too small to fit the yoke to the driveshaft so I had to reuse my old yoke. The only other problem was the pinion seal was broken. I cannot say for certain if it came from ECGS that way or if the yoke pinch the seal and tore part of it.

 

Interested in buying anyone's old 4.10 gear set if 4x4

Kflo on youtube has a video swapping in whole assemblies with higher gears that a shop put in them, requiring shipping back of the core parts.
At a higher cost than just buying the gears and installing yourself.
Which takes special tools and knowledge. Like the yellow paint test on the rear diff gear.
Many youtube videos out there on the subject.
Definitely more specialized than replacing an engine air filter.

There's pros and cons to that.
Cons: if you have a lot of money and want it done right now, a good shop can do it right now. DIY cannot. DIY would probably require at least a week of learning/watching videos to feel confident (wastes time)
Depends on if you have big tires first or not. They say to regear first, not tires first.
Even if you went tires first and no regear (less mpg, less power), that still costs less than a regear

Probably a good time to think if you want to do anything else at the same time, such as lockers.

Pros: cheaper to DIY
even if buying tools, still probably cheaper
-get to keep those useful tools for life, or re-sell them
-better able to understand, diagnose, and repair the truck if it ever has issues in the future, after learning how to work on it

figuring out which gearset is best will be a challenge
there are maps that show what the RPM is at, per gear
Toyota probably has a repair manual spec sheet of your particular transmission and what each gear in it is sized, which will correspond to certain RPM and speed based on final drive ratio and tire size
I imagine everybody eventually wants 35's because:
-can fit
-more ground clearance
-looks better, fills fender more
-off road truck usually = bigger tires
-when tires eventually wear out, people want to try bigger, not repeat same thing

 

I've got the same truck, regeared to 4.56's on 33's. They do great but I would go 4.88's if I was to do it again. Especially with the added weight of the bumper and other armor. ECGS is awesome, I would highly recommend going through them for yours. Rear diff takes maybe an hour to swap, front takes maybe 3-4 depending on your pace. Both are easy to do. Add a locker while you're having them done.

 

I wanted to go with 4.88s and run 315/75/16’s with armors don’t know if that’s gonna be enough. I’ve talked to a lot of people including eccs about it and they said that would be the ideal gear size for me especially since I’m daily driving my truck. Let me know what you guys think
