4Runner on 33x10.5, Gear Options?
I have a 95 4Runner with an auto tranny on 33x10.5 Mt's. I'm thinking about putting new gears in. Will they make much of a difference, is it worth the money? Whats the best set to go with, 4.88's, 5.29's or 5.71's?

I have a 5spd SR5 (31" stock.) which means I had 4.56 gears. I put a 285/60/18 (about 33") and it felt like a dog. I changed to 4.88s and it felt much better.
I would say that YES, you will notice a huge difference.
You dont' say if you have a 5spd or auto, the auto's came with 4.88s and you'd want to step to 5.13s

You may want to look at the axle code and see if it came with 4.88's if so you wont gain much by going to a 5.29 but if your 4.10 or 4.56 then you will see a difference. Its worth mentioning that with 5.29's and 33's your speedo will be off by a considerable percentage but you will be plenty happy with the performance especially in the hill climbing area. If indeed you have 4.88's then you cannot go to any ratio with out changing complete thirds as the factory 4.88 thirds cannot accept any other brand or style of gear other than the OEM 4.88's.
edit.. looking at your sig I would say if your not running 4.88's then you should definitely put in some 5.29's to help that poor critter out lugging around all that accessory weight. I know my 90 xcab with bumpers,sliders,dual cases and a winch tips the scale at over 5k so Im sure you runner is at or beyond that.

Also the automatics have very high top gear so you would still be able to cruise all day on the hwy.
But I was thinking. If his ride came stock with 31" tires and 4.88gears wouldnt going from that to 33" tires and 5.29gears put the speedo pretty close?

Great info! With my current gears and 33's my speedo is off about 10%. When it says 50, I'm actually going 55. Where is the axle code? I looked on the axle and didn't see it.

It's the G144, "A" stands for axle and "TM" stands for transmission. And yes that is the 4.88 gears. Go with 5.71s if you want lots of power, go with 5.29s if you want it like the stock dog...

G144 = 4.88

Those who said going from 4.88 to 5.29 (or any other one step change) haven't done it. Going from 4.56 to 4.88 made a HUGE difference in my truck.
Three things:
Your 4.88 diffs are not regearable. You're gonna have to buy entire third members (would be a good time to do an elocker!)
IMHO, the autos are undergeared from the factory (31 + 4.88). I would go 5.71 for 33's so you can actually use the overdrive.
You can't use a calculator to see how much the speedo will be off. That has to assume that the speedo was accurate from the factory, and in my experience, that isn't true.

You can do a 5 speed swap and keep your original 4.88 gears. You would be geared perfect for 33s then. Depending on what gears you get and who you have install them, ud be running about the same price as the swap.
Just an option...

Was this one step change on a manual or auto trans.? I'm just wondering if the type of trans. would determine how much of a change it would make.
