[sonofmayhem]

i wanna get new gears for my 85 4x4 sr5 22re efi 30in and 33 in and in between tires. any suggestions

[black93DX]

4.10's should be fine all the way up to 33's. Go 4.56 or 4.88 after that.

thanks does anyone know where i can get 4.10s for my 85 4x4 std cab 5spd and ?should i put them in front too?

[ElmerFudd]

Don't they come 4.10? Correct me if I'm wrong.

Listen to ElmerFudd and look for some 4.88's if going to 33".

[snowboarder2359]

4:88's

thanks guys with out all this help id be broke! so are gears easy to do yourself, do you need a lift or can i do it w/ some jack stands?

[texas12]

Not a DIY project for most people. There is very critical run-out specs when installing the gears.

[sonofmayhem]

could i throw in some 4.88s or 4.56s, and keep the 30s and expect trouble?

The manual trucks come with 4.10 or 4.11 same difference most auto come with 4.30. Both axles must match or the tires will spin at different speeds and lead to damage. I would go with 4.56 if you are planning on running different sizes of tires. If you are only going to run 33 go with 4.88. Running that ratio with smaller tires is going to put highway rpms very high.

I must insist that 4.10 gearing is ONLY good for up to LT235/15 tires!!!!! That is roughly 28" tall. 30x9.5 is bearable to an extent. 32" is f'ng MISERABLE!!!!

The government has been all over manufacturers for decades. If TOYOTA took the logic of "up to 33" is OK", they would have installed 3.90's or "worse" right from the factory to increase MPG. The 1980 4x4 models run 3.90...this only lasted one year if memory serves...for good reson: it sucked!

Gears and tires are hand in glove. They must match.
