5.71 gears!
 

Total noob question.. but what's an estimated price range for droppin 5.71 gears in an '85 3.slow 4runner 4x4? ... or how hard is it to install gears yourself?

did u swap a 3.0?

nah P.O. did for who knows what reason.. cant afford a swap for a good while so i thought id make the best of it..re gearing would do me a lot of good.. any takers for my original question?

5.71 are supposed to be a little weak because of how small the pinion is so if you are doing any off roading you may wanna just go with 5.29's As far as the install I'm not sure though you can buy complete thirds set up with new gears from trail-gear, marlin crawler, or allpro. If your not pretty comfortable with mechanics and tools and such I wouldn't suggest doing them yourself.

Just my .02

thanks for all the info so far.. :bump:

Check out marlin, or allpro.

OR

Randys ring and pinion

Those will be the price for the gears.

Call your local shops to verify for the install prices, because it varies

for front--->http://www.ringpinion.com/ProductDet...px?ProdID=1124

also.. 5.29's are good to have with a 10" lift and 37" tires right?

:bump:

you said 85 4runner? the ring and pinion you showed was for an IFS front, isn't yours strait axle? if it is strait it will be an 8" ring gear.
I have done gears but only with my dad who has been doing them for twenty years. i would not recomend a gear install yourself unless you have some one to show you/ coach you through it. it is a good skill to learn though!

but if you are still interested in doin it yourself i think that randys ring and pinion sells a how to video but its really not that hard if you have access to a press
good luck

i assume it only has the factory t-case. i run 4.88s in mine but i have two cases. i think you'd be fine with 5.29s and the 3.0.

you need 2 of these

you also need 2 setup kits for an 8" 4cyl. diff

There is nothing wrong with 5.71 gears. I run them on my 88 4runner (85 front axle). The key is making sure they are setup correctly. Most people I know uses ZUK (gearinstalls.com) cause he's the Toyota diff guy. You can get the cryo'd 5.71 gears from him also. If you are looking for this to be done ASAP, then ZUK won't be your guy. He closes up shop in the summer (too hot). Probably won't be open again until October. Just make sure whomever you use, really knows what they are doing if you go with 5.71's.

Good posting^

The bigger the R&P the more important a good install is.
