So i have a 4.3 swap taking place in my 87 4 runner which currently has a 22r with 33'' tires. I just put 4.88 gears in it hoping the would do the trick. It helped, just not enough. So my question is would you leave the 4.88 in it with the 4.3 and a 700r4, or swap the 4.10 back in. The 4.10 are still in the carriers,i used differnt carries for the 4.88, so it would be easy to switch back. My thinking is i could sell the 4.88 and carriers to cover some of the cost of the swap. The truck is a daily driver/ mild offroading, camping truck
Just looking for some opinions before i tear the truck down.


Thanks, Doug

 

cant speak from experience but i would bet 4.88s will be a little tall... try it if it doesnt work throw the 4.10s back in.

 

My buddy just swapped 4.10's into his SAS'd S10 ZR2 on 35's that just happens to have a 4.3...

 

Yeah x3, 4.10s will be the best for what you use it for.

Im planning on 4.10s with 33s and my stock tranny when i do the swap.

 

jack, your going to need a new transmission... so will the OP... i dont think they make a bellhousing adapter for the transmission your currently have.

And the op is using a chevy tranny.

 

Well that was fast, thanks guys for the replys. So looks like my next post will be in the classified section.

Thanks, Doug

 

I am running 4.30's with 33's and the 4.3/700r4 swap and I like the combo... the 700r4 has a 21% lower 1st gear so it comes of the line good and I run 2200 rpm at 68-70 mph.

I can't see going much lower ...maybe 4.56's ...because it seldom needs to kickdown from overdrive.
if you lived in the mountains where the kickdown was a constant problem 4.88's would be nice!

 

im running a 4.3 700r4 with a 208 transfercase and running 35s while running on the street the od is great and when in the woods 4low i can take my foot aff the gas and the motor will still pull the 4 runner without any strain makes life great in the woods.

 

since your 4.88's are in already finish your swap and if the gears are too deep you can switch them after. Do you plan on ever going to a bigger tire?
I currently run 4.56's with 33's and am finishing my 4.3 cpi swap this weekend hopefully. I plan on stepping up to 35's and have a pair of carriers with 4.10's if my 4.56's are too steep ill switch them out. but im betting 4.56's with 35's will be a good match. your 4.88's will be a little tall for the street but off road will be nice especially when crawling and if you dont have a doubler or lower t-case gears

 

What gears for better hwy speeds.4.3 with th350 ob 410 gears and 31inch tires

 

i run 4.88s and 35 mud terrain runs fine,will cruise at 75 to 80 if you don't watch it

 

i run 4.3cpi to r150 and run 513 gears but I'm on 37s and it tops out at 95mph
