I have an 86 toyota pickup with 35x12.50x15 bfg mud terrains... when i bought it it had 36x15x15 fc 1s. the guy i bought it from said it had 4.11s put in it... it runs 2500 rpms in 5th gear going 60 with the 35s. 4.11s dont seem right to me... does anyone know what it might have? thanks you guys heelp me out alooot!

 

You could have found all of this with some simple searching.

haha yeah i tried searching but my computer keeps freezing... excuses excuses...

 

you need 5.29's

4.10 gears are stock for 28" tires!

 

4.11s for 36"s? And the PO had them put in? Either he is wrong about the ratio, or he got kicked in the head by a mule.

 

Nah, he just lifted it and never touched the gears... far too common

 

i belive it had new gears because you can see the permatic lol also i know he was wrong about the 4.11s bcause this truck pulls the 35s without effort. its also nothing to start out in second gear it dosent even strain dont even have to ease out on the clutch... even with a tired old 22r... i think the guy just didnt know what he was talking about
