from what i can figure my 88 4runner has 4.30 gears what happens if i put axles in it with 3.07 gears / ie benefits draw backs, how much will that effect my on/offroad performance or lack of any help appreciated thanks

Why do you want to put the axles in, anyway? What's wrong with what you have?

headhunter

not enough flex

Jay351

3.07 gears would be fine.. if you have a massive v8.

If you are in the 30" range of tires you want at least a 4.30 gear or higher.

headhunter

but the ? is what will it do, ie higher rpm all the way around, lower rpm, like what will it do
oh yeah thook its stock with 31's (ifs the whole kabootle

headhunter

id like to stay with the ifs but the flex is the problem. i was thinkin about building new axles with u-joints instead of the cv ones because the inner joint is the limitation for flex in the ifs. basically the same as a square drive shaft except shorter of course. and the t100 axle and longer control arms is not the answer. ends up too high

I fail to see how an axle with different gears will improve flex.

If you want more flex you need a better suspension or cut the IFS off and SAS.

Like saying a new shifter knob will affect how cold your AC blows.

well the gear ratio wont do anything for flex, i just picked up a set of axles(free) they have 3.07 gears, im trying to figure out what happens if i put the axles in the way they are.

Jay351

if you put that ratio of gears in you will have a hard time driving the truck.

sure at hwy speeds your rpms will be MUCH lower BUT you will not have the power to get up to any speed.

for that size gear you would need a 24" tire or so.

your truck will not want to move. It will be an absolute dog. If you are going to use the axles you picked up for free they will nbeed to be regeared

HuskyRunner

Umm...I may be missing something, but the axles don't determine the gear ratio, the differential does...

881stGenRunner

okay then the differential gears are 3.07. think people

headhunter

ok how about differential housing, rear drum to drum, front rotor to rotor.

headhunter

the thing is im on a very tight budget, fab is not a problem, parts are, so free is free, if i cant make it then my friend can, nad from what i've seen gears are expensive. 2wd not so bad but 2 sets

HuskyRunner

With 3.07 gears, you're engine will have a heck of a time turning your tires. That will kill your gas mileage, and hurt your performance offroad, because the engine will not be able to stay in the powerband - it simply will not have the power, especially going over obstacles and up hills offroad, which is obviously the goal, since you are looking for more flex out of your suspension.

exactly how well does a locker work? will it make a drastic difference in my stock 88 4runner off road, and i dont think i'd like a spool which as far as i've seen its the cheapest other then a lincoln locker.
