i have a toyota pick up im straight axleing puttin chromollys front and rear. It has a 327 motor 350 turbo transmission and toyota transfer case. I bought a transfer doubler kit the 4.70 transfer case gears 529 rearend gears and i plan to run 38 to 44 inch tires now im bein told that id be geared way to low so i was wondering your alls opinions and what u all think i should do and or what combo i should run? thanks for any opinions thanks David

I'm running stock 4 cylinder with dual cases with 2.28 in each case with 5.29 gears running 39.5 tires and love my gearing, having a lower gear in 1 of the cases would be even better selection of gearing. With you having double the power I really can't see where you can go wrong with the gearing. Just my opinion...

Assume on 40s, it won't see much if any street time?

If all you're doing is crawling, no street, no mud, then yeah, I think its hard to have too much gear...

Keep in mind that the 327 should have at least twice the torque of the stock 22R so you really can't compare the gearing of other Toyota rigs with the 4 banger. I've wheeled quite a bit with several Toyotas setup with various gears and such including one guy that had a stockish 350 that originally had the stock 'yota 5 speed and t-case with 4.10 gears and 34" tires. When he went to the 350 it made a world of difference in how the thing could crawl and lug as he doubled the torque output to the tires (about the same as the difference between high range and low range when you look at total torque output). He eventually swapped to a TH350, NP205 (less gearing than stock t-case), and 4.88 axle gears with 38's. It wasn't setup for hardcore rockcrawling but for typical midwest trailrides it had decent crawling ability.

I think the combination of the doubler with one case at 4.7 and the 5.29 axle gears gives you a low-low range that is not really practical/needed for anything considering you have a V-8 and auto. That puts you over 140:1 not even taking into account the torque converter multiplication (there is some debate over this but it should at least double the gearing at certain times, so that puts you at almost 300:1 effective gearing).

Assuming you are keeping the Toyota axles, so good luck keeping them together with the V-8, 44" tires, and ultra-low gearing.

Good point. I was just thinking about drivability, but you'll have to consider longevity too..

when i bought this stuff i had a truck with 4 cylinder and all stock and my plans was to fix it up but i had the one with the v8 and the frame broke on it so i decided to it since im 4 linking the rear so was just wondering peoples opinions on what direction to go. im thinking maybe the 4.7 with single case and stock 410 gears and see how that works for me
