I had 2 of these piggies. Only owned the back one for a little while.
Front 1 Alcan 4" lift 35x12.50, back one Man-A-Fre 4" safari Kit 33x12.50
Since I'm getting older, I don't remember distinctly, but I do recall they both rode a little rough, with the exception of a load of 300ish pounds in the rear of the front Pig with Alcans rode MUCH better. It also flexxed much better.
I wheeled the crap out of that front FJ55 with a 2F, 4spd, 4.10's and ARB lockers front and rear. It went more places than I wanted to go without major damage....minus that last trip out... In the mountain passes of colorado I for sure wanted more gearing and power/low range but I still did everything. You already have power steering, I needed it badly for wheeling, but it worked without.
Personally I'd go an OME lift, decent shocks, 255/85r16 Yokohama's and a rear locker and go everywhere. If you have a built ready to get 4spd/tcase setup, slap that in and call it good.
Spend the rest of your money on Bacon Scented Air Fresheners...mmm pig! Amazon product
Yes, same final ratio. The 3 speed, like an SM420 or SM465 with no granny gear, makes your engine and driving style cater to a much wider RPM range as you have to lug it lower at the engagement and wind it out higher before up shifting.
Having an underdrive gear helps to offset the shortcomings of a 3 spd, mostly in the dirt. Unfortunately, Toyota’s drivetrain engineers must have been staunch supporters of “momentum wheeling”.
And to expand on where I was going with that last reply, the final low-low ratio with the later 4spd trans and t-case in ~28:1. As anemic as that is, the 3 spd setup is even worse, at like 26:1 (IIRC), despite the t-case having the lower 2.3:1 low range gear set.
