Hey all,
I'm only really looking for people with personal experience with 34/35/36 inch tires who have opted to do low range T case gearing. I'm looking for some "buttometer" type anecdotes.
I'm setting up my H55F/cable locked BJ74 as an all around daily drivable adventure rig that needs to be a competent highway machine. I'm building it to be as moderate and bulletproof as possible with some smart drivetrain mods, as much armor as needed, and the right sized tires that'll get me where I need to go in style and class. The end goal is 35" tires, low t case gears, bumpers/sliders/ with a roof rack and RTT. It'll mostly be used for family friendly adventures, but a couple of times a year I want to be able to tackle some Rubicons, Moabs, etc without worrying about blowing things up. I like low gearing and I like rigs that idle up things.
I have Nitro Chromoly axle shafts and was planning on running the factory gears, relying on T case gears. After talking to Kurt from Cruiser Outfitters, he said I should at least consider 3.3:1 gears with factory high range. My plan has been 4:1 gears with a 10% under drive.
So here's the question: anyone done the 3.3:1 gears with 35" tires and a 13BT? I know people have 4:1 gears with under drive, but looking for your opinions too. I am not planning on juicing my 13BT beyond possibly adding a small intercooler and shimming the waste gate for a couple of extra pounds of boosty deliciousness. As it is it's on 33s and it does everything I ask and gets 20-22 mpg which is where I want to be. It's slow without being too slow, which is fine with me. The 13BT is fine power wise, but does not have the freight train-like terrain consuming lumpiness of the 4BT powered cruiser or the miraculously stable low RPM performance of 1HZ powered Cruisers I have owned, which is why I lean toward 4:1 low range gears. Thoughts?
