diff gears

[bushwalker]

just wanting to see about 75's running diff gears what ratio/ tyre size combo, also what brand to go with, i have a hzj 75 trayback got 35x12.5x16 on and wanna get some economy and driveability back

I tought overthere 75 come with 4.11 ( almost here ) but if you wanna get back to the close factory gearing .. change 'em for a 4.56 set ..

If you like more hardcore wheeling 4.88 you choice . .

I have been looking at doing this as well. I have a HJ60 with 35" tyres and the gearing just isn't right, especially as I want to tow a bit with it too. I have looked into changing the Crown Wheel and Pinions, but have pretty much decided to go with Gearmaster transfer case gears. They lower the low ratio by 55% and the hign ratio by 8%. That pretty much equals a diff ratio of 4.44 and then you get the added benefit of the lower low range as well. Snake do these for approximately $1500. Old Mate Tapage runs them on his rig - Hi David.

Hi Dude ..

I thought ( in my case Marks underdrive t-case gears ) those gears are best ever upgrade .. you get HI range reduction at time get Low gear reduction ..

Are a little noisi .. but tha's fine to me .. anycase I'm always earing my turbo sound

I have 4.56 and those gear set with 37" and I'm a little short in HW can go over 120 km/h and it's just on the limit .. usually fine 100km/h @ 2500 rpm
