It's because I like cruising at 120+ on the Interstates or when up north in Alberta... The tall 3.70s, with the 255 85R16s make for some good top speed. Corrected speedo: 2050 RPM at 100Kph and if I don't drive it like it's stolen, I can squeak 32 MPG (Imp) out of it.
...and that's why!

So thats what I'm doing wrong, lol! My BJ74 with 4.56's and 35" rubber is running at 3000RPM at 120kmh and only getting about 19mpg
As much as I would like to get the toybox right now the availability, mods to install, down time and price by the time its all said and done are holding me back. I think the advance adapters 4:1 is definitely the next best option for me at the moment as my t-case is due for an overhaul now. I'm thinking if in the future I ever wanted to I could still add the toybox with the 2.28:1 gear set and end up with the same final crawl ratio.
Do you think the 10% reduction in high range with my 4.56:1's and stock 13BT would be enough to run 37's ??
