Thats a different project than we see here usually!




just curious Issaam, do those big rigs still run an Eaton/Fuller trans?


We run the air lockers, (also not sure who makes em) but they are the cat's meow. I have a few regular spots where I need the air lockers to get into and out of certain calls...on dry pavement.
On the flip side in the snow if you're on a bit of a sidehill (it doesn't take much) and the rears are locked the truck will slide sideways very easily. It's nice to be able to turn off the air lockers and re-gain lateral stability. Mostly in the snow I just run the interlock and keep the diff's "open".
Selectable FTW on a big truck...and I'm a Detroit Locker fan normally.
The truck?Specs iceman?
one more vote for selectable. it's been several years since I've driven truck, but back in the day I've used both. selectable is the shizznit when you need it.We run the air lockers, (also not sure who makes em) but they are the cat's meow.

If things work out for me, I will never drive in the snow again, this year I took off from new years until now, last year I chained up once.one more vote for selectable. it's been several years since I've driven truck, but back in the day I've used both. selectable is the shizznit when you need it.
auto chains are pretty sweet too if you spend much time in the rockies.
Well underpowered no, you always have lower gear, at full load going up Donner on I80 I run 25MPH on the steep sections, would I like to go faster? yes, but it works out for me.Wow im impressed with the mileage! Do you ever feel underpowered or wish you had more than a 10?


Exact same drive train I am running. Sweet spot seems to be at 65 mph. It needs another gear between 8 and 9 when I hit a grade. Just does not want to pull in 9 and 8 spins high rpm's.
