overdrive survivability?

[Tim Smith]

Tim,

Thanks for the info. I already have the TLC axles and the rear is a 1 ton so I figure I might as well put them to good use. Also, where I drive, there are 3 seasons. Winter, mud and black fly season. The back roads are all made of sand and quickly turn to quicksand in the spring thaw. Dual lockers will be perfect for 2 out of 3 seasons.

No problem. Just trying to pass on what little information I have to give.

As for the Fairey, I used to have one in a 109. Although noisy toward the end, it never failed us. It maybe didn't get all of the oil changes as it's schedule would have liked but that truck did do a lot of sitting. It was a stock 2.25 so can't tell you about more power being an issue.

I've got a Roverdrive in the 88 and it seems more robust. It's less noisy but tends to run hot on extended highway runs and is a bit clunky to engage. When I picked up that truck it had a suped up 2.5 that the previous owner claimed had an output of about 100hp or so. It was fast but the motor needed replacing before the Roverdrive did. Still running the Roverdrive to this day.

Cheers!
