I've been slacking on videos lately. Nothing new has come through to film. Installed a Harrop e-locker and 4.88's in the rear of an 80 series today so I shot a video while doing it.

I have a question on the high range under drive setup. I can see the drive gear is smaller so the driven idler gear has to be larger, what about the output shaft gear. Won't it have to be smaller to mate with the larger idler? Looks like this reverses the gear ratio back up to 1 to 1 for all the gears to mate correctly.

The idler stays the same. The driven gear on the output changes. Going together it doesn't look like it'll work but it's magic.
