I have a 79 35ft Bird w/3208 NA and a Richmond rearend does anyone know if there is a 2 speed gear replacement for this housing? Or do I need to get a Eaton set-up.
Thanks
Carl

I have only seen one really successful conversion to a two speed and this was using an air shift rear axle from a wrecked dump truck.The axle was an Eaton. The best way to use it with the allison four speed was to wait until the allison shifted into the highest gear then shift up the two speed. it increased milage somewhat, and added to top speed. it was shifted down before the automatic began shifting down and was shifted to low for descending hills. shifting was done by an air control lever.

We purchased an 82FC in '04. It has a 2 spd axle. The previous owner said they used Goody's in Toledo,OH to build it up. They said it came in backing plate to backing plate. I think they sent the rear-end up to be redone.
We do like it tho. Noticibly better road speed on the level, but you will sacrifice some power on the hills. On the lo side, 57mph is about it, but for travelling the backcountry or in town it has it's benefits.
This is more of an observation than a how to, but real glad they did it.
