Would one of those gear vendor overdrives work on a bigger truck as well? I have a 2 ton, looking to rebuild my brown and lipe overdrive. So your subject caught my interest, comparing pros and cons. My truck has the sm420 4 speed to, found that out on this sight to. Also I have the 2 speed rearend, vacum type. My truck weighs 6,000 lbs.
I can run 52 mph on flat ground at 2,800rpm with the brown and lipe overdrive, wonder what the gear vendor unit would do? and would it be tuff enough to handle weight of the truck? I only haul light stuff - model T or motorcycles. Appreciate your thoughts, thanks Tom.
