I believe we know that TT rear ends were offered in 2 ratios, 7.25:1 and 5.0625:1. I also believe we know that a Ruckstell, using either gear ratio set, offers a direct drive and an under drive. The question I've never see discussed is the final ratio when the Ruckstell is in under drive.
Specifically, if I put together a TT rear end using a high speed set of gears and a Ruckstell, I know that I would have a 5.0625:1 ratio in direct. What would I have in Ruckstell under? Does it end up pretty close to the same as a set of low speed gears without the Ruckstell, around 7.25:1?
Henry, here is a list that shows all of the ratios.
Just what I wanted to know! Thanks Justin!!!!
