Differentials: open vs limited slip - Page 2

Old 'n Rusty · 11-12-2007, 01:47 AM

Mine was a rather low 411 but most are the same as mine is now: 354. My speedo was reading way too high before and now is about 10 percent low. The getrag tranny does not like low rpm's and was not happy with the wider spacing between the gears with the 354 gears. Now it is much happier as I can increase the rpm's before shifting.

hey, great start on a article and very well articulated. I would think you are a master mechanic, seriously. Thanks for the education to me and many others out there that needed refreshing or an all out education on such clutches.
