if you have a 486 ring and pinion you will be close with the gear recomended if you have a 411 ring and pinion go up on that gear 40 to 50 points 680 or so.

differences between 4.11 and 4.86

if you have a 486 ring and pinion you will be close with the gear recomended if you have a 411 ring and pinion go up on that gear 40 to 50 points 680 or so.

I have been experiencing that as well, needing a little more gear with my new 4.11 winters QC. It has been about 40-50 points more than what guys are running with their 4.86 QC

What is this all about? any ideas?

Call franklin we wasted a couple of nights not knowing there is a difference,and I can't remember all of what they told us but we started using the right gears the problem goes away,and u also have to watch who you ask about gears there is alot more 411 gears than in the past.
