I have 3.0's now and plan on switching to 3.42's I know with 3.73's you need the gray speedo gear but what color with 3.42's?

 

anybody?

 

Many will be glad to help if you want to tell us your rear tire diameter. I don't like the old versus new gear ratio formula but it doesn't matter because they never made a 3.0:1 ratio so it would be impossible to use it.
To find speedo gears you need to provide rear tire diameter, transmission type, and rear gear ratio.

 

A proper search of this message forum will give you your answer.

 

sorry ileft the 8 off, its 3.08 gears, 700r4 and 215/70 14's
