4:10 rear end

1547 1
When I order a wrangler rubicon automatic it comes standard with 3:73, when I upgrade it to 4:10 it comes in on the order as 4:10 rear axle, what about the front? They have match don't they?

Welcome to Allpar. Yes, the front and rear gear ratios and the tire sizes have to match for a 1:1 ratio.
