Moved to the correct section. What gears do you have now?

 

If you have a 2010 sport then you most likely have 3.55 gears. if you want better towing with the 37's, I would go to 4.10 gears. Gas mileage is not going to be a major game changer.... you might see 1 more mpg if you still want to tow. the 3.55 gears are best for non towing highway driving. the factory 3.92 gears are best for around town and towing. either way gas mileage wont be any better then stock.

 

With 37 inch tires, I would be much more tempted to go with 4.56 gears, if they are available for his axles.......
