hey guys i have a 4.6 and im running 37s with stock gearing. im getting 9mpg right now city. i need more get up and go! but im looking to get the most efficient mileage most importantly. i drive on the highway ususally at about 80-90 mph and i tow my trail rig also. what would be my best option?

 

4.56 for mileage. 4.88's for towing.

 

Ok thanks my trail rig is only a Suzuki sidekick so its not a ton to tow but my trucks dogs a lot right now so I hope it will be corrected.
Any sort of numbers on mpg I've had it since its been on 37s so I never knew what decent gas mileage was like

 

Don't drive 90mph in a lifted truck might help..

 

The best way to get better mileage and performance is get rid of the lift and go back to stock tires - and use your Sidekick when you want to go offroad.
