I would say yes. Jeep doesn’t struggle at all and it uses all 8 gears. It accelerates just as fast on the on-ramps and passes cars easily on 2 lane roads. This thing is just a brick at highway speeds and the lift, tires, wheels, armor, etc all combine to kill the MPG.were the gears worth it?
My question is... do you need gears? Do you get better mileage with 37s if you regearAnd just an FYI for those wondering about MPG. Don't necessarily believe the high numbers people claim to get. Are they hand calculating and did they add a Tazer or something similar to adjust tire size, gear ratio to get the odometer/speedo right? My numbers are low and it's due to all my extra weight and lift height. But, my tire size and gear ratio is adjusted via a Tazer, speedo is GPS verified and I hand calculate my MPG. I hit 8th gear by 50mph and just purrs along nicely at that speed. I knew I wouldn't get stock MPG numbers ever again, but I'm ok with that.
You need gears in order for the engine and trans to “try” and work like normal. You’ll never get the stock 4.10’s to push the 37’s as nice as 4.88’s will. Simple physics. I’d do it again.My question is... do you need gears? Do you get better mileage with 37s if you regear
