Some Advice Gears and Tire
Hey guys I have a 2000 Jeep TJ 4.0I auto long arm 7.5 with 39 Pitbull tires. Fully built 8.8 rear and D44 for the front. It's gonna be a Street Queen no off road, mostly highway driving and city. I was thinking to change the ratio to 4.56. Would I have any problems on the highway or would it be sluggish and will my MPG be bad?
