Im considering going steeper than the stock ratio by 0.46 to add acceleration. With my new tires (33.4"), a 4.10 set would give me stock ratio but Im looking at doing 4.56's.

Do i need to be concerned with damaging the transmission due to altering shift points/lockup timing? I would imagine being under geared would cause more trouble,but id rather be safe than sorry. Input would be great!

Thanks lots,
DS

For each inch of tire you add over your stock tire size, you take away .10 of your gearing. Say you had a 31" tire with 3.73 factory gear. If you increased the tire to a 33", your gearing would be 3.53. 4.56 gears arent necessary. A 4.10 would give you plenty of acceleration, and still keep gas mileage. 4.56's are best used with 4x4's with very large tires.
