Changing the 3.55 gearing to 4.10:1 compensates for 33-inch tires. Mileage and performance would benefit even more from 4.56 or 4.88 gears. The 800 extra pounds of aftermarket components and accessories are like pulling an 800-pound trailer. By gearing lower (numerically higher)--rather than just matching the stock gearing--engine rpm gets closer to the torque peak.
