Ok here goes-- I have a 2000 Silverado shortbed reg cab with 5.3l and 4l60. Tire size is 235/65/16, it has 3.42 gears in it now and performs really well. But, would i benifit any from 3.73 gears??? I have friends that tell me they were happier with the 3.42's because the 3.73's made it feel like it topped out soon??? i just wonder with this tire size if i should stick with 3.42's. Right now @ 70 its right at 2k with the 3.42's.
