I gotta agree here. My 1/2 ton didnt seem to happy at 50, better at around 45 and the gear ratio was a better then what a 1 1/2 ton would have. The 1/2 ton was 4.11 while the 1 1/2 would start at 5.14 or 6 something in low. Remember a 2speed wont go faster, just gets you going better when hauling. Bigger tires will help the speed but will throw off the speedometer. I would think 45 would be to fast for it with stock tires...
