Actually, the 450 is better suited than the 550. the 550 has a 4. 88 ratio for the highest gearing. . Only allows you do do 75 tops. my best friend's dad just sold his. the 450 has an option for like a 4. 30 and I want to say a taller one than that as well, but as far as trucks, I would probably go with a 450, 2L conversion, with full quill ostrich seats, and all the goodies to go with it! Hey Bighammer. I was just pullin your leg!!!
