thanks for the replys guys if this was my truck i'd get one of those and put on it but since its the company's i dont see them spendin the money on it at all

as fas as putting a dt466 in it i dont think so. we have two trucks with those in them and i can pass them pulling hills around here and my truck weighs just as much if not more....i do like the dt466 will turn more rpm tho

 

If you have a 3126 passing a mechanical DT466, then something's wrong, or its power is rated real low.
