I am seriously considering buying Ben's box for my truck. My question is is it worth it on a 550 hp street truck? My truck just seems to hang out and rev and if a lockup box on a duramax makes anywhere near the difference it does in the way the truck pulls as it does on my buddies cummins (don't see why it wouldn't) then i think im gonna get one. Anyone on here with one have any input?? :thumb:
