  1. No Plows on a crew cab diesel???????

    04.5-05 LLY Duramax Powertrain
    What is the deal with no snow plows on a crew cab Diesel? The dealer today told me can not install a plowdue to frame failures "cracking" where it is doubled together. Is this for real a 3/4 ton truck that does not have a trong enough frame to snow plow with?? unbelievable!!

    I know.................. this issue has been beat to death on here. But I've been looking for some info that I just haven't been able to find. Ported stock mouthpiece VS the LBZ Mouthpiece. Anyone have any concrete data on this? Temperatures Horsepower Torque Dyno sheets Anything? Any help...
