    RPO for the engine is L76:

    1 - Requires (M70) 4-speed automatic transmission, (GT5) 4.10 rear axle ratio and (Z55) Autoride Suspension Package.

     

    Hope this helps

     

    Thanks JDG. That is exactly what I was looking for. I certainly appreciate you looking that up.

     

    I know the 3LT description...does the "1LZ" model = the LTZ?

     

    Thanks again.

     

    Yep, LTZ-1LZ. Like the LT groups are 1LT,2LT,3LT it's just the LTZ only has 1 for now.

     

    Your not getting rid of the SS are you? I do like the new Avalanches, fortunately no one around here knows you can get the 6.0 in them or I might seriously look at one.

  3. I couldn't imagine you getting rid of your truck with all the work you've done to it. But, if you want to know the RPO for the aluminum block engine is LH6. According to the online order reference guide it is only available in the CK10543 truck which is the 4x4 crew cab. I hope this helps and please keep your truck, it's awesome!

  4. Dumped mine and it sounds awesome!

    mounting your mufflers like this will cut down on the drone quite a bit.. :smash:

    you get a lot of sound waves comming from the top and bottom of the muffler and it bounces up aginst the bed, stacked like that the sound waves go out the side of the truck making it quieter. off setting the mufflers some about 1/3 from each outher helps even more, less sound waves trapped between the mufflers......

     

    :seeya:

     

    You are right. I have no resonance in the cab. Before I did this is was really bad. Outside it is a lot louder, and has a lot deeper sound to it. You can feel it inside the cab more than hear it. Of course, I've got about 3 rolls of dynomat in my cab also.
