So, i have a 2006 duramax lbz. Mine is probably the only lbz with the old style "Duramax diesel" badge that i have seen.. or better yet heard. Is this just a ealry 06 lbz? or just custom ordered?

i have the old badge like you on my 06 but it is an lly. the 06 lly and lbz are the same engine. maybe you have the lly model? what is your 8th digit in your vin. if it is a 2=lly, D=lbz. i thought all lbz's had the newer badge.

Humm, checked the vin and the 8th digit is a 2 :( ive read the 06 lly is a lesser hp tune then the lbz. The truck has the 6 speed with the manual shift function, and the high idle and all the same stuff the lbz's have (brother has a lbz same with dad and a friend and I work on them all)

Get EFI and make it a true lbz. That's what I did or you can take it to a dealer

They changed the badge in 07 cuz that was first year u couldnt get a manual trans.. So every duramax had an allison behind it.

I have a 2004.5 Duramax LLY with Allison 1000. my decal on the driver door only says Duramax Diesel. it doesnt have the allison part after. is that normal, or is that what yall are talking about?

no, what you have is a normal badge. they started putting allison/duramax on the badge because the 6 sp manual was no longer an option. So, the only combo, starting 2006.5 was the allison/duramax.
