VortexMax Engine Upgrade Questions
 

Ive found out on fullsizechevy.com that the vortecmax LQ9 high output 6.0L engine package is not availavle with the z71 off-road suspension package. is that true for GMC's as well? Also, anyone drive a new 06 with this package?

I drive em all the time, I word at the dealership, it's a great engine, I believe the vortec max has a heavy duty zx3 suspension, and that is different that the z71 suspension, you can add skid plates though, but it hauls, awesome power, but just beware of gas mileage
