HD models?

[RuralFireMedic]

So I'm looking for a custom grill for my 2003 Tahoe online & several of the ones I've looked at say "Not for HD models". So my question is what is a HD model? My Tahoe is one of the Z56 or special purpose vehicle (ex police vehicle). Any help would be appreciated, cause I'm anxious to find a new grill & don't want to have to go through the hassle of returning one that doesn't fit.

a 2500 HD or a 3500 HD.

there were no HD tahoes.

what he said, it says not for HD models because tahoes have the same front end as the 99-02 silverados (so same part #) and they had HDs in those which was a different grille, hood, and bumper

yep, HD was only for the pickups and burbans.
