I just bought a 2006 Silverado 1500 4x4. I was checking out the RPO codes in my glove box yesterday and noted that I have the Z85 RPO code. I was told by the dealer that I have the factory installed trailer package with hitch, electrical connection, high capacity air cleaner and external transmission oil cooler. However, I do not have the RPO codes for the HC air cleaner nor the ext. tranny cooler. So my question is this:

Does the Z85 RPO code automatically include those things since it is a trailering/handling package?

Thanks.

 

Ask the dealer!

 

I think it does.

Take care and God bless,
