230 of 1,094 live listings carry the Z6A GOOSENECK/5TH WHEEL PACKAGE, read from the window sticker or OEM code. Updated hourly.
Every 2025 Silverado 2500HD trim in our catalog is rated 18,500 lb conventional, whether it is the Work Truck or Custom with the 6.6L gas V8 or the LT, LTZ, High Country and ZR2 with the Duramax diesel. Two RPO codes change that: Z6A, the gooseneck / 5th-wheel package, rated 18,100 lb gooseneck, and NHT, the Max Trailering Package, rated 20,000 lb conventional and 21,600 lb gooseneck. Diesel axle ratios show a dash where the catalog value isn't confirmed against an OEM source.
Counted only when the package shows on the truck's window sticker or in its OEM option codes, not in dealer text.

One catalog configuration per trim. Each trim comes in several engine, axle, cab and bed combinations with different ratings; a truck's own window sticker has its exact ones. A dash means the figure isn’t in our catalog or isn’t confirmed against an OEM source.
Verified packages with an OEM order code and what they change for towing. A rating is shown only where every verified source for that code agrees.
