ACDelco Gold 18A1705 Black Hat Front Disc Brake Rotor

Independent parts catalogs cross-reference it as the front rotor for the 2014-2018 Chevrolet Silverado 1500 and 2014-2018 GMC Sierra 1500, twin trucks built on the same K2XX platform that share this front brake package. Trucks equipped with the 6-piston big-brake option are excluded and need a different rotor entirely.

Not exactly. ACDelco is General Motors' own captive parts brand, and this rotor is cross-listed under the same catalog number on GM's own dealer-parts portals. GM's own marketing describes ACDelco Gold as a high-quality alternative to the factory original-equipment casting, which uses a different coating process, rather than an identical part.

ACDelco discloses a rust-preventative black coating applied to the hat, edges, and cooling vanes, confirmed on the product image. It is a standard single-layer protective coating, not a documented premium multi-layer claim for this specific part number.

An independent parts-catalog listing publishes a tight machining tolerance for this part number, and many owners report solid, pulsation-free daily service. At least one owner forum thread documents a rotor developing pedal pulsation within a few thousand miles on these exact trucks, so results are not universal.

No. This listing is the front rotor only, sold as a single unit. Pads and hardware are separate purchases.

The Amazon listing for ACDelco Gold 18A1705 Black Hat Front Disc Brake Rotor carries a California Prop 65 warning. California requires this warning on a very wide range of manufactured goods — including rubber, vinyl, plastic, and metal automotive parts — whenever trace exposure to any of roughly 900 listed substances (commonly phthalates or heavy metals) is possible, regardless of whether the specific product poses a meaningful health risk. As a passive accessory, ACDelco Gold 18A1705 Black Hat Front Disc Brake Rotor has no Safety Data Sheet, so there's no chemistry breakdown to translate beyond that.
