What is a Mopar build sheet?

A build sheet is the factory's own record of how a specific vehicle was assembled. For Mopar / CDJR vehicles it lists the sales codes, option packages, trim, drivetrain, paint, and equipment the vehicle left the plant with.

It's the most reliable way to confirm how a used Chrysler, Jeep, Dodge, or RAM was originally configured — far more dependable than a badge, a trim name, or a seller's description.

What the build sheet shows

The build sheet ties each factory sales code to the package or option it represents — appearance groups, trailering and towing equipment, axle ratios, interior materials, audio and technology, and safety features.

One package name can include several smaller features, so reading the build sheet carefully tells you what the vehicle actually carries, not just what the trim badge implies.

Standard vs. optional equipment

Standard equipment follows the trim or model; optional equipment reflects choices made when the vehicle was ordered. A build sheet makes the difference clear, which matters when two trucks or SUVs with the same model name feel very different in practice.

It also helps separate factory equipment from anything a dealer or previous owner added afterward — wheels, audio, badges, and accessories may have changed since delivery.

Where else can I verify the 2KY code?

I am trying to document the original configuration of a 2022 Ram 1500. Code 2KY is shown as “Customer Preferred Package - Ky. This code identifies a factory option package or special-edition equipment group” Which source is usually most reliable when the build sheet, window sticker, and dealer printout do not use identical wording?

A window sticker is helpful for customer-facing option names, while the build sheet is usually more detailed. If they disagree, the vehicle-specific dealer equipment list can help connect the sales name to 2KY.

I would avoid buying retrofit parts until the connectors and module support are confirmed. Returning electronic or VIN-programmed components can be difficult.

This sounds more like a documentation mismatch than a decoder error. Different databases often shorten the same factory description in different ways.
