Do you trust automakers when they say cosmetic manufacturing changes don't affect quality?

General Motors has changed the spray-on bedliner application process for Chevy Silverado and GMC Sierra trucks built during the 2026 model year. The revised method uses a different masking system, producing a softer, more gradual bedliner edge rather than a distinct line.

Why it matters

The change applies to Silverado 1500, 2500HD and 3500HD models and Sierra 1500, 2500HD and 3500HD models with RPO code CGN factory spray-on bedliners. GM says the new process eliminates approximately 2.5 million pounds of landfill waste annually at each assembly plant, and it does not affect bedliner durability.

The change covers RPO code CGN spray-on bedliners on 2026 model year Silverado and Sierra trucks in the 1500, 2500HD and 3500HD configurations. GM says the process eliminates about 2.5 million pounds of landfill waste each year at every assembly plant.

The players

General Motors

General Motors is the Detroit automaker behind the Chevrolet Silverado and GMC Sierra full-size pickup trucks, which are among the best-selling vehicles in the United States.

The details

GM replaced its previous tape-and-wire masking with a different masking system during spray-on bedliner application. The new method creates a gradual transition along the bedliner edge instead of a sharp line. GM rolled the change out across its assembly plants during 2026 model year production rather than all at once. GM confirms the softer edge is normal and does not indicate a manufacturing defect.

The revised process was implemented during the 2026 model year.

The Home Front

Full-size pickups such as the Silverado and Sierra are a common household vehicle for towing and hauling, so manufacturing details like bedliner finish matter to many owners. This process update reflects automakers reducing production waste as a routine part of plant operations.

If you own a 2026 Silverado or Sierra with a spray-on bedliner, expect a softer edge along the bedliner and know it is normal. No bedliner-specific repair is needed, so keep your warranty paperwork on file in case a question comes up at the dealership.

The takeaway

A softer bedliner edge on a 2026 Silverado or Sierra is expected and does not affect durability. If you have questions about your truck's finish, bring your vehicle identification number to your dealership service department.
