Who It's For

This set is best for owners of the GMC Sierra 2500HD or 3500HD Crew Cab from 2020 through 2026 who want functional protection from rain and sun and a clean, factory-like look. It suits truck drivers who frequently drive with windows slightly open for ventilation or who work in conditions where rain, spray, or glare are common.

Those who drive other truck models or non-crew cab configurations should look for guards matched to their vehicle; because this product is a custom fit, it will not suit other makes or years.
