Got a cracked or scratched rear window on your Chevy Silverado or GMC Sierra? This is a genuine OEM replacement right rear door glass with 20% factory-style tint, perfect for 2019-2021 Crew Cab models. Part numbers 84560284 and 23379198 cross-reference directly. It's brand new OEM quality but comes in generic packaging – same great glass, just without the fancy box. Direct fit means no modifications needed; just remove the old one and install this. The tint matches most factory windows, giving you privacy and UV protection. Ideal for accidents, vandalism, or wear and tear. Keep your truck looking clean and legal. Note: This is for the right rear door only, crew cab configuration. If you're handy with trim tools, you can DIY; otherwise, a pro can knock it out fast. A must-have for any Silverado/Sierra owner dealing with window damage.
