If you’re looking to give your classic Chevy or GMC a breath of fresh air, check out this sliding rear window from Brothers. With its 4-panel design, you’re getting one of the widest openings you can find, which is perfect for those hot summer days when you just want to let some air flow through. The frame is made of powder-coated aluminum, so it’s tough and ready to handle whatever you throw at it, whether that’s a rough back road or just the wear and tear of daily driving.

One of the best parts? It uses the stock weatherseal, so you won't have to worry about any annoying leaks or drafts when you’re cruising down the highway. The narrow stiles and tight-sealing weatherstrip make sure everything fits snugly, keeping the elements out while still letting you enjoy the open air.

• Chevrolet Blazer (1973-1974 & 1987)
