The Front Runner Gullwing window replaces the rear window of a Land Rover Defender allowing easy access to the cargo bay via the side of the vehicle. While built for off-road durability and ease of use, the Front Runner Aluminum Gullwing Window looks smart and was designed to blend seamlessly with the exterior stylings of the vehicle. Fits in minutes, no modifications required. Sealed with the same durable, weather resistant powder coating as the Front Runner Slimline II Roof Rack. Includes 2 locking latches. The Land Rover Defender can be brought back to stock within minutes by removing and replacing with standard window.
