Window Quarter Molded LH North American Sportsman

The Window Quarter Molded LH North American Sportsman from FIVESTAR is a driver-side quarter window panel engineered for serious racers and restoration enthusiasts building high-performance vehicles. This left-hand molded quarter window serves as a critical aerodynamic and safety component in purpose-built race cars, particularly North American Sportsman-class vehicles where weight reduction and airflow management directly impact lap times. Whether you're constructing a vintage-inspired competition platform or restoring a classic with modern performance upgrades, this polycarbonate quarter window delivers the precision fit and durability race teams demand.

Manufactured from 0.093-inch-thick polycarbonate with a mar-resistant surface treatment, this window resists scratching and impact damage during high-speed operation and pit work. The pre-cut and drilled configuration means zero fitment guesswork—the molded profile matches your greenhouse roof geometry precisely, while integrated mounting holes align with factory or cage tube locations. The blackout border reduces glare and unwanted light transmission into the cockpit, improving driver focus during intense racing conditions. Clear optical clarity in the main viewing area ensures unobstructed sight lines for mirror and peripheral vision, critical for safe vehicle control.

This component is ideal for competitors running Sportsman-level stock cars, dirt modified platforms, and restomod builds where lightweight, durable greenhouse components are non-negotiable. The left-hand driver-side orientation makes it a direct bolt-in for vehicles originally equipped with standard quarter windows or for cage-mounted installations common in race car builds. Compact dimensions (14.6 × 1.05 × 25.7 inches) and minimal weight (0.93 lbs) contribute to chassis balance without sacrificing structural integrity. Installation requires standard fasteners and basic hand tools, making it accessible to shop crews with fabrication experience.
