Air Design GM40A31PR Fender Vent Set Unpainted GMC Sierra 1500

The Air Design GM40A31PR is a two-piece front fender vent set designed to deliver both performance-inspired styling and genuine aerodynamic function for the GMC Sierra 1500. Arriving in an unpainted, paint-ready finish, these fender vents replace the factory fender appliques and give your truck the aggressive look of purpose-built racing vents.

Engineered and manufactured in-house at Air Design's North American facility, these vents are built to contribute to better ventilation of the engine bay and help release trapped air pressure from the wheel arches — reducing lift and improving overall aerodynamics.

Key Features:

• Unpainted / Paint-Ready Finish: Arrives primed and ready to be painted to match your vehicle's factory color
• Dual-Material Construction: Built from a combination of high-strength elastomeric polyurethane and ABS plastic for impact resistance and long-term durability
• Weather-Resistant: Both materials resist rust, corrosion, and deterioration from the elements
• Functional Aerodynamics: Designed to relieve wheel-arch air pressure buildup, reducing drag and improving performance
• Engine Bay Ventilation: Contributes to improved cooling and airflow through the front fender area
• OE-Style Fit: Precision-engineered for a factory-spec fitment with no gaps or misalignment
• Hardware Included: Comes with installation instructions, double-sided 3M tape, and urethane adhesive

Installation requires drilling and takes approximately one hour. Air Design backs this product with a 3-year / 36,000-mile limited manufacturer's warranty against defects in materials and workmanship for the original purchaser.
