Air Design GM39D99 Street Series Ground Effects Kit Satin Black

The Air Design GM39D99 Street Series Ground Effects Kit is a comprehensive aerodynamic styling package designed to transform the look and performance of your Silverado 1500. Inspired by classic lowered street trucks and modern high-performance pickups, this kit delivers a bold, aggressive stance while improving real-world aerodynamics by redirecting airflow toward the ground and away from the truck's underbody.

The front lip spoiler enhances airflow management around the engine bay and provides a noticeably sharper driving feel at medium to high speeds. Combined with the front air curtains, side skirts, and box extensions, the complete kit creates a cohesive, one-of-a-kind street truck aesthetic.
