Drag Configuration

Features rod ends on both upper and lower control arms to reduce deflection and improve weight transfer. This configuration offers a 0-2" adjustable drop and is designed for increased rear grip during hard launches.

Handling Configuration

Includes poly bushings on the lower control arms for improved cornering and reduced noise, vibration, and harshness (NVH). A heavier spring rate offers more stability, with 0-2" or 2-4" drop options available.

Made in the USA

QA1 systems are proudly made in Lakeville, Minnesota, and come with a Limited Lifetime Warranty on shocks.
