QA1 DK22-GMB5 Drag Racing Double Adjustable Rear Coilover Suspension Kit

The QA1 DK22-GMB5 is a complete drag racing rear suspension kit engineered for serious performance on the strip. Designed and manufactured by QA1 Precision Products — a trusted name in American motorsports — this kit replaces factory suspension components with purpose-built hardware optimized for consistent, repeatable launches and maximum weight transfer.

QA1 drag suspension kits are built around double adjustable shock absorbers, allowing independent tuning of both compression and rebound damping. This level of adjustability lets racers dial in the perfect suspension tune for varying track conditions, vehicle weight, and power levels — without replacing components.

Key Features:

• Double adjustable shocks — independent compression and rebound tuning for precise launch control
• Heavy-duty chromoly steel construction for strength under high-horsepower applications
• Bolt-on installation designed to work with stock mounting locations
• Compatible with leaf spring or coilover rear suspension configurations (per application)
• Manufactured in the USA by QA1 Precision Products
• Optimized for drag racing weight transfer and 60-foot performance

QA1's drag kits are a popular upgrade for GM muscle cars and performance vehicles where consistent, tunable rear suspension is critical to putting power to the pavement. Whether you're bracket racing or all-out competition, the DK22-GMB5 provides the adjustability and durability needed to stay competitive.
