QA1 Proma Star Series Double Adjustable Coil-Over Shock - Bearing Mount - 11.625in/16.875in (DD501)

The QA1 DD501 Proma Star Series Double Adjustable Coil-Over Shock is engineered for custom chassis and suspension builders who require precision valving control. This aluminum-body shock features independent compression and rebound adjustment knobs, allowing you to dial in specific handling characteristics for the street, drag strip, or road course without removing the unit from the vehicle.

Equipped with bearing mounts to minimize deflection and accommodate misalignment, this shock provides a stable platform for high-performance applications. The threaded body allows for quick ride height adjustments to achieve the perfect stance and corner balance. To complete your setup, this shock requires a 2.5-inch inner diameter (I.D.) spring in the appropriate length and rate for your vehicle's weight and intended use.

• Double-Adjustable Valving: Independent tuning of rebound and compression for maximum chassis control.
• Technical Specs: 11.625-inch compressed length and 16.875-inch extended length.
• Bearing Mounts: Spherical bearings reduce friction and mount deflection compared to standard bushings.
• Quality Assured: All units are dyno tested to ensure consistent performance and are manufactured in the USA.
• Warranty: Eligible for QA1's Limited Lifetime Warranty (registration required).
• Manufacturer Part Number: DD501

Note: Please verify your suspension travel requirements to avoid overextending or bottoming out the shock. 2.5-inch I.D. springs and spanner wrenches are sold separately.
