QA1 Proma Star Series Single Adjustable Coil-Over Shock, Bearing Mount, 11.625in/16.875in - DS501

The QA1 Proma Star Series single adjustable coil-over shock (MPN: DS501) offers a versatile suspension solution for custom chassis builds and performance upgrades. Designed to provide simultaneous tuning of rebound and compression through a single adjustment knob, this shock allows you to balance ride comfort and handling performance quickly without complex multi-way adjustments.

This shock features a bearing mount configuration to minimize deflection and improve suspension articulation, especially in applications requiring misalignment. With an 11.625-inch compressed length and a 16.875-inch extended length, it provides the necessary travel for a variety of street and track setups. The included hardware kit allows for precise ride height adjustment when paired with a standard 2.5-inch I.D. spring (sold separately).

• Single Adjustable Valving: Adjust rebound and compression simultaneously with one knob for simplified tuning.
• Bearing Mount Design: Spherical bearings reduce play and deflection compared to traditional bushings.
• Precision Construction: All Proma Star shocks are made in the USA and dyno-tested to ensure consistent damping.
• Adjustable Stance: Included threaded collar and hardware kit for easy ride height modification.
• Dimensions: 11.625-inch compressed / 16.875-inch extended.
• Manufacturer Part Number: DS501
• Warranty: Eligible for a Limited Lifetime Warranty (registration required at QA1.net/warranty).

Note: Ensure your suspension geometry provides adequate travel to avoid overextending or bottoming out the shock assembly.
