The QA1 27583-6M is a large steel monotube shock absorber from QA1's 27 Series lineup, purpose-built for stock mount racing applications on both dirt and asphalt tracks. With a compressed length of 12.8 inches and an extended length of 21.38 inches, this shock features a stud upper mount and T-bar lower mount configuration, making it a direct-fit option for a wide range of stock-mount suspension setups.

Key Features:

• Monotube design with zinc-plated steel body for excellent corrosion resistance
• 46mm hard anodized piston for durable, consistent damping performance
• 3-6M Hyperscrew valving — linear damping curve delivers complete suspension control at low shaft speeds without generating excessive forces at high shaft velocities
• Stud upper / T-bar lower mount for stock mount compatibility
• Compressed length: 12.8 in. | Extended length: 21.38 in.
• Racer revalveable and rebuildable for long-term serviceability
• Popular choice for street stocks, hobby stocks, mini stocks, and other classes requiring a stock mount shock
• Compatible with Hyperscrew (27 Series) gas pressure adjustment

The 27 Series builds on QA1's proven 26 Series platform, retaining the same reliable damping technology while adding stock mount compatibility. Linear valving provides a more stable, predictable feel, allowing the driver to better sense chassis behavior and make accurate adjustments. These shocks are backed by QA1's limited warranty against defects in materials and workmanship.
