QA1 27883-5M 27 Series Monotube Shock Absorber Stud/Poly 12.8 x 21.38 in. 3C/5R

The QA1 27883-5M is part of QA1's 27 Series — a stock-mount monotube shock absorber built for performance street and competition applications. Featuring a zinc-plated steel body and a 46mm hard-anodized piston, this shock delivers consistent, precise damping in a durable, corrosion-resistant package.

The 27 Series builds on the proven foundation of QA1's 26 Series design, adding a stock mount configuration for direct-fit installation. This unit is valved at 3 compression / 5 rebound (3C/5R) and features a stud upper mount paired with a polyurethane lower bushing for reduced noise, vibration, and harshness (NVH) while maintaining performance feel.

Key Features:

• Monotube shock design for superior heat dissipation and consistent performance
• Zinc-plated steel body for corrosion resistance and long service life
• 46mm hard-anodized aluminum piston for durability and smooth travel
• 3C/5R valving (3 compression / 5 rebound) for a performance-tuned ride
• Stock mount / stud upper mount for bolt-in installation
• Polyurethane lower bushing reduces NVH and improves handling response
• Compressed length: 12.8 in. | Extended length: 21.38 in.
• Linear valving for predictable, consistent damping characteristics
• Made in the USA by QA1 Precision Products

QA1's 27 Series shocks are engineered for enthusiasts who demand performance without sacrificing drivability. Built and valved in the USA, these shocks are an ideal upgrade for street machines, muscle cars, and circle track applications requiring a stock-mount solution.
