QA1 26912-3M 26 Series Monotube Shock Absorber 9in Stroke 12C/3MR Linear Hyperscrew

The QA1 26912-3M is a one-piece steel monotube shock absorber from QA1's 26 Series, purpose-built for circle track racing on both dirt and asphalt surfaces. With a 9-inch stroke, 12 compression / 3 mild rebound (linear) valving, and eye-to-eye mounting, this shock is a proven choice for modifieds, late models, super stocks, and a wide variety of other racing classes.

Constructed with a 2-inch O.D. zinc-plated steel monotube body, the 26912-3M offers excellent corrosion resistance and consistent damping performance across varying track conditions. This model features a Hyperscrew valve configuration — a threaded port near the bearing end of the shock body sealed with an O-ring screw — that retains nitrogen gas pressure for a firm, fade-resistant feel best suited for rough dirt tracks, easy-up applications, and bumpy asphalt tracks of all banking types.

Key Features:

• One-piece steel monotube body — 2" O.D. zinc-plated for corrosion resistance
• 9-inch stroke with compressed height of approximately 15.10" and extended height of approximately 24.60"
• 12C / 3MR linear valving — deflective disc design for controlled suspension response at all shaft speeds
• Hyperscrew gas pressure retention — sealed nitrogen charge for consistent, non-fading performance
• 15mm centerless ground, hard chrome plated piston rod — eliminates piston rod flex and increases valving consistency
• Eye/Eye (Eye-B/Eye-B) mounting — compatible with standard circle track suspension setups
• Can be run in any orientation — mount upside down with no change in rate to reduce unsprung weight
• Racer revalveable and rebuildable — allows for ongoing tuning and long service life
• Popular for modifieds, late models, super stocks, and other sanctioned classes

The QA1 26 Series delivers professional-level damping technology at an accessible price point, making it a competitive choice for racers looking to maximize chassis performance on a budget without sacrificing consistency or durability.
