QA1 26A72-9 26A Series IMCA-Legal Steel Monotube Shock Absorber 7in Stroke Eye/Eye

The QA1 26A72-9 is a one-piece steel monotube shock absorber built for circle track racing with IMCA-legal compliance. Part of QA1's 26A Series, this shock shares the same proven construction as the standard 26 Series but is fitted with a sealed hyperscrew configuration that locks gas pressure tuneability — meeting IMCA sanctioning body regulations out of the box.

With a 7-inch stroke, a collapsed length of approximately 13.09 inches, and an extended length of approximately 20.57 inches, this large-body shock mounts via eye/eye (Eye-B/Eye-B) ends for broad compatibility across common circle track suspension setups.

Key Features:

• One-piece 2-inch O.D. zinc-plated steel monotube body for corrosion resistance and durability
• IMCA-legal sealed hyperscrew — gas pressure fixed per sanctioning body rules; adjustable only by QA1 or authorized rebuilders
• Deflective disc valving with a 9-2 valving configuration (compression/rebound)
• 46mm piston for stable, consistent damping at all shaft velocities
• Centerless-ground, hard chrome-plated, gun-drilled piston rod to minimize flex and maintain valving consistency
• Premium proprietary shock oil formulation resists fade under sustained racing conditions
• Can be mounted upside-down with no change in damping rate, helping reduce unsprung weight
• Racer rebuildable and revalveable for long-term consistency
• Replaceable eye-style bearing ends
• 100% dyno tested and serialized — Made in the USA

The 26A Series is a go-to choice for modifieds, late models, super stocks, and similar classes competing on dirt and asphalt tracks. It performs especially well on rough or bumpy tracks and as an easy-up shock on dirt cars, making it a reliable and rules-compliant option for competitive circle track racers.
