QA1 2675-2 26 Series Steel Monotube Shock 7in Stroke 5C/2R Digressive Hyperscrew

The QA1 2675-2 is a 26 Series one-piece steel monotube shock absorber engineered for circle track racing. With a 7-inch stroke, 5C/2R digressive valving, and a hyperscrew gas port, this shock delivers precise, consistent damping whether used as a primary shock or a traction shock across a wide range of track surfaces and conditions.

Key Features:

• 2" O.D. zinc-plated steel monotube body — corrosion-resistant one-piece construction for long-term durability
• 7-inch stroke — 13.10" collapsed / 20.57" extended length with eye/eye mounting
• 5C/2R digressive valving — delivers maximum car control at all shaft velocities with a damping curve optimized for low-speed suspension control without excessive high-speed forces
• 46mm large-bore piston — provides unmatched, stable valving consistency throughout the full range of motion
• 15mm centerless-ground, hard chrome-plated piston rod — eliminates rod flex for repeatable, accurate valving
• Hyperscrew gas port — sealed with an O-ring screw to lock in nitrogen gas pressure; adjustable only by QA1 or authorized rebuilders (IMCA legal sealed version available)
• Deflective disc valving — digressive configuration for precise control at both low and high shaft speeds
• Racer rebuildable and revalveable — can be rebuilt and revalved for unparalleled repeatability and tuning flexibility
• Can be mounted upside-down — reduces unsprung weight for improved handling
• 100% dyno tested and serialized — every unit verified before it leaves the factory
• Made in the USA

The QA1 26 Series is a go-to choice for modifieds, late models, super stocks, and various other racing classes. It performs especially well on rough dirt tracks, as an easy-up shock on dirt cars, and on bumpy asphalt tracks across all banking types. Proprietary engineered shock oil prevents fade, ensuring consistent performance heat after heat.
