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

The QA1 2675-7C is a 26 Series one-piece steel monotube shock designed for circle track racing, delivering consistent, high-performance damping in a durable, budget-conscious package. With a 7-inch stroke, 13.40-inch collapsed length, and 20.63-inch extended length, this shock features eye/eye mounting on both ends for straightforward installation in a wide range of applications.

Built with a 2-inch O.D. zinc-plated steel monotube body, the 2675-7C offers excellent corrosion resistance and one-piece construction for long-term reliability. The Hyperscrew valve configuration features a threaded port sealed with an O-ring screw near the bearing end, keeping nitrogen gas pressure securely locked in. This sealed design is compliant with IMCA sanctioning body rules when used in sealed Hyperscrew form.

Key Features:

• 5C/7C linear-digressive valving via deflective disc technology for precise control at all shaft velocities
• 46mm piston for maximum car control and stable, consistent damping
• 15mm centerless ground, hard chrome-plated piston rod eliminates rod flex and improves valving consistency
• 2-inch O.D. zinc-plated steel body resists corrosion for extended service life
• Hyperscrew gas port seals nitrogen pressure — IMCA legal in sealed configuration
• Can be run in any orientation, including inverted, to reduce unsprung weight
• Replaceable 1/2-inch I.D. bearings for easy maintenance
• Racer rebuildable and revalveable for consistent, repeatable performance
• 100% dyno tested and serialized at the factory
• Made in the USA

The 26 Series is a popular choice for modifieds, late models, super stocks, and similar 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. Eye/eye (Eye-B/Eye-B) mounting provides versatile fitment across a variety of race car suspension setups.
