QA1 2699-4M 26 Series Steel Monotube Shock 15.40 Collapsed / 24.63 Extended Eye/Eye 9C/4MR Linear Hyperscrew

The QA1 2699-4M is a one-piece, steel-bodied monotube shock from the 26 Series lineup, engineered for competitive circle track and dirt racing applications. With a 15.40" collapsed length and 24.63" extended length (9" stroke), eye-to-eye mounting on both ends, and 9C/4MR linear valving, this shock delivers consistent, tunable damping performance on a wide range of track surfaces.

Key Features:

• 2" O.D. zinc-plated steel monotube body for corrosion resistance and long service life
• Hyperscrew valve configuration — a threaded port near the bearing end sealed with an O-ring screw to contain nitrogen gas pressure
• Deflective disc valving with linear tune — provides complete suspension control at low shaft speeds without creating extreme forces at high shaft velocities
• 46mm piston for maximum car control across all shaft velocities
• 15mm centerless-ground, hard chrome-plated piston rod eliminates piston rod flex and maintains valving consistency
• Premium proprietary oil blend prevents fade during extended racing use
• Can be run in any orientation, including inverted to reduce unsprung weight
• Replaceable 1/2" I.D. bearings with eye-to-eye (Eye-B/Eye-B) mounting
• Racer rebuildable and revalveable for repeatable, on-track performance
• Made in the USA — 100% dyno tested and individually serialized

The QA1 26 Series is a popular choice among modifieds, late models, and super stocks. It performs especially well on rough and bumpy tracks — both dirt and asphalt — and excels as an easy-up traction shock in a variety of racing classes.
