QA1 2693-4M 26 Series Monotube Shock 15.10in Collapsed 24.60in Extended Eye/Eye Linear 3C/4MR

The QA1 2693-4M is a race-proven, one-piece monotube shock absorber from QA1's popular 26 Series lineup. Engineered for circle track competitors, this shock delivers consistent, repeatable damping performance across a wide range of track surfaces and conditions. It features a 3C/4MR linear valving configuration, a 9-inch stroke, and eye/eye mounting at both ends for straightforward installation.

Key Features:

• 2" O.D. zinc-plated steel monotube body for durability and corrosion resistance
• Hyperscrew valve configuration — nitrogen gas pressure is sealed at the factory for consistent, sealed performance
• Deflective disc valving with linear damping curve for complete 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 rod flex and maintains valving consistency
• Can be run in any orientation — including inverted — to help reduce unsprung weight
• Replaceable 1/2" I.D. bearings for long service life
• Racer rebuildable and revalveable for unparalleled repeatability
• Uses a premium proprietary blend of specially engineered oil to prevent fade
• Eye/Eye (Eye-B/Eye-B) mounting configuration
• Collapsed length: 15.10 in. | Extended length: 24.60 in.
• Made in the USA and 100% dyno tested and serialized
• Sold individually

The 26 Series is a strong performer on rough and bumpy dirt tracks, functioning as an easy-up shock on many dirt cars, and works equally well on bumpy asphalt tracks across all banking types. It is a popular choice for modifieds, late models, super stocks, and numerous other racing classes. QA1 backs this shock with a limited warranty covering defects in materials and workmanship.
