QA1 26912-4M 26 Series Steel Monotube Racing Shock 9in Stroke 12C/4MR Hyperscrew Eye/Eye

The QA1 26912-4M is a 26 Series steel monotube racing shock absorber featuring a 9-inch stroke, 12-compression / 4-rebound (12C/4MR) linear valving, and a Hyperscrew gas pressure port with Eye-B/Eye-B end mounts. Designed for circle track competitors, this shock delivers consistent, tunable damping performance on both dirt and asphalt surfaces.

Built with a 2" O.D. zinc-plated steel monotube body, the 26 Series provides excellent corrosion resistance while keeping weight manageable. The one-piece monotube design eliminates the need for a secondary tube, resulting in a compact and robust shock that can be run in any orientation without a change in damping rate. A 15mm centerless ground, hard chrome plated piston rod eliminates piston rod flex to maximize valving consistency lap after lap.

Key Features:

• 2" O.D. zinc-plated steel monotube body for strength and corrosion resistance
• 9-inch stroke with 15.10" collapsed / 24.60" extended length
• 12 compression / 4 rebound (12C/4MR) linear deflective disc valving
• Hyperscrew gas pressure port — sealed with an O-ring screw to retain nitrogen pressure
• 15mm centerless ground, hard chrome plated piston rod for reduced flex and consistent valving
• Eye-B/Eye-B end mounts for direct bolt-in installation
• Can be run in any orientation with no change in damping rate
• Fully user-rebuildable and revalvable
• American made

The 26 Series is a popular choice for modifieds, late models, super stocks, and various other classes. It performs especially well on rough tracks, as an easy-up shock on dirt cars, and on bumpy asphalt tracks across all banking types.
