QA1 26V97-4M 26 Series Monotube Shock Absorber 9in Stroke Schrader Valve 7-4M Valving Steel

The QA1 26V97-4M is a 26 Series one-piece monotube shock absorber engineered for circle track racing applications. Built with a 2" O.D. zinc-plated steel monotube body, this shock delivers consistent, tunable damping performance across a wide range of track conditions — from rough dirt ovals to bumpy asphalt tracks of all banking types.

This unit features a Schrader valve for quick, tool-free gas pressure adjustments between heat races and features, allowing racers to dial in performance on the fly without specialized equipment. The shock measures 15.63" compressed and 24.63" extended, providing a 9-inch stroke, and mounts via eyelet (Eye-B) top and eyelet (Eye-B) bottom hardware. Valving is set at a 7-4M linear configuration.

Key Features:
