QA1 Precision Products 28V9M-DRY Monotube Shocks - 28 Series Pressurized - Schrader Valve

28V Series Steel Shock

QA1s 28V Series shock is the same as the 28 Series, but with a Schrader valve you can use to adjust gas pressure.

Schrader Valve*
With a Schrader valve you can easily adjust your gas pressure. Much like adding air to your car tires, the Schrader valve allows you to make on the fly gas pressure adjustments between heat races and features to adjust for varying track conditions.

Electroless Nickel Plated Body
The 28V Series is electroless nickel plated on the inside and out, encapsulating the base metal to completely seal out the elements and creating a durable, smooth finish on the inside for a consistent performance. This nickel plating provides excellent corrosion resistance, superior hardness, consistency and lubricity.

Expanded Gas Chamber
The 28V Series also features an expanded gas chamber. This expanded gas chamber eliminates the unwanted rod force increase when the shock is compressed.

Linear, Digressive and Low Speed Super
Digressive Valving Available
Digressive is the classic monotube shock feel. Linear provides a more stable car and allows the driver to feel the car better. Low Speed Super Digressive is an excellent choice when maximum rebound force is needed for big, low speed, tie-down applications.
