Description

QA1 27 Series shocks are stock-mount monotubes featuring zinc plated bodies, 46mm hard anodized pistons, and multiple valving options. Their versatile mounting configurations make them great choices for multiple Circle Track racing classes—making it simple for racers to get on the track and achieve the performance they want. Available in hyperscrew and sealed hyperscrew, QA1 27 Series shocks are a popular option for street stocks, hobby stocks, mini stocks, and other classes that require stock mount shocks.

QA1 27 Series shocks also feature:

* Deflective disc valving
* Damping curve allows for complete control of suspension at low shaft speeds without creating extreme forces at high shaft velocities
* Linear valving provides a more stable car and allows the driver to feel the car better
* Non-fading
* Racer-designed revalveable and rebuildable parts for unparalleled repeatability
* 100 percent dyno-tested and serialized

Product Overview

The 27 Series is a brand new stock mount monotube shock. Featuring a zinc plated body, 46 MM hard anodized piston and multiple valving options, the 27 Series works like our tried and true 26 Series, but with stock mount option. They are zinc plated for corrosion resistance, and are a popular choice for street stocks, hobby stocks, mini stocks and other classes that require a stock mount shock. These shocks are available with Hyperscrew (27 Series), or Sealed Hyperscrew (27A Series) (IMCA Southern Sport Mod legal) Hyperscrew. The damping curve allows for complete control of suspension at low shaft speeds without creating extreme forces at high shaft velocities. Linear valving provides a more stable car and allows the driver to feel the car better. They are racer revalveable and rebuildable, designed for unparalleled repeatability. Made in the USA, these shocks are 100% dyno tested & serialized.
