QA1 27945-12M 27 Series Stock Mount Monotube Shock 9.17 Collapsed / 14.0 Extended Stud/T-Bar 5C-12R Linear

The QA1 27945-12M is a 27 Series stock mount monotube shock designed for circle track and performance street applications. Built on the proven platform of QA1's 26 Series, the 27 Series adds a stock mount configuration, making it a direct-fit solution for racers who need compliance without sacrificing performance.

Featuring a zinc-plated steel body for corrosion resistance and a 46mm hard anodized piston, this shock delivers consistent, repeatable damping through its linear valving with a 5C/12R (compression/rebound) tune. The linear damping curve provides complete suspension control at low shaft speeds without generating excessive forces at high shaft velocities, giving the driver a better feel for the car and a more stable, predictable handling balance.
