Shock absorbers are quite possibly the most vital suspension component of any vehicle, whether it be street, circle track or drag strip. Shocks smooth out the bumps and ensure power is delivered where it is needed. This clip from our friends at QA1 Precision Products displays a few differences between twin tube and monotube shocks.
The cost effective twin tube design is most commonly used in today’s cars, trucks and SUVs. Used in a dirt racing application the twin tube layout has the ability to get the car “into” the track erasing that “floaty” feeling on a smooth, slick track. Furthermore, the body of the twin tube design can be dented and still function properly. If your running an open wheel race car, that could save you a lot of headaches. However, if you typically race on a rough surface twin tube shocks are not ideal.
The more aggressive monotube shock design has an area of gas and oil separated by a floating piston. On a rough race track the monotube shock can be more effective at handling the ruts without “digging” in and upsetting the attitude of the car. The monotube arrangement is also less likely to heat up than it’s twin tube counterpart, ensuring the component operates more effectively without performance fade.
While both have their advantages and disadvantages, the deciding factor can be most likely driver preference. Whatever your preference may be, QA1 specializes in performance suspension components and has an extensive catalog to fulfill all of your suspension needs.
