Circle Track Twin Tube vs Monotube Shocks

Many people wonder what the difference is between monotube and twin tube shocks and what will work best for circle track racing. It really comes down to preference.

Generally speaking, monotube shocks have the benefit of a larger diameter piston. The larger piston can react to bumps and ruts quicker than a twin tube piston, which can result in increased consistency. Monotube shocks are generally preferred on rough tracks but can and do work well on slick tracks as well.

On the other hand, twin tube shocks provide a more direct feel to the driver. Drivers commonly describe being able to feel the bumps of the track better and can easily tell when and how much throttle to apply.

The biggest distinguishing feature between the two styles it that in a monotube, the piston rides directly on the inside wall of the shock body. In a twin tube, the piston rides inside a compression tube which is spaced slightly in from the wall of the shock body.
