The 21st century is known for innovations in shock absorbers. The shock absorbers and the structure of the car are also friendly, and the owner can replace or adjust or replace the shock absorbers themselves. The shocks are available in single-adjustable and dual-adjustable configurations.

Dual adjustable dampers are able to trim bumps and rebound separately. However, a single adjustable shock allows changing the rebound portion of the shock. Single-adjustable shocks are more expensive than traditional or non-adjustable shocks and very cheap compared to dual-adjustable shocks.

The rear shock is also important in the traction equation and also provides a slightly longer extension to prevent bottoming out when planting tires, especially when the tire and body are separated at start-up, the shock has more than 100% anti-squat.
