Everyday Driveability
Research on the racetrack has helped us develop the Fortune Auto 500 Series into a great all-around shock absorber. Using high quality components that meet our strict standards allows us to optimize comfort, reliability, and longevity.

Occasional Track Use
Digressive piston technology allows for stiff low-speed compression/rebound force. This gives more control of driver inputs such as roll, dive, and squat. However, at fast stroke speeds (i.e. high speed bumps) the suspension becomes supple in response to bumps and irregularities in the road for maximum control.

Due to industry wide material shortage and global logistic delays, longer than normal lead times are temporarily expected. Most applications have a 4-8 week lead time.
