Product Details

Featuring the new "Ultra" Double Digressive Piston (UDDP) with revised shim stacks, Fortune Auto's "Ultra" Digressive piston allows for massive amounts of low speed rebound force that helps with driver inputs such as dive, pitch and roll. Furthermore, the rebound force greatly tapers off to provide the driver with "blow off". This helps with large impacts on track helping the vehicle stay settled after hitting curbing at high speeds. After countless hours on the shock dyno and testing on the track, they are able to offer these high performance coilovers that rival many high end European shocks that cost several thousand dollars more. Due to the ultra digressive nature of this shock absorber, this product is recommended for track use only.
