DIGRESSIVE* All Fortune Auto shock absorbers use Digressive piston technology. This technology allows for stiff low speed rebound force which helps give better control of driver inputs such as roll, dive and squat. However, at fast stroke speeds (i.e. high speed bumps) the suspension is kept supple in response to bumps and irregularities in the road.

FORTUNE AUTO 510 SERIES COILOVERS© -$1,699

510 series coilovers incorporate a "ULTRA" DIGRESSIVE* piston, 24-way damping, custom rates & a one year warranty

510 Series coilovers are CUSTOM built to order.



Incorporates all the great features of our 500 series coilovers. Furthermore it includes our new "Ultra" Double Digressive Pistons.

Featuring our new "Ultra" Double Digressive Piston (UDDP) with revised shim stacks, this "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, we are proud 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.
