All Fortune Auto shock absorbers use Digressive piston technology. This technology allows for stiff low speed compression/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.The ability to upgrade to 2-Way canisters at any time ensures that your investment is a sound one. Update your shocks without the need of investing into a complete new coilover system: simply send your 500 series shocks into our service center for the modular 2-Way upgrade. All 500 series dampers are fully rebuildable, serviceable, and can be custom valved at any time. Please consult our 2-Way application list for more details and availability. 500 series damper shaft seals have 40% less drag than our previous models. This provides for less hysteresis and for superior control of driver inputs. Our new seals are made of a specially formulated Buna rubber compound that provides a great balance between reliability and performance! Since the shaft seal is the most important seal on the shock, a stronger seal will greatly improve quality and performance.

Custom Spec Valving Options
500 SERIES - GENERATION 5 UPDATES
Ultra Precise Shim Stacks
Shims are deflection disks that cover up the port holes on a piston. They regulate the fluid flow which generates the force found in a damper. "Valving" or "re-valving" of a shock is accomplished by using a variety of shims that will ultimately provide enough resistance and damping ability for a particular application. Minute differences in the shims' diameter and thickness are very critical; just a thousandths of an inch of variation in the dimensions can change a damper's force profile up to + or - 25%. The shims' consistency is crucial in matching shock absorbers to one another. Generation 5 dampers utilize a high-grade shim material made of Sandvik steel, ensuring precision matched dampers.
Lightweight Internal Floating Piston
The new Generation 5 Internal Floating Piston is considerably lighter and uses a low-drag teflon band that drastically reduces stiction. This allows the damper to react quicker to shock forces.
