*Upgradeable to 2-Way canisters at any time, insuring that your investment is a sound one. Update without the need of investing into a complete new coilover system down the road; just send your 510 series shocks into our service center for the modular 2-Way upgrade. All Generation 4 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.
When the Fortune Auto engineers designed the Generation 4 Series, they made it a priority to revise the jetting for more accurate damper control. The engineers also increased the adjustment range. Every click in the adjustment range now has a very profound effect on damping force and each click is very audible and distinct. We responded to our clients' comments regarding the lack of audible distinction in the clicking mechanism. Our desire is to constantly refine our products using the valuable feedback from our clients, so we have addressed this issue with our Generation 4 shocks.
Stronger Piston Shafts
The data we have compiled through our racing program has been thoroughly implemented in our new Generation 4 Series. The delicate science behind the strength of piston shafts can be difficult to perfect. If the shaft is too hard, it will be brittle and break easily, but if the shaft is too soft it will bend too easily. Through extensive R&D we were able to achieve an optimal balance between shaft hardness and malleability in the Generation 4 Series to ensure peak safety and performance.
Lower Friction Shaft Seals
The new Generation 4 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.
Improved Shaft Cap Design
Our new shaft caps utilize a twin O-ring design. Furthermore we have upgraded our rubber O-rings to Viton O-rings. The new Viton O-rings are made of a synthetic rubber compound which provides a superior tensile strength and a wider range of operating temperatures. This new design provides a superior seal preventing potential leaks from developing.
Utilizing our engineers' in-house design software we were able to revamp our whole line of suspension in the Generation 4 Series. We reinforced brackets and mounting points for more rigidity and strength.
Brake Line Brackets
Now most models will have OEM brake line tabs welded to the lower mounts. This provides the end user with a clean and safe install solution.
Digressive & Ultra Digressive Pistons
To ensure superior ride quality and driver control, the digressive piston technology on our 500 and 510 series has been carried over to the Generation 4 Series as well. All Generation 4 shock absorbers will continue to utilize our digressive piston technology on our 500 series models and ultra digressive piston technology on our 510 series models. Digressive piston technology allows for massive amounts of low speed rebound force that translates driver inputs into razor sharp control. Furthermore, the rebound force "blows off" to provide the driver with a supple and compliant ride while maintaining superior mechanical grip over rough surfaces.
Dyno-tuned and TestedOur commitment to providing the best shock absorber in the market has not changed with the Generation 4 Series. EVERY shock absorber is still dyno-tested at our facility. We do not spot check our shocks like some other manufacturers. Once your shock absorber is built it is tested and matched. We refuse to treat our shocks with a “one size fits all” mentality. Our philosophy is simple: to provide our clients with a high quality, affordable, and personalized suspension solution.
