Alright, let’s talk about the Fortune Auto Generation 6 Internal Floating Piston. If you’re looking for a serious upgrade for your ride, this is it. They’ve really knocked it out of the park with this one. First off, it’s lighter than previous versions, and that low-drag Teflon band? Game changer. It cuts down on stiction big time, which means your damper responds to shocks way quicker. Less waiting around for things to settle down, and more time enjoying the drive.

Now, let’s get into the nitty-gritty. The Fortune Auto 500 series damper shaft seals have been revamped. They’re now 40% less drag than what you’d find in older models. What does that mean for you? Better control over those driver inputs and less hysteresis. The new seals are made from a special Buna rubber compound, which strikes a solid balance between reliability and performance. Since the shaft seal is crucial for the shock’s performance, having a stronger seal means you’re getting better quality overall.

Shims, those little deflection disks that cover the piston port holes, play a huge role here. They control fluid flow, which in turn generates the force in the damper. If you’re into tuning, you’ll appreciate the ability to re-valve your shock using various shims. Just remember, tiny differences in shim thickness can shift the damper’s force profile by as much as 25%. Fortune Auto uses high-grade Sandvik steel for their shims, so you know they’re precise and consistent.

Speaking of durability, the bright dip anodizing process gives the 6061 forged aluminum parts a slick, shiny surface that protects against corrosion and oxidation. Your parts will look sharp for years to come, even after some serious use. Plus, the revised jetting and expanded adjustment range mean you’ve got more control over the damper settings. Each click in the adjustment range is noticeable, so you can really fine-tune your ride.

Now, let’s chat about the piston shafts. Fortune Auto has done their homework here. They’ve struck an optimal balance between hardness and malleability, which is crucial for safety and performance. And they didn’t stop there; the brackets and mounting points have been reinforced for added strength. You’ll even find OEM brake line tabs welded directly to the lower mounts for a cleaner, safer installation. It’s the little things that make a big difference.

The digressive piston technology is where the magic happens. It gives you tons of low-speed force, translating your inputs into precise control. But don’t worry, it still provides a smooth ride over rough surfaces. You get the best of both worlds here.
