Front cartridge pair for Harley-Davidson Softail applications. Makes it easy to up-grade your factory internal fork assemblies. These replacement style cartridges are a perfect fit. Each cartridge has 2 chambers for lift, and 2 for rebound in axial alignment. This allows us to increase piston surface area, thus reducing air pressure required to lift. To dampen compression during hard braking we have add a booster spring. The result is a much smoother, and consistent ride and increased handling. Each kit is specifically designed to fit your bike without modification and exceeds all manufacture specifications.
One inch stainless steel fork extensions are provided with a side port for the air inlet. Therefore, the air lines can be hidden under the upper triple tree and also be hidden by the stock fork covers.
