The Dal Soggio 1P.KIT RAY 2016 RAY Kit<\/strong> is a high-performance internal suspension upgrade developed specifically for 2016 WP 4CS front forks<\/strong>.<\/p>\n

The RAY system is designed to significantly change the way the original WP 4CS hydraulic system operates rather than simply modifying the stock shim settings.<\/p>\n

Once installed, the kit reorganizes the internal damping functions by positioning compression control in the lower section<\/strong> and rebound control in the upper section of each fork leg<\/strong>.<\/p>\n

This revised hydraulic layout allows both fork legs to contribute more effectively to damping control and changes the way oil flows through the WP 4CS system.<\/p>\n

One of the main characteristics of the RAY concept is the increase in hydraulic flow through the shim stacks. According to Dal Soggio, the system doubles shim oil flow<\/strong>, helping the fork react more naturally and with reduced internal friction.<\/p>\n

The objective is to improve sensitivity, damping consistency, rider feedback, comfort, and front-end control while retaining the original WP 4CS fork assembly.<\/p>\n

Dal Soggio developed the RAY Kit not only for experienced and professional riders, but also for riders looking to obtain a more natural and controlled feel from the WP 4CS platform.<\/p>\n

    Kit Contents<\/h3>\n

    The RAY Kit<\/strong> includes:<\/p>\n

      \n
    • 2 assembled compression units<\/strong><\/li>\n
    • 2 pins with rebound calibration<\/strong><\/li>\n
    • 2 compression clickers for installation on the upper caps<\/strong><\/li>\n
    • 2 adjusters to increase spring preload<\/strong><\/li>\n<\/ul>\n

      These components are designed to operate together as a complete hydraulic conversion for the WP 4CS system.<\/p>\n

      <\/h3>\n

      <\/h3>\n

      How the RAY Kit Works<\/h3>\n

      The RAY Kit changes the original WP 4CS damping architecture by separating the two main hydraulic functions within each fork leg.<\/p>\n

      After installation:<\/p>\n

        \n
      • compression damping operates in the lower section of each leg;<\/li>\n
      • rebound damping operates in the upper section of each leg;<\/li>\n
      • hydraulic oil flow through the shim system is increased;<\/li>\n
      • both fork legs participate more effectively in suspension control.<\/li>\n<\/ul>\n

        Dal Soggio states that this arrangement doubles oil flow through the shim system<\/strong>, helping the fork operate more freely and with improved feedback.<\/p>\n

        The revised architecture is designed to make suspension behavior more natural while reducing internal resistance and improving damping control.<\/p>\n

        <\/h3>\n

        <\/h3>\n

        Suspension Behavior<\/h3>\n

        The RAY system is designed to improve several aspects of WP 4CS fork behavior, including:<\/p>\n

          \n
        • initial sensitivity;<\/li>\n
        • hydraulic damping consistency;<\/li>\n
        • front-wheel feedback;<\/li>\n
        • comfort over repeated impacts;<\/li>\n
        • control during larger suspension movements;<\/li>\n
        • overall confidence and predictability.<\/li>\n<\/ul>\n

          Rather than replacing the complete fork, the RAY Kit modifies the internal hydraulic system while retaining the original WP 4CS structure.<\/p>\n

          <\/h3>\n

          <\/h3>\n

          Materials and Construction<\/h3>\n

          Dal Soggio specifies the use of ERGAL 7075 T6<\/strong> for RAY Kit components, with some parts manufactured using Teflon<\/strong>.<\/p>\n

          The use of these materials is intended to provide a combination of low weight, mechanical strength, low-friction operation, and durability within the suspension environment.<\/p>\n

          <\/h3>\n

          <\/h3>\n

          Application & Compatibility<\/h3>\n

          The 1P.KIT RAY 2016<\/strong> is intended specifically for WP 4CS front forks in the 2016 configuration<\/strong>.<\/p>\n

          Dal Soggio distinguishes three RAY versions:<\/p>\n

            \n
          • RAY Kit 2013-2015;<\/li>\n
          • RAY Kit 2016;<\/li>\n
          • RAY Kit 2016 MX \/ Cross.<\/li>\n<\/ul>\n

            Because these versions correspond to different WP 4CS configurations, the correct kit must be selected according to the exact fork specification.<\/p>\n

            <\/h3>\n

            <\/h3>\n

            Installation Note<\/h3>\n

            Installation requires complete disassembly and servicing of both WP 4CS fork legs, followed by installation of the RAY hydraulic components.<\/p>\n

            Correct assembly, rebound calibration, compression-clicker installation, spring preload adjustment, oil filling, bleeding, and final suspension setup are essential for proper operation.<\/p>\n

            Dal Soggio recommends installation and setup by a qualified suspension technician or authorized specialist<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
