FLEXCO Flex-Lifter Retrofit Stop Kit Operating instructions

  • Hello! I've reviewed the Flex-Lifter Retrofit Stop Kit installation instructions and understand it details how to properly install the provided stop kit, which include a stop tube, dust guard, spring, countersunk screw, and nylock nut. This kit is needed for Flex-Lifters within certain serial number ranges. I'm ready to assist you with any questions you may have about the installation process or the components.
  • What should I do before starting the installation?
    What do I need to do with the old dust cover?
    Which way should the Dust Guard be placed in the Stop Tube?
