SXR 800 Adjustable Handle Pole Spring Tensioner Kit

Thank you for considering R & D Performance Products for your high performance needs! The R & D adjustable handle pole spring preloader is another industry first! The R & D adjustable spring preloader was designed to work with any after market handle pole design or weight. The adjustability in spring tension to have a lighter or heavier handle pole weight is something that top pros desire to change, and have been changing pending conditions! For example, for many years, multi-time National and World Champion Jeff Jacobs would run heavier spring tension (lighter handle pole) in flat water or slalom conditions and run lighter spring tension (heavier handle pole) in surf conditions. The R & D adjustable spring tensioner allows you to adjust and tune to find the best tension for you!
