The YBB Rebuild Kit is something you will definitely need at some point in time, depending on how much you ride that YBB bike of yours. The slider is the part that wears out. The rebuild kit comes complete with a new slider, a rubber wiper and the aluminum cup the slider fits into. Replacement spring sold separately & includes elastomer. You will need to remove the slider and/or spring for sizing confirmation. We have provided instructions here with an image of how to measure those parts. We do not have record of these dimensions in our Serial Number archives. Please disassemble and measure to confirm lengths. This is a NON-REFUNDABLE item. REBUILD INSTRUCTIONS TORQUE SPECS
