Motion Pro is dedicated to producing the most versatile, unique and durable products for professional and home use. Motion Pro tools are designed to be simple to use, yet durable enough to withstand the harshest conditions. One of their goals is to offer tools of convenience. Do it right the first time with Motion Pro Tools. Designed to remove and install the clip on Harley-Davidson® collapsible push rod tubes. Flat portion of tool fits under the cylinder head while cupped end fits over the bell in the tube and then compresses the spring allowing for easy access to the spring cap retainer. No more cut knuckles and scratched engine parts from using a screwdriver between the fins. New improved design with shoulder bolt pivot for smoothness and durability. Note: For Twin Cam and earlier models.
