For use on Big Twins 1954 thru early 1981, 1 5/16" socket with 1/2" drive
Look no further for the best flywheel rebuilding sockets available. Zodiac offers these low-profile flywheel sockets, which are just long enough to give 100% nut to sprocket contact and 100% drive end contact. Machined flat at the nut receiving end to eliminate rounding off the nut and greatly reducing the risk of bodily injury. These sockets are machined from solid steel 4130 chromium-molybdenum and heat treated to give a lifetime of service. Available in various models for use on Big Twin models from 1954 to present and Sportster models from 1981 to present.
