1 3/8” Horstman go kart racing axle clutch. Condition is "Used". This came on a kart I bought and I was going to use it for a project but I have since changed my mind. I don’t know anything about it other than I drained the oil out for Shipping and it looked pretty good. Please realize this item is used so it is far from perfect. Please examine the photos closely as I do not accept returns Thank you
