Our aftermarket International Harvester tractor parts are designed to replace the original IH Parts and this steering wheel is no exception. Our 806 International steering wheel (of course it fits many other models too!) has a hub with splines half way thru, not all the way thru. This tractor steering wheel contains 36 splines. This replaces the original IH Parts # 385156R1 and is just like the original. It is made of all new material including the steel spokes. Our tractor steering wheel measures 16” in diameter and has a 7/8” shaft. The 3 spokes are covered to the center just like the factory original on an 806 International and many other models.
