EV1010-1075 66 tooth ring gear replacement weld on

For the guys running the classic Shovelheads and early Evos, this 66-tooth ring gear from Evolution Industries is a solid choice for a primary rebuild. This is a weld-on replacement gear, meaning it is intended for those who are comfortable with a torch or have a shop handy to seat it properly on the clutch basket. It fits 1965 to early 1984 Big Twin models, covering a wide range of four-speed and early five-speed bikes. Because it is a weld-on unit, it provides a permanent, rock-solid connection that will not slip or chatter under load. It is a great way to restore the starting performance of an older machine without replacing the entire basket.
