Your cart is empty.The ring gear has teeth which engage with the starter motor allowing the engine to crank over and start. Repeated engagement with the starter results in worn or broken ring gear teeth. Once this is diagnosed, the ring gear must be replaced. ATP ring gears are designed to fit and function just like the original part to ensure durability and long life.

Installation went ok, didn't take a lot to press onto the flywheel, after finishing installing engine, trying to start the ring gear spun on flywheel. Ended up drilling and pinning gear to flywheel.

I spent $500 to get my mechanic to install this. 1 week later - after only starting my Jeep 5 times, it was severely ground down and would no longer start at all. VERY dissatisfied with the part and with Amazon that only compensated me with $30 and the cost of the part. Pathetic!

Purchased to replace a heavily worn ring gear on a 1983 CJ-5 with a 258. Handed this off to my machinist to install as part of having the flywheel resurfaced. Looks and fits great. I hope to get 34 years out this one too, we'll see.
