    • OEM part. WHY NO GASKET??????
Parts are fine but this assembly requires a gasket between these two parts and it should be replaced not reused. Why doesthis assembly not include a gasket??? Just a pain to buy separate.

They work fine as long as you purchase this washer/shim set. Put shim on so that it pushes differential gears closer to the gears on input shaft. I went threw a few before I seen someone putting shims in. Now I have not stripped another one. It helps turning punch down also.

    • Brittle plastic that breaks on the first use
Gears broke the first use. Very week plastics. Not worth the money.
