  • Factory parts
O.e.m replacement parts for a perfect fit.
Reviewed in the United States 🇺🇸 on October 17, 2022 by jeff altman

  • 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.

Item came with extensive casting slag, I had to file and sand all the teeth to allow smooth operation

  • Must install shim kit to on one side of differential.
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.

  • As described
Definitely need to shim these or they strip easily, then again a run 6s on 10th scale

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