Decent upgrade to the plastic savage s-25 diff cups. screws provided are a bit short, recommend reusing yours. Otherwise its a good match.
Great customer support. When I went to upgrade my old s-25 first generationplastic savage diff cases to these I noticed a significant casting imperfection on the crown gear to diff case mating surface. would not hold diff fluid as is. seller credited me appropriately for this flaw, and was very easy to work with, big thumbs up. may attempt to fix with JB weld / or a moto seal product.
not original hpi. Quality seems good. But need to install first and run
