This is the better quality. Aftermarket 372 XP crankcase with high quality Hyway Seals...We know there are cheaper ones to be found out there but oftentimes on those the quality is lacking. The cheaper ones tend to have thinner metal, holes that are untapped or improperly tapped and the dimensions do not line up to spec. We've been using these crankcases for years with great success. Not all aftermarket parts are created equally and this is certainly the case (no pun intended) here
