What I've noticed is usually crankshafts under $99 doesn't have a hole drilled on the small end to lubricate the bearing. $99 and over crankshafts do. The ones without the hole drilled to me is more for stockish setups that don't see hi rpms or get beat on. So I would say if you're going for a mild build, go for it. If you're trying to blast hard don't do it........
