Despite the slightly confusing picture, this is the one-piece rear crankshaft seal kit. It is the improved design compared to the original two-piece, and it was recommended by my mechanic. I had it shipped directly to him, so I never saw the part for myself. However, my mechanic said he had no problems with any of the components(all ordered from Partsgeek), and everything has been functioning great. I drive delivery, so I put a lot of stress on my clutch. I could not be happier with the price points found on Partsgeek, and based on performance, I know I did not sacrifice quality. And, as always, Partsgeek delivered my parts faster than I could have imagined through their base level shipping service. I'll be coming back to this site for all my parts, and I would recommend this crankshaft seal kit to anyone looking to replace theirs.
