This is a replacement O.S. Speed 21XZ-B Spec II Complete Piston/Sleeve/Rod Assembly. This includes not only the piston and sleeve, but also the connecting rod, wrist pin and wrist pin clips. In fact the rod is already pre-assembled for you, so you can simply install it in the engine and forget about the hassle of removing wrist pin clips to install a new rod!
