This is a replacement O.S. B2101 & B2102 Speed Complete Piston, Sleeve and Rod Assembly. This assembly not only includes 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.
