Comes with everything shown. 2 piston kits to complete 1 engine. We also have a 0.25mm oversize version of this kit.

Note: Be very careful when installing the cylinder over new pistons, it's helpful to have the proper tool to keep the rings compressed as you lower the cylinder over the pistons. Try to use only plastic tipped tools to prevent from scratching aluminum surfaces.
