Kit includes Pistons/Cylinders/Rings/Pins/Clips/O-rings - Set of 4 - We recommend these German Piston/Cylinder kits. We have found that the piston top to piston pin hole distance is different on Brazilian pistons and lowers the compression. We do not stock them. Note - if you place an order on the site you are ordering a German original spec set. Price has risen considerably this year. We do like this set best but now understand that the price has become a bit harder to swallow.
