JUN Machine Shop has added a New series to JUN Piston Kit as W-Series, and now it is on sale. And, we changed name of Super Piston Kit into C-Series, and also Hyper Piston Kit into R-Series.

The new W-Series piston kit expanded by cooperation of Wössner GmbH in Germany. This W series is an excellent product in the cost performance. It is an excellent piston in the durability because it is the design which has a few loads that heat efficiency was put on the emphasis. We made many types of vehicle and bore size. A choice in your needs will be able to be done.
