This is a replacement Werks Racing 7-Port Piston/Sleeve Set, and is intended for use with the Werks B7 Pro .21 engine. The piston has been lightened and domed for increased compression. While the sleeve features revised timing and a new smaller bore (long stroke design!), with tear dropped transfer ports & chamfered lower sleeve for improved fuel flow.
NOTE: You will need to detach the old connecting rod and re-attach it to the new piston/sleeve during replacement. We recommend that when you replace the piston/sleeve on any engine, you also change the connecting rod and wrist pin clips.
