Picco Boost 5TR .21 Piston, Sleeve & Head Button Set
This is a replacement Picco Boost Piston, Sleeve and Head Button Set, and is intended for use with the Picco Boost 5TR 2012 .21 nitro engine. The head button is installed between the engine case and the cooling head.
NOTE: You will need to detach the old connecting rod and re-attach it to the new piston during replacement. We recommend that when you replace the piston/sleeve on any engine, you also change the connecting rod and wrist pin clips.
