This is a replacement Picco Boost .28 Piston and Sleeve Set, and is intended for use with the Picco Boost 5TR .28 nitro engine, as well as the Picco P3 .28 nitro engine. This set is not intended for use with the Picco .28 Pull-Start version. The pull-start Piston/Sleeve set is part PIC1371.
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.
