The Kyosho 74032-06 piston pin secures the piston to the small end of the connecting rod in KE25SP engines. Its main function is to preserve piston alignment and enable efficient transfer of reciprocating force.
Made to tight tolerances, the pin helps avoid side loading and uneven wear on the piston skirt and bore. Keeping this component in good condition supports longer engine life.
As a direct replacement for KE25SP models, the pin installs with standard engine service procedures and lets hobbyists restore correct internal geometry without modifications.
