ModMax OEM Replacement Pistons are a great choice for a rebuild or an upgrade to change compression for street and mild race applicatons. These pistons are precision cast from High Silicon Hypereutectic aluminum alloys to exceed OEM specs. The special alloy allows for great heat transfer, low expansion for tight sealing, and even material distribution through the alloy to eliminate weak spots. They will fit all 4.6 SOHC or DOHC 2V or 4V engines (NOT 3V), or all 5.4 2V, 3V, or 4V engines. Any of our standard replacement ring sets or upgraded rings will fit these pistons. Whether you have press fit or bushed rods these pistons are equipped with retaining locks for the pins so they can work for either rod application.
