CP Piston & Ring Set for 4G63 2G-Bore (85.5rmm)-Size (+.5) CR 8.5 SINGLE PISTON

CP Pistons is well-known for making strong internal engine components, and this forged piston set is a great example of their work. This specific set is built for the 4G63 engine, featuring a 2nd generation bore size of 85.5mm and a +.5mm oversize. It comes with a compression ratio of 8.5:1, making it a solid choice for builds looking for reliable performance.

These pistons are forged, which means they start as a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, able to handle higher cylinder pressures and temperatures. The +.5mm oversize is important to note; it means these are intended to replace pistons that have been bored out to that specific size, ensuring a proper fit in a rebuilt or modified engine block. This set includes the rings needed for installation.

Please be aware that this part is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
