What This Piston Helps Address

• Worn or damaged original piston surfaces during engine overhaul
• Compression loss caused by piston wear or ring land damage
• Incorrect piston-to-bore fit in rebuild work
• Combustion chamber service requiring the specified bowl piston profile
• Restoration of proper ring groove dimensions during cylinder block repair

Installation Notes and Tips

Verify cylinder bore diameter, compression height, piston pin diameter, and ring thickness before installation. Match the piston to the engine’s original specification and inspect the cylinder block, rings, and pin fit during assembly. Assembly lubricant is not included, so use the lubricant specified by the engine builder or service procedure.
