What is the advantage of compensated ring grooves?

Compensated ring grooves help ensure the piston rings are properly loaded. This is important for effective oil control, preventing oil from entering the combustion chamber, and reducing blow-by.

Are the piston rings included and pre-installed?

Yes, this set comes with the piston rings already mounted on the pistons. It also includes the necessary piston pins and clips, making it a ready-to-install solution for your engine rebuild.

What does the 0.25MM undersize mean for my engine?

The 0.25MM undersize indicates that these pistons are slightly smaller than the standard bore size. This is typically used when a cylinder bore has been honed or machined to a specific oversize to ensure a proper fit and clearance within the cylinder.
