Are the piston rings included with this set?

Yes, this set comes with piston rings pre-mounted on each piston. It also includes the necessary wrist pins and clips for a complete engine build.

What does the .040 undersize mean for these pistons?

The .040 undersize indicates that these pistons are slightly smaller than the standard bore size. This is typically used when a cylinder bore has been machined to a larger diameter during an engine rebuild to account for wear.

Can these pistons be shipped to California?

No, this piston set is not CARB approved and cannot be shipped to California due to emissions regulations.
