What does the 'GL TOP' designation mean for these piston rings?

The 'GL TOP' designation typically refers to a specific type of coating or design for the top compression ring. This often relates to improved wear resistance and performance under high temperatures and pressures, common in performance engine builds.

What is the significance of the .043, .043, and 3/16 ring sizes?

These numbers refer to the thickness of the piston rings. The first two are the compression rings (top and second), and the third is the oil control ring. This specific sizing is crucial for matching the grooves on your pistons and ensuring proper sealing and oil control within the cylinder.

Why are these rings not CARB approved?

CARB (California Air Resources Board) approval is required for certain engine parts sold in California to ensure they meet emissions standards. Parts that are not CARB approved, like these rings, cannot be legally shipped to California due to these regulations.
