What is the primary purpose of these compression rings?

These top compression rings are the first seal in the combustion chamber. Their main job is to prevent combustion gases from escaping past the piston into the crankcase, which is known as blow-by. This ensures efficient power transfer and helps maintain engine oil integrity.

What does 'cast claimer' refer to in the product description?

'Cast claimer' refers to the material and design of the ring. It indicates the rings are made from cast iron and are designed to be a reliable, standard replacement for many engine applications, particularly in rebuilt engines where a solid seal is needed.

Why are these rings not CARB approved?

Some engine components are subject to emissions regulations, such as those set by the California Air Resources Board (CARB). This particular set of rings does not meet CARB standards, which means they cannot be legally sold or shipped to California.
