Q:Are the rings pre gapped ?
Wade B.
A:BEST ANSWERHi Wade, I am pleased to assist you. The piston ring set does come pre-gapped. However, the end gap often needs to be checked and adjusted during installation to ensure proper fitment for your specific engine. Check your engine’s service manual for the recommended piston ring end gap specifications. These vary based on the engine type, application, and intended use (e.g., naturally aspirated vs. forced induction). Always double-check the manufacturer’s recommendations and measure each ring for each cylinder, as tolerances may vary. If your vehicle information matches this product, you can use the link below to order while the part is in stock. Your order will come with a 30-day post-purchase price match guarantee. I hope this helps, and enjoy shopping! https://www.carparts.com/piston-ring-set/dnj/dnjpr4245?can=CPGG4850_CSQA_20241203 Show less
