Product Details
This is a Mahle OE Performance Steel Napier 2nd Ring Set, part number 3021371. These rings are designed to replace the stock piston rings in many engines, helping to restore proper compression and oil control. The Napier hook design on the second ring is a common feature that aids in oil scraping and helps prevent blow-by.
Mahle is a well-known name in engine components, and this set is made with steel for durability. The specific dimensions, 3.922 inches in bore size with a 1.0mm ring thickness and a 0.136-inch groove depth, are critical for proper fitment and sealing within the piston groove. Ensuring you have the correct ring set is key to a healthy engine rebuild, as it directly impacts compression, oil consumption, and overall performance.
