Engine Pro
has announced the latest addition to its line of black nitrided
high-performance engine parts, Nitro Black race rings, developed to
offer advanced features usually found in more expensive performance
race rings. The two top rings and oil rails are made of black, gas
nitride-hardened stainless steel, creating a smooth surface for maximum
sealing. The faces of the top ring and oil rails are ceramic PVD-coated
and have very low coefficients of friction. They also provide superior
scuff- and heat-resistance and excellent seating. The second ring is a
Napier design for optimum durability and oil scraping ability under the
most severe performance conditions. Nitro Black rings are especially
well-suited for turbocharged, supercharged and nitrous engines.
