All of LC Engineering's forged pistons now come standard with gas nitride ring sets. These rings were developed originally for boosted applications (turbochargers and superchargers). However, when applied to our 22R/RE engines we found this new ring allows us to run a smaller ring to reduce any extra horsepower loss due to excess friction and still allow proper ring sealing.
