1.160 Smaller bore and Sport Compact engines with higher cylinder pressure require better sealing power than most other applications. Our CPN ring sets are designed to meet those high demands. Compatible with today’s new cylinder materials, such as Nikasil or Alusil, these high strenght, low tension ring sets offer optimum sealing with minimum drag. 1.335

H The nitriding ensures extended life and protection under extreme conditions. 3.18 TOP RING The top ring is a steel compression ring that has been gas nitrided so that it is compatible with Nikasil and cast iron bores. This scuff resistant gas nitrided ring allows it to operate at maximum efficiency without blemishing up the bore.

SECOND RING The second ring is a cast iron with a taper hook groove face. The THG ring acts as a wiper and pushes the oil back away from combustion. This type of ring allows you to run a lower tension oil ring.

CAP SECTION C-C expander. Because of the miniflex vent design; there is less friction on the cylinder wall, which increases the performance and efficiency of the engine. 2nd land Pin OIL RING The oil ring is made up of two gas nitride rails with a low-tension
