81,5mm performance piston rings for 4 cylinder engines - 1,5 / 1,5 / 2,0mm thickness - Set
Piston rings 81,5mm set
Contains 01 complete set for‚ 4 cylinder engine.
Compatible with pistons with 1.5mm / 1.5mm and 2mm channels tickness.
Ring thickness:
1st ring 1.5mm - Made of carbon steel, which is 35% more resistant than cast iron and on average 30% lighter. With DLC (Diamond-Like Carbon) treatment, which is the application of carbon particles, whose physical and chemical properties are very close to those of the diamond, providing greater resistance to the material and reducing the friction of the surface, which significantly reduces friction when working against other surfaces.
2nd ring 1.5mm - Made of cast iron.
3rd ring 2.0mm - Manufactured in 3 pieces, which guarantees easy maintenance, better stability in the control of the oil film and improves the oil removal through the piston lubrication holes, as it has a better area for displacing this oil.
