Technical Details and Specifications

The E-989K piston ring set features a precise 93.00 mm bore diameter compatible with Chevrolet Canyon, GMC Colorado, and Hummer H3 models. The top ring utilizes a steel base with a molybdenum coating to reduce friction and wear, while the second ring is made from grey iron with a phosphate coating to resist corrosion and maintain sealing integrity. The reverse torsional face design on the second ring helps maintain ring tension and reduces blow-by gases. The oil ring is a 3-piece flex vent design, providing efficient oil scraping and control to prevent excessive oil consumption. Ring groove widths are optimized at 1.2 mm for the top ring, 1.5 mm for the second ring, and 2.5 mm for the oil ring, ensuring proper seating and performance.
