What is the purpose of the different ring widths (1.2mm, 1.2mm, 2.8mm)?

The top and second rings (1.2mm each) are designed for optimal sealing in the cylinder bore, while the wider 2.8mm oil ring is responsible for scraping excess oil from the cylinder walls. These specific dimensions are chosen for particular engine designs to ensure proper function.

Are these rings suitable for all engine rebuilds?

This ring set is specifically designed for an 86.5mm bore size and is intended for the vehicle fitments listed. Always confirm your piston bore size and vehicle compatibility before purchasing to ensure a proper fit for your engine rebuild.

What should I know about installation?

Proper installation is critical for performance and engine longevity. Always refer to your vehicle's specific service manual for correct piston ring orientation, gap settings, and installation procedures. Ensure the cylinder walls are clean and properly honed.
