  • Reducing oil consumption caused by ring wear
  • Correcting blow-by from tired piston rings
  • Replacing rings during a full engine rebuild
  • Matching factory-style bore and groove specifications

Installation notes and tips

Verify bore size, groove width, and cylinder count before installation. Clean piston ring grooves thoroughly and inspect cylinder walls for taper, scoring, or out-of-round conditions. Follow the engine builder’s ring end-gap and break-in procedures for the specific Toyota Tacoma, Toyota Tundra, or Toyota 4Runner engine being serviced.
