Fit's all 90-05 Miata:

  • Part Number: CF-30/16LC
  • Diameter: 30mm
  • Length: 26mm
  • Post Thickness: 16mm to be used with 5.5mm lash cap on the post
Supertech Bucket Lifters Feature:
  • Made of Aerospace certified Chrome-Molybdenum-Vanadium alloys. This is a much stronger material than the alloys used in extruded lifters.
  • Completely CNC machined from heat treated billet provides only the necessary and calculated thickness of the walls with very special shapes, providing better rigidity with an important reduction in weight.
  • The lifters are fully Nitrided and polished to harden the surface for low wear. Higher cam lifts and rpms will submit conventional lifters to an important wear.
  • Surface is carefully finished by grinding it to a much lower surface roughness for lower friction with the cams, cylinder head bore, providing longer durability.
