High-quality ACL race rod bearings for 1990-05 Miata engines. They'll take a huge amount of abuse and are viewed as one of the industry standards.

Available in stock or 0.25mm (0.010") oversize for machined cranks.* It's always best to check the size you need rather than make assumptions.  

Included in our engine rebuild kits.

  • Stock = 44.940-44.956 / 1.7693-1.7699
  • .25 / .01 = 44.690-44.706 / 1.7595-1.7600
