What is the CT-1 coating?

The CT-1 coating is a dry film lubricant applied to the bearings. It helps reduce friction and wear, especially during engine break-in and under high-performance use.

Do these bearings come with the necessary hardware?

This listing is for the main bearing set only. It includes the bearings themselves. You will need to source any required installation hardware separately.

What does 'extra oil clearance' mean for my engine?

Extra oil clearance means there is a slightly larger gap between the bearing and the crankshaft. This allows for increased oil flow, which can help with cooling and lubrication, particularly in engines that are driven hard.
