GTO and 3000GT 6G72 ACL Fully Coated Hard Race Complete Engine Bearing Set 0.25mm Over Size

We now offer a Hard Race fully COATED ACL engine bearings for the GTO & 3000GT DOHC 6G72 engine. These are the same ACL Bearings we have been selling and running for the last couple of years, but these have had a special coating added to them to help with longevity and cold starts on both Mains and big end bearings

The biggest benefit of coated bearings is preventing damage during cold starts and events where oil starvation is evident. Starting your car is almost the worst thing you can do as the oil has had time to drain out of the engine back into the pan. The oil is cold and thicker and takes time to get circulated throughout the engine, including to the crank bearings. The added dry film lubricant coating acts as a barrier between the bearing surface and the crank journal. Other benefits are less friction and longer bearing and crank journal life. The special coating also has moly and other ingredients that retain oil rather than repell it.

The coating is a patented process whereby the bearing is purified (degreased and degassed), and the coating is bonded to the bearing babbitt layer without removing babbitt layer. The coating is cured onto the surface under temperatures of around 300 degrees F. Each shell is inspected before and after the coating process to ensure consistency. The coating thickness is about 0.0002" - 0.0003" per shell.

This coating process was developed for and is used in race engines, and applied to street and daily-use cars to help yield more durable engines

NOTE: Both the MAIN bearings and the Big End bearings are coated in this kit.
