ACL Race Main Bearing Set — 68-74 Nissan L16E/L18E 1595cc/1770cc 4cyl — 0.025mm Extra Clearance

Crankshaft main bearing set — Race Series. Supports the crankshaft in the block and carries the main load of every combustion event.

Application: 68-74 Nissan L16E/L18E 1595cc/1770cc 4cyl.

ACL Race Series. Heavy-duty performance bearings, identified by the H in the part number. Designed for high-load and boosted applications.

0.025mm extra clearance — not an undersize. This set fits a standard-size journal and simply runs 0.025mm (0.001") more oil clearance, for a shaft with light wear or a build wanting a looser clearance.

Do not confuse 0.025mm with 0.25mm. They are ten times apart. If your crank has been reground, you need the 0.25mm Undersize set, not this one.

ACL part number: 5M1172H-.025
