ACL 68-74 Nissan L16E/L18E 1595cc/1770cc 4cyl 0.025 Oversized High Performance Main Bearing Set

ACL has been making engine bearings for decades, and this high-performance main bearing set for your Nissan 510 is one of their staples. If you're rebuilding your L16E or L18E engine, these bearings are a solid choice to ensure proper oil clearance and support for your crankshaft. They are specifically sized at 0.025 inches undersize, which is crucial if your crankshaft journals have been machined down during a rebuild to correct wear or damage.

These bearings are built with a multi-layer material that's designed to handle the demands of performance engines. The goal here is to provide a strong, reliable foundation for your engine's rotating assembly. When you're installing these, pay close attention to your engine's specific oil clearance specifications, as these bearings are meant to be used with a machined crankshaft. Proper installation and torque are key to getting the most out of these components.

This set is designed to fit a range of Nissan L-series engines, including those found in the 510, 521 Pickup, 610, 620 Pickup, and 710 models from the late 60s through the mid-70s. Make sure to verify your engine code (L16E or L18E) and the specific year range for your vehicle to ensure compatibility.
