ACL Nissan L20/L24/L28 1998cc/2393cc/2753cc 6cyl 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 L20, L24, or L28 engine is one of their staples. These bearings are designed to handle the demands of performance engines, offering a solid option for rebuilds where reliability and durability are key. They are precision-machined to meet strict tolerances, ensuring a proper fit and function within the engine block. This set is specifically sized at 0.025 inches undersize, which is crucial for engines that have had their crankshaft journals ground down during a previous rebuild or repair.

When you're rebuilding an engine, especially one that's seen a lot of miles or is being built for more power, the main bearings are critical. They support the crankshaft and need to maintain consistent oil clearance under load. ACL uses well-built materials and advanced manufacturing techniques to create bearings that resist fatigue and wear. This particular set is designed for the 1998cc (L20), 2393cc (L24), and 2753cc (L28) inline-six engines found in various Nissan vehicles, including the 240Z, 260Z, 280Z, 280ZX, 810, and Maxima models from the 1970s and early 1980s. The 0.025 inch undersize means they are intended to be used with a crankshaft that has been machined down by that amount.

For a successful engine rebuild, it's important to ensure your crankshaft journals are properly measured and cleaned before installing these bearings. Always refer to the manufacturer's service manual for the correct installation procedures and torque specifications. Using the correct oil clearance is vital for engine longevity and performance, so double-check your measurements.
