About this part

Product Details

ACL has been making engine bearings for decades, and this crankshaft main bearing set for your 1991-1993 Nissan NX is one of their staples. These bearings are crucial for supporting the rotating crankshaft within the engine block, reducing friction and wear. This specific set is designed for the 1998cc SR20DE and SR20DET engines found in those NX models.

This set is an undersize bearing, meaning it's 0.75mm larger in diameter than standard. This is typically used when the crankshaft journals have been machined down to correct for wear or damage. Using the correct undersize bearing ensures proper oil clearance and a snug fit for the crankshaft, which is essential for engine health and longevity. ACL is known for well-built engine components, and these bearings are made to handle the demands of performance engines.
