ACL 89-02 Nissan 4 2389cc KA24E/DE +.75 Oversized Main Bearing Set

Already running a rebuilt or performance engine in your 1990 Nissan Axxess? This set of main bearings from ACL is the next piece of the puzzle. These bearings are crucial for supporting the crankshaft and ensuring it spins smoothly within the engine block. When you're rebuilding or upgrading your KA24E or KA24DE engine, using the right bearings is key to long-term reliability and performance.

This particular set is +.75mm oversized, meaning it's designed for a crankshaft that has been machined down by 0.75mm. This is common when a crankshaft has been worn or damaged and needs to be reconditioned to factory specifications, or when building a performance engine where specific clearances are desired. ACL is known for making well-built engine components, and these bearings are made to precise tolerances to help maintain proper oil clearance and reduce friction.

When installing these bearings, make sure to follow the manufacturer's recommended torque specifications and oil clearance checks. Using the correct installation procedures will ensure these bearings perform as intended and contribute to a healthy, long-lasting engine build.
