Product Description

The Clevite MS-1949H main bearing set is engineered for standard rebuilds and maintenance of 2001-2003 Nissan Altima, Frontier, and Xterra models equipped with the 2.4L KA24DE engine. These bearings are manufactured with a tri-metal construction, offering enhanced durability and performance over standard bi-metal bearings. The medium level of eccentricity and high crush ensure improved oil retention and better seating, while the hardened steel back provides increased strength.

Designed without flash plating, the MS-1949H bearings offer better seating and are ideal for engines operating in the medium RPM range. They are not intended for high-performance or racing applications but are perfect for standard rebuilds where the crankshaft has standard fillets. This set includes all 5 main bearings required for the complete crankshaft support, ensuring a reliable and durable rebuild.
