This King Engine Bearings set is ideal for low to medium-load engines. The bi-metal aluminum construction and lead-free composite are designed for reliable performance in these applications.

About this part

Product Details

Built with a bi-metal aluminum material, this King Engine Bearings main bearing set is designed for engines that don't see extreme loads. The lead-free composite is an environmentally safe choice, making it a solid option for many Nissan applications from the late 80s through the early 2000s, including models like the Frontier, Altima, and 240SX.

King has been specializing in bearings since 1960, focusing on delivering a well-built product. This set is sized at +0.25mm, meaning it's intended for use when the crankshaft journals have been machined down by that amount during a rebuild. This ensures a proper, snug fit and correct oil clearance for the engine's main bearings.
