What does the +0.25mm size mean for these bearings?

The +0.25mm designation indicates that these bearings are slightly larger than standard size. They are intended for use when the engine's crankshaft connecting rod journals have been machined down by 0.25mm during an engine rebuild to ensure proper oil clearance.

What type of engine is this bearing set best suited for?

These bearings feature a lead-free composite and bi-metal aluminum construction, making them ideal for engines that operate under low to medium load conditions. They are not typically recommended for high-performance or racing applications that demand extreme load capacity.

Are these bearings environmentally safe?

Yes, the manufacturer specifies that these bearings utilize a lead-free composite material, making them an environmentally safe option.

About this part

Product Details

These King Engine Bearings connecting rod bearings are built with a lead-free, environmentally safe composite material. This bi-metal aluminum construction is a solid choice for engines that don't see extreme loads, like many of the Mitsubishi 4D55T, 4D56T, and 4G52 engines they fit. They are precisely sized at +0.25mm, meaning they are meant to be used when the crankshaft journals have been machined down by 0.25mm during an engine rebuild.

Founded in 1960, King Engine Bearings specializes in making just bearings, focusing on supplying a well-built product. This set is designed to be a direct replacement for the original bearings, helping to restore proper oil clearance and reduce friction in the engine's rotating assembly. They are a popular option for many Chrysler, Dodge, and Mitsubishi vehicles from the 1970s through the late 1980s.
