Enginetech BB146J-25 Connecting Rod Bearing Set GM 1.8L 1796cc DOHC 0.010in Oversize

The Enginetech BB146J-25 is a connecting rod bearing set engineered for GM 1.8L (1796cc) DOHC four-cylinder engines. This set is manufactured to 0.010-inch (0.25mm) oversize specifications, making it the correct choice during engine rebuilds where crankshaft journals have been machined undersize to restore a proper bearing surface.

Enginetech has transitioned their rod and main bearing line to an advanced aluminum-silicon alloy material, which delivers performance equal to or exceeding traditional tri-metal designs. The high silicon content dispersed within the aluminum alloy provides exceptional load capacity, wear resistance, and conformability for long-lasting engine reliability.
