What does 'STD' size mean for these bearings?

STD stands for standard size. This means the bearings are manufactured to the original equipment manufacturer's (OEM) specifications and are intended for use when the engine's crankshaft journals are still within their original, unworn dimensions.

Are these bearings environmentally friendly?

Yes, these main bearings are made with a lead-free, environmentally safe composite material, aligning with modern environmental standards for engine components.

What is the benefit of bi-metal aluminum construction?

The bi-metal aluminum construction offers good thermal conductivity, which helps to dissipate heat away from the bearing surface. This is important for maintaining consistent bearing performance and longevity under operating conditions.
