What does 'STD' size mean for these bearings?

STD stands for standard size. This means the bearings are designed to fit crankshaft journals that are still within the manufacturer's original specifications. If your crankshaft journals have been machined undersize, you would need a different bearing size.

What vehicles does this main bearing set fit?

This set fits a broad range of vehicles including the Chrysler PT Cruiser, Dodge Caravan, Dodge Stratus, Jeep Liberty, and Plymouth Voyager, among others. It's always best to check the full fitment guide for your specific year, make, and model.

Are these bearings suitable for high-performance engines?

These bearings are made with a bi-metal aluminum material and are ideal for low to medium-load engines. For high-performance or high-load applications, you may want to consider a different bearing material or series.
