What does 'STD' mean for these bearings?

STD stands for standard size. This means the bearings are made to the original factory specifications and should fit your crankshaft and engine block without requiring any machining, assuming the original journals are not worn beyond their service limits.

What vehicles does this bearing set fit?

This set is compatible with a range of Chrysler products including the Chrysler LeBaron (1978-1980), Dodge Aspen (1976-1980), Dodge Charger (1970-1974, 1976), Dodge D150 (1977-1980, 1983-1987), Dodge Dart (1970-1976), and Plymouth Volare (1976-1980).

Are these bearings suitable for a performance engine build?

These are standard-size replacement bearings designed for stock or mild performance applications. For high-performance or racing engines with significantly increased horsepower or RPMs, you may need to consult with a specialist about bearings with different clearances or materials.

Product Details

You get a full set of main bearings in this kit, which means one box handles the core components for your engine rebuild or repair. These ACL bearings are made to fit Chrysler products from 1976 through 1987, covering a range of models like the Dodge Aspen, Plymouth Volare, and Dodge D150. Proper main bearing function is critical for keeping your crankshaft spinning smoothly within the engine block, reducing friction and wear.

This set is a standard size (STD), meaning it's designed to replace your original bearings without needing any machine work on the crankshaft or block, assuming the journals are still within factory specifications. ACL has been making engine bearings for a long time, and these are well-built to handle the demands of daily driving and typical engine operation. They are made from a durable material that resists wear and maintains oil film integrity, which is key to protecting your crankshaft.

When you're rebuilding an engine or replacing worn bearings, it's important to ensure the crankshaft journals are clean and within spec before installation. If you're unsure about the condition of your crankshaft or block, it's always a good idea to have them inspected by a professional. This kit includes the main bearings needed to get your engine back in running order.
