What does 'Standard Size' mean for these bearings?

Standard size bearings are meant to be installed on a crankshaft that has not been machined undersize. If your crankshaft has been ground down to a smaller size due to wear or repair, you would need an 'undersize' bearing set.

What is the 'HX' designation in the part number?

The 'HX' designation typically indicates a specific high-performance material or construction used by ACL for their bearings. These are often designed for improved strength and durability, suitable for performance applications or demanding engine rebuilds.

Do these bearings come with assembly lube?

This set includes the main bearings themselves. It is recommended to use a high-quality engine assembly lube during installation to ensure proper lubrication and prevent damage during initial startup.

Product Details

Doing an engine rebuild on your classic Ford, Mercury, Lotus, Morgan, or TVR with a 1500-1600cc OHV or Twin Cam engine? This ACL High Performance Main Bearing Set is a solid choice for getting your bottom end back in shape. Main bearings are critical for supporting the crankshaft and ensuring it spins smoothly within the engine block. When it's time to replace them, especially in a performance or rebuild scenario, you want a well-built set that can handle the demands.

ACL has been making engine bearings for a long time, and this set is built to their high standards. They're a standard size, meaning they're meant to fit on a crankshaft that hasn't been machined undersize. The 'HX' designation often points to a specific material or construction for improved durability and performance, suitable for engines that might see harder use than a daily driver. These bearings are designed to provide consistent oil clearance and support, which is key for engine longevity and performance.

When you're putting an engine back together, especially one from the 60s and 70s, using a reputable brand like ACL for your main bearings is a smart move. Make sure to clean your engine block and crankshaft thoroughly before installation, and always follow the manufacturer's recommended oil clearance and torque specifications to ensure a successful rebuild.
