What is the difference between standard size (STD) and undersize bearings?

Standard size bearings are meant to be installed on a crankshaft that is within factory specifications for diameter and finish. Undersize bearings, often indicated by suffixes like -010 or -020, are used when the crankshaft has been machined down to remove damage or wear.

What does the 'HX' in the part number signify?

The 'HX' designation in ACL bearing part numbers typically refers to their high-performance overlay. This is a specialized coating designed to offer enhanced durability and resistance to wear under demanding conditions.

Do these bearings come with new rod bolts?

This product is a set of connecting rod bearings only. New connecting rod bolts are not included and should be sourced separately if required for your engine build or rebuild.

Product Details

ACL has been making engine bearings for a long time, and their 2000+ Series is a popular choice for builds that see more than just daily driving. These bearings are made with a tri-metal construction, which is a well-built combination of steel, aluminum, and lead-tin overlay. This design helps them handle the increased loads and higher temperatures that can come with performance driving or just a well-used engine. The 'HX' in the part number indicates a high-performance overlay, and the 'STD' means they are standard size, meaning they're meant to be installed on a crankshaft that hasn't been machined undersize. The 0.001 clearance spec is very tight, so these are intended for engines where precision is key, often in performance or rebuilt applications.

When you're rebuilding an engine or upgrading components, using the right bearings is essential. These ACL bearings fit a range of popular vehicles, including the Lotus Elise and Exige, Pontiac Vibe, and Toyota Celica, Corolla, and Matrix models equipped with the 1796cc 2ZZGE engine. Make sure your crankshaft journals are in excellent condition and within factory specifications for size and finish before installing these bearings. If your engine is making knocking noises or you're performing a performance build, this set is a solid option.
