What does the '0.020' in the part number 5M8088H-.50 mean?

The '-.50' in the part number indicates that these are 0.020 inch undersize bearings. This means they are designed to be used with a crankshaft that has been machined down by 0.020 inches to correct imperfections or wear.

Are these bearings suitable for a stock engine rebuild?

Yes, ACL Race Series bearings are well-built and can be used for both performance builds and thorough stock engine rebuilds. Their overlay material is designed to handle the stresses of engine operation.

What other parts are typically needed when replacing main bearings?

When replacing main bearings, it's common practice to also replace the connecting rod bearings (also known as rod bearings). You'll also need new engine oil and an oil filter for the reassembly.

About this part

Product Details

Rebuilding the top end of your Lexus V8 1UZFE 4.0L engine? Or maybe you're doing a full engine overhaul? When it comes to the critical rotating assembly, you need bearings you can trust. This ACL Race Series crankshaft main bearing set is designed for performance and durability, offering a solid option for your build. These bearings are a 0.020 inch undersize set, meaning they are intended for crankshafts that have been machined down by 0.020 inches to true them up.

ACL has been making engine bearings for a long time, and their Race Series is built with a focus on strength and consistent performance. They use a well-built overlay material that can handle the pressures and heat generated in a performance engine. The 0.020 inch undersize is a common machining size, so if your crankshaft needs a bit of work, this set is ready to go. Proper installation is key with any bearing, so make sure your machine shop is on point with the crankshaft grinding and your engine assembly is clean.

This set fits a wide range of popular Lexus and Toyota V8 applications from the early 90s through the late 2000s. If you're working on one of these vehicles and need main bearings for a performance build or a thorough rebuild, this ACL set is a strong contender.
