What is the difference between standard size and undersize bearings?

Standard size bearings are meant to be installed on a factory-spec crankshaft. Undersize bearings, like -010 or -020, are used when the crankshaft journals have been machined down to remove wear or damage. These are standard size bearings.

Do these bearings come with assembly lube?

This set includes the rod bearings themselves. It is highly recommended to use a quality engine assembly lubricant when installing new bearings to ensure proper initial lubrication and prevent damage.

What is the material of these ACL rod bearings?

These ACL bearings are made from a tri-metal material. This construction is known for its strength and ability to withstand higher loads and temperatures compared to standard bearings.

Product Details

ACL has been making engine bearings for decades, and this standard size rod bearing set for your INFINITI G20 is one of their staples. These bearings are crucial for keeping your engine running smoothly by reducing friction between the crankshaft and connecting rods. If you're rebuilding your SR20DE or SR20DET engine, or just looking to replace worn-out bearings, this set is a solid option.

These are the 17mm wide standard size bearings, meaning they're designed to fit perfectly on a factory-spec crankshaft without needing any machining. ACL uses a well-built tri-metal material that's known for its strength and ability to handle higher loads, which is important if you're pushing your engine a bit harder than stock. They're a popular choice for many SR20 builds because they offer improved durability over OEM bearings without breaking the bank.

When you're installing these, make sure to follow the manufacturer's lubrication and torque specifications carefully. Proper installation is key to getting the most out of these bearings and ensuring your engine lasts.
