JDM Nissan SR20DE & SR20DET ACL Bearings

ACL is an engine builders top choice for their quality and consistency. Buy with confidence; you will find ACL in many cars on road as they are an Original Equipment supplier. Many racers, especially import racers, swear by both their stock and performance series crankshaft rod and main bearings. ACL premium bearings will not only hold up better and longer than OEM, but the special coating process will also help prevent premature engine bearing failures and expensive engine damage.

ACL’s new Aluglide bearings provide a combination of moderate to high strength, good seizure resistance and excellent wear resistance. These bearings are ideally suited to vehicles where reliability and long service intervals are desirable. Aluglide bearings are highly preferred in modern import engines that have been designed for aluminum based bearings as OE standard fitment.

ACL Race series performance bearings are for extreme endurance under harsh conditions. Plan on running high RPMs and big boost? Fatigue, stress wear, and failure are factors you won't have to worry about when you are running ACL's top of the line metallurgy in your SR20.


  • Please Note When Ordering Bearings:
  • Engine bearings require proper tolerance to be measured before purchase. If you are not sure what size bearings your build requires, please consult a professional engine builder. We are not responsible for incorrectly ordered bearings and can not take returns or provide exchanges on any engine internal components.
ACL Thrust Washers

ACL thrust washers are an often overlooked component of rebuilds. They prevent the crankshaft from moving around, thus keeping it in line with all of the other critical moving engine parts. It also helps the crankshaft to better stand up to stresses from clutch and flywheel operation.

ACL Rod Bearing Sets

When doing rods and pistons, it's a good idea to replace the rod bearings as well. Proper support via main bearings is crucial to prevent oscillations and wear that can damage the crankshaft and other components if the motor should move out of balance. ACL's high quality rod bearings will prevent fatigue, failure, and reduce drivetrain stress through their durable and strong design.


  • Note:
  • The SR20DET from the Pulsar GTiR has slightly different internals. Please be sure of your SR20 type before you order.

ALC Main Bearing Sets

ACL's main bearings are made of a softer metal so that you don't wear out your crank or engine block. Additionally, a thin layer of oil lubricates the connection between the bearings and the crank allowing the crank to "float" and reduce wear. Proper support via main bearings is crucial to prevent oscillations and wear that can damage the crankshaft and other components as the motor moves further out of balance.

Bearings with extra oil clearance will absorb the stress of higher horsepower motors greater, but will see increased wear during start up. We recommend these be purchased by experienced professionals only.
