BMW S65 BE Bearings Connecting Rod Bearing Upgrade Set is designed to address the known flaws in the factory BMW rod bearings, particularly for the S65B40 engine. Manufactured by Clevite to BE Bearing specifications, this set provides a crucial upgrade with its enhanced materials and design, ensuring improved performance and durability.

The original BMW bearings have minimal clearance, which leads to premature wear and potential engine failure. This upgrade replaces the tin-aluminum factory bearings with a superior silver-oxide-coated tri-metal "F" series design. The new bearings can handle 30% more load, offer better performance in low oil conditions, and are more forgiving of foreign particles in the oil. Designed specifically for BMW S65 engines, these bearings provide optimal performance for high-horsepower applications.

  • Designed specifically for BMW S65B40 engines
  • Silver-oxide coating withstands 30% more load capacity
  • Improved performance under low-oil and boundary conditions
  • Stronger backing material for enhanced durability
  • Corrects factory BMW rod bearing clearance issue
  • Ideal for high-horsepower applications and factory 10W60 weight oils
  • Complete set for 8 cylinders, ready for installation

Fits the following BMWs:

  • 2008-2013 E9X BMW M3 (S65)

Designed and manufactured by Clevite to BE Bearing specifications.

These bearings replace the factory BMW rod bearings. The original BMW bearings have too little clearance, which leads to premature bearing wear and can cause early engine failure.  Furthermore, the factory BMW bearings are made from tin-aluminum which are 5-times harder than a softer lead-copper bearing design. A softer bearing is better for your engine and more tolerant of foreign particles suspended in your oil.

These BE Bearings feature a state-of-the-art Clevite Tri-Metal design with the Clevite Tri-Armor(tm) coating.

  • Lead-copper design for greater durability and easy tracking with oil analysis like Blackstone (recommended).
  • Designed with extra clearance to "fix" the BMW rod bearing design flaw.
  • Designed for use with factory 10W60 weight oils.
  • Tri-Armor coated for low conditions during cold start
  • Ideal for start-stop vehicles
  • Applicable for BMW engines S85B50
  • Standard Clearance
  • Sold as complete set (10-cylinders)

Fits the following BMWs:
2005-2010 E60 BMW M5
2005-2010 E63/64 BMW M6

Achilles Motorsports uses an extremely hi-tech Dry Film Lubricating process that will keep friction to a minimum allowing your engine to rev faster without worry while keeping oil temperature lower. Perfect for high-performance street, sprint, or endurance racing engines, this specialized coating protects vital engine bearings on dry engine starts and during extreme temperatures and high RPM operation. This specialized coating is the same process that is the choice of professional engine builders around the world, used on all NASCAR, ALMS, and Grand-Am engines. Achilles' bearings provide increased insurance against mechanical thermal breakdown compared to the OEM type bearing, showing much less wear during routine inspections. Note For high-performance and racing engines, we strongly recommend upgrading the OEM type connecting rod bolts to an ARP Connecting Rod Bolt Set to keep your bearing and caps tight even under the most extreme conditions, eliminating potential walk and bearing problems. As with all racing and performance bearings, professional installation is required. Please check all clearances as per the manufactures specifications.
