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:

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:

Upgrade your BMW engine's performance with the Athena Cut Ring Head Gasket. This gasket replaces BMW part # 11121726619 and 11121726617 and is specifically designed for M50 & M52 iron block inline 6-cylinder engines found in E34/E36 chassis. Standard OEM & MLS gaskets can only handle a certain amount of cylinder pressure before they start to leak, making the Athena Cut Ring Head Gasket the recommended choice for applications making 16+ psi. A compression leak passing the head gasket can cause a range of issues, including engine overheating, loss of power, misfires, and in severe cases, catastrophic engine failure. Athena's gasket is crafted with premium quality reinforced M0115, an asbestos-free material that's original equipment approved and renowned for its superior quality. The AISI 304 stainless steel Cooper Rings bite into the aluminum head, providing maximum sealing capabilities around the cylinder bore and optimizing engine performance, even on engines with nitrous and/or turbo applications that exceed 2-bar boost. Before installation, it is crucial to have the mating surfaces of the cylinder head and block professionally cleaned and resurfaced to ensure they are completely flat. Please be aware that the gasket should have a size that is 0.5mm to 1mm larger than the piston. For example, if the piston measures 84mm, then the gasket should be the next size up, either 84.5mm or 85mm. Installation instructions: Make sure that the engine block and cylinder head surfaces are clean, flat, and free from any debris, oil, or coolant. Install the Cut Ring gasket on the engine block and ensure that it is properly aligned. Avoid twisting or bending the gasket during installation. Place the cylinder head on top of the gasket and install the head bolts or studs in their correct positions. Follow the manufacturer's recommended torque specifications and tighten the bolts or studs in the proper sequence to ensure even clamping force across the gasket. After the initial tightening, re-torque the head bolts or studs after the engine has been started and then allowed to cool to room temperature. This will ensure that the gasket is properly seated and compressed. It is recommended to not use any additional sealant on the MLS gasket, as it is already coated with a Viton rubber sealant. Using additional sealant can hinder the performance of the gasket.
