BMW Rod Bearings for BMW E46 (1999-2005) M3

Clear BMW chassis
Rod bearings continue to be a sore subject among M3, M5, and M6 owners. The rod bearings in the S54 I6, S85 V10, and S65 V8 have been known to fail within 60,000 miles. There could be a number of reasons for premature failure with a lot of finger-pointing as to the real cause. Whatever the reason, rod bearings are wearing out sooner than expected and their replacement should be considered a required preventative maintenance item. We suggest a replacement interval of between 60,000-80,000 miles with frequent engine oil analysis done along the way. Driving moderately and allowing the engine to warm up before hard use will also extend rod bearing life. Our rod bearings and overhaul kits are developed with input from our own service department and we offer everything needed to replace the bearings. In most cases removing the subframe, and supporting the engine from above, is the best method to access the bearings. Professional installation or previous experience is very strongly recommended.

These WPC-treated bearings are the best we have seen for the S54. WPC is a shot-peening treatment at a microscopic level. It's perfect for sensitive surfaces like bearings. The WPC treatment removes imperfections and high spots, while creating a surface that retains oil better than the original surface. This greatly reduces friction. The bearings in this kit are factory BMW bearings that are sent to WPC for treatment. The treated bearings are stronger with less metal fatigue and less friction than buying off-the-shelf bearings from the dealer.

Price is for a complete set of S54 upgraded rod bearings.

Replacing the rod bearings requires mechanical knowledge and skill, a clean workspace, and several specialist tools. Our preferred procedure is to leave the engine in the car but remove the front subframe. The engine must be supported from above with an engine brace. Removing the front subframe involves disconnecting the control arms and steering rack and steering column. The oil pan can then be removed and you can access the connecting rods and bearings. Replacing the rod bearings themselves is straightforward but patience and forethought will be extremely helpful. In addition to analyzing the severity of the rod bearing wear, the crankshaft must also be inspected closely for damage. Rod bearings that have been severely worn may have damaged the crankshaft (requiring replacement or machining).Replacing the rod bearings requires mechanical knowledge and skill, a clean workspace, and several specialist tools.

The S54 engine has a known history of rod bearing failure, and if your engine is higher mileage, don't let this catastrophic failure happen to you. Replace your rod bearings and prevent a spun bearing which can trash your crankshaft.

WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both.

Kit includes

  • Upper and lower WPC treated rod bearings for extra protection against wear
  • Hardware
  • Oil filter
  • Castrol TWS Edge Professional
  • Oil pan gasket
  • Oil pan cover gasket
  • RedLine assembly lube
  • Connecting rod bolts

Fits the following BMW's

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 S54
  • Standard size
  • Sold as complete set (6-cylinders)

Fits the following BMWs:
2002-2006 E46 BMW M3 S54
2002-2003 Z3 BMW M Coupe, M Roadster S54
2006-2008 Z4 BMW M Coupe, M Roadster S54
