Best Rod Bearing Replacments
I have been reading the post's for years now. I have tried to review everything that I could find with regards to replacements. So if this sounds like a question that has been answered numerous times I apologize in advance.
What I am really trying to see is if there is a consensus on the best after market replacement non OEM rod bearings. I have seen that there are a number of companies that appeared to still be making replacement bearings, including BE, VAC, and ACL. Are there any that I am missing? I currently have 64,000 miles, with a second stage cold air intake, ESS ECU tune, with full Arkropovic exhaust system. I car is not a daily driver, and it gets a fair bit of track use. This will be my first rod bearing replacment. I am doing it as part of preventative maintenance given the amount of track use that the car gets.

The general consensus here leans heavily toward BE bearings and bolts. Some people go with VAC, ACL, or OEM for various reasons, but the majority seem to agree that BE is the best solution based on the very detailed analysis and technical findings they have shared with the community. Not to mention the long list of BMW race shops that support them. Personally, I believe BE bearings are the only true "solution" to the bearing problem but I don't say that as a fact, just a very strong opinion.

Or, has anyone heard of any issues with the added clearance bearings having failures?

I had mine replaced last week, BE with BE ARP bolts. 65k on engine..I'm sure my bearing wear will be different than yours but mileage was approximately the same. I posted the pics of mine in the Rod Bearing thread on this forum. While I cannot comment on the wear just yet....the piece of mind I now have is priceless...

Were you doing oil analysis prior to seeing them at 50?

Why would he use that oil if he had replaced the bearings? It's hard to imagine not using the mfg suggested oil after fixing the bearings.. seems risky, but I'm not one to be the judge of it, just curious.

My local mechanic is actually trying to source a company called KING that I had not heard of nor have seen in any posts. I believe they do mostly after market race bearings and even have some aviation bearings.
Has anyone used their rod bearing's?

I'd stick to BE. There's no reason to risk using Joe Bob's bearings when BEs exist.

King is also very good. As is ACL. If King has S65/S85 crank and rod bearings, that would be great.

Unfortunately that does not mean much. I am over 50,000 km on WPC treated stock bearings, which does not mean much, either. Have to know what they look
like to assess. Those BE bearings with 50,00 km in the picture above look good. In a few years we will know more as bearings get changed a second time and we see how they have worn. I am planning to do mine again and will probably pull the motor and do the main bearings as well. |

King Bearing is very reputable in the tuner industry. My tuner shop who does all the work on my other car use King Bearing on their all built engines. They also looked into them when they replaced the bearings on my m3, unfortunately King don't have anything readily available for our engine. It'll have to be a custom made one off, which means $$$$$. So I went with BE.

King doesn't have bearings for these engines. Your mechanic needs to get with it and go with what's already available, like BE, which is already proven.
It would be fantastic if King would utilize their resources to make a set of main bearings, but it's probably not likely to happen. We don't need more rod bearing options. |

Be sure to let my local guy here know. When I was on the BE website it appears that their bearings are back ordered until December. Has anyone heard of distributors for their bearings that still have them in stock?
