The comparison here is not even between BE and Acl. BE is not a manufacturer, rather it's Clevite. A simple Google search will yield many pages from forums for other performance cars comparing the two manufacturers. Conclusion: Both are damn good and reliable rod bearing manufacturers. Some prefer Acl while others prefer Clevite. It was difficult to find one negative review about the Acl race bearings after scrolling through hundreds of pages on the web. So let's not say, we are comparing "Apples to Oranges". Kobe said it best when people kept on debating whether MJ or LBJ is the GOAT. He said, "We can enjoy one without tearing down one." On a side note, Acl race bearings can be purchased for as low as $185.00. Compared that to BE that is sold for Min $535.00 and listed on the BE website for $589.00. That's a huge price difference! I will dedicate another post comparing the material and clearance of the two bearings. I'm studying a 190 page detailed catalog written by Acl about their bearings and many other catalogs on their website. Also studying the outstanding research done by the BE team. Few fun facts thus far in my in depth research on bearings: (I'm doing my PhD at the moment so love to do research and read through hundreds of pages) BE considers the Tri-Metal design as the world's best bearings design. It's states on their website, "Look in the best automotive engines, and you're likely to find a Tri-Metal bearing design." This was one of the critiques of the earlier bearings that were designed for our cars. Spoiler Alert: Acl race series bearings also has the same Tri-Metal design. Clearly clearance is one of the biggest concerns raised by BE. The following is written on the website, "The original BMW bearings have too little clearance, which leads to premature bearing wear and can cause early engine failure." They also note how all the earlier bearing designs failed to address this clearance issue (which is hundred percent true). Acl race series bearings clearly has extra clearance as well. People should know about and have the option of buying whichever bearings they would prefer. In my opinion, You can't go wrong with either of these two choices. Additional analysis will be provided upon completion of my Rod Bearings job which is scheduled to be done next weekend. |

Can we all just stop with the bearing "dick measuring" contest? Seriously buy whatever you feel comfortable with. I went with VAC because my shop has used them for years with zero failures and I get a huge discount on them. Literal convenience was the deciding factor. I've installed BE,VAC, WPC and OE. They have all performed flawlessly and the engines are still working. I swear until each bearing manufacturer is tested in the same engine, under the same conditions and test criteria, objectively, we can all just stfu about it.

I agree. Any new bearing is good. I installed WPC treated stock 4 years ago but would install any others and be happy as well. If I had the choice, I would go with added clearance lead containing bearings.

That's the argument I was trying to make all along. For me, ACL was due to convenience and price. It was a no brainer. |

It's been fine, still early days of course.
Engine is noticeably quieter, less clacking sounds if that makes sense, though can get that from fresh oil change in general too I guess. Moving to the HX, I've also moved back to TWS 10W-60, where previously I was running Mobil1 5W-50. |

I went with the HX. It has more clearance than BE. Can't use thin oils with it. But H-STD also has an additional clearance over the OEM bearings but not as much as the HX ones. Both are absolutely fine.

Autotalent, BE, many thanks for taking time to measure and post. Don't mean to bug you guys but curious about your view of issue with this clearance.
Interestingly read about your oil pressure measure coming down 4% isch by increasing clearance by 50-75% or so. Any hints on where the pressure would go due to another 25% isch? |

More great information! BE reaffirms that it will remain the gold standard for these engines.
BE has been the only company to bring forth voluminous amounts of concrete data. Not ACL, VAC, Lang, or anyone else. We have used BE's measurement data to educate ourselves, see past marketing pitches, create technical based discussion, and help confirm the need to get our bearing services done. That alone should be enough to purchase BE bearings and promote such an operation to thrive. To consume and redistribute their research but buy cheaper bearings is to pay them lip service. |

Anyways, a suppliers even assumingly superior work in my book doesn't mean they are untouchable for competition. Suggesting a competitor yo have less optimized product - which is again interesting- certainly invite to explanation. |

Additionally, just because their website says unavailable doesn't mean their listed vendors don't have any. We've had them in stock all this time but only one customer contacted us for purchase. |
