Rod bearing changeout time :) has anyone used ACL brand? Looks like they have some good reviews for other non-BMW vehicles.

Time to do the rod bearing PM now that Im at 75k miles. Looking up all of the posts on the BE bearings, OEM, etc...but cannot find much on the ACL brand.

They are several hundred $$$ less than the BE or OEM, but are in line to other bearing sets for other non BMWs. Anyone used these in their s85? Im definitely not cheap ( my M makes the 3rd of my small BMW fleet of 3, lol ), but hate to just stick with a brand if another company offers a competitive product that performs and is not jacking up prices just because they are for a BMW.

I'd stick with OEM or the Improved BE spec bearings produced by the OEM manufacturer personally. I'm using BE spec for mine, in shop right now actually for it

Don't think you'll read much about the ACL bearings here....I've not heard of it. I installed BE's in mine and they are doing fine so far.

Would be interesting to know for sure. At about $235 a set for the ACLs versus $660 for the BEs there is a huge price difference. Im almost tempted to buy two sets of the ACLs and run one set for a while then tear it apart to see...if only it wasnt such a task to take everything off to get to them. I dont plan to ever track my car...just the normal spirited driving, so I would say that almost any bearing with the proper clearance would hold up fine.

My problem is that I bought my car used so I have no idea of how it was treated

I would love to know the outcome of this. I saw these a few weeks ago and didnt think much about them, but maybe we would save some cash because of the Brand of the rod bearings. Also considering most of have never heard of anyone running these rod bearings in our engines. Hopefully they have the characteristics to compete with BE bearings and we can save the extra $300 for a different mod as well

Im going to give the sales rep closest to me a call tomorrow to inquire more in these as the online info looks promising. Seems the race series ( under $250 USD ) has about .011 copper layer so Oil Analysis should be able to easily pickup if you get into the copper layer before you hit the steel backer and do some crank damage.

The other promising thing is that they offer a bearing with an extra .001 oil clearance versus the standard size so that would help with the OE bearing clearance.

Ill post back once I contact them to get some low down on their quality, return policy if they are not in spec, etc...

Heres a pic of their layers...

They work. From what I have seen they work the same if not better than BE. I used them 4-years ago and saw one of my 6.0 from back then and the bearings looked fabulous considering the abuse they took. Bearings cost like $3/shell. Just shows you how much markup BE has. Bearings are big business with these m cars and I am not about to fight anyone on which is best as I don't sell bearings. But you get my drift here.

Good to know someone has tried them with success indeed. I spent a few hours on the phone and email yesterday in order to get more info on these. Seems they show in ACLs catalog, but several places in the US could not cross the P/N even though they sold ACL bearings. There is an Amazon/eBay seller that has them and they also have a brick and mortar store in Cali, you can get them direct from ACL US, or you can get them from an Australian company. Prices go like this:

From ACL US direct: ~375 USD
From boostproject (Amazon/eBay/shop in Cali): ~235 USD
From M.D. Spares (Australian company): $214 AUS which is about $165 USD....thats for the complete set.

From the above, looks pretty typical for pricing...ACL US direct is the list, but provide discounts to their distributors (which are listed as sales people on their site, but none have the info on these specific bearings, lol), boostprojects probably buys them from Australia and makes about $100 per set to handle and the faster shipping in the US, and M.D. Spares is getting them locally in Australia from the factory so their price is the best.

Overall, right in line to prices for other non-S85b50 bearings in the world which makes sense as when it is all boiled down, they are just a rod bearing.

The website with the info is aclraceseries.com and it all reads good plus with the copper layer one should be able to pickup the wear with Oil Analysis.

I pulled the trigger on a set from boostprojects for the .001 additional clearance as the M.D. Spares web site stated that there are no returns for international orders and I wont know the quality of the dimensions till I get some plastigage on them during the rebuild. I might also buy a set from M.D. Spares out of Australia of the Standard size just to see if I need to mix them to get the gaps spot on...heck, if $165 USD why not, lol. If I find I do need to mix them I will have another complete mixed set for a project car or something.

Wish me luck ! Well see when I check the gaps once I start this rebuild in a few months. Ill be sure to post back, but not planning to do this till June so it will be a couple months
