Title: Main Bearings recommendation Post by: Black_65 on October 28, 2022, 19:49:08 pm Evening all,
I need some help on sourcing a part number for the BMW main bearings used on VW conversion but for ACL race bearings. I know the part number of the ones used (87 434 600) but I thought I’d try ACL ones. I’ve emailed ACL with no reply, I’ve also called the U.K. supplier who refused to supply me the part number of the bearings required matched to the one listed above. They had no stock and unknown when they will be in so I’m trying to source some. But I’d like to hear what people are running any recommend. Thank you.

Ps they are hardened frames and can withstand more force than std bearings and you would like larger bearing clearance 7M1532HX-STD (0.025mm) They can handle E85 mixing in the oil without damage to the bearings |
