Our VAC Main Bearing Sets are made to our specs and specially coated to reduce friction to a minimum; enabling lower temps and faster revolutions in your expensive BMW engine.
Our coated bearings are thermal breakdown resistant, helping to prevent premature engine failures under stress when things are most critical. Embedibility factor is also excellent; this allows our bearings to keep dirt and debris from harming the crank surface better than a standard bearing.
These bearings can last much longer than any normal bearing set and have become a favorite product of all our race and engine building customers around the globe. They have reported unparalleled wear characteristics under all conditions and even "saved" engines during oil pressure loss.
Each of our BMW bearing sets are made to our specifications with the same technology used in US military, NASCAR, and other engines that require "mission critical" quality. We use these in all our high performance BMW engine builds.

• If you are looking for high performance Main Bearings, this is the set for you.
  We recommend these not just for racing; they make a great upgrade for street or FI builds as well.

• Fits all S54B32 engines, including M Coupe / Roadster and E46 M3

VAC Tech Notes:
