Our VAC Bearing Sets: Precise construction and special coating to keep bearing failure at a minimum.
The mighty and powerful BMW N54/N55/S55 has an "Achilles Heel;" its rod bearings. As great and powerful as BMW made the N54/N55/S55 engine, they left it lacking in a critical area: rod bearing reliability.
Now one of our best sellers has gotten even better! With the VAC Motorsports' complete High Performance Coated Rod Bearing Kit, you get all the parts you need to easily swap out the factory connecting rod bearing shells and bolts in one simple kit.
Our N54/N55/S55 bearings are embraced by BMW engine builders worldwide. Our coated bearings are "friction resistant," making thermal breakdowns that can occur due to lack of lubrication a much less common occurrence. This coating helps to prevent premature engine failures on street cars, and spun bearings under stress at the track when things are most critical.
Proven by customers to help you finish the race, even with loss of oil pressure!
Tech Notes:
- As with all bearings, please check your tolerances and size before installation. Due to the specialized tools needed, professional install is highly recommended.
- There are no returns available on any engine bearings.
Why do VAC bearings do a better job?
Our bearings are not only made with great precision and repeatability, but their coating is widely praised as one of the best upgrades on the market. It is a physical layer (not just a treatment to the layer) with both a high embeddability factor, and a 'dry lubricant' property. What makes them so good is that they can run the tolerances that BMW engines like and not see the typical failures that one associates with the OEM units.
Unlike treated bearings that must be sized very close to OEM for proper results- these bearings have the ability to run well on both sides of engine tolerance and work fantastically for the cold starts that both street and race engines see. All VAC engines are built with our coated bearings and we know they work great.
