BMW S54 VAC Performance Coated Rod Bearing Kit is highly regarded by BMW engine builders worldwide for its superior quality and performance. Ideal for both forced induction and naturally aspirated builds, these coated bearings are designed to be friction-resistant, reducing the risk of thermal breakdowns due to inadequate lubrication.

The VAC Performance Coated Rod Bearing Kit is proven to help maintain engine reliability, even in situations with reduced oil pressure.

  • Enhanced Durability: Coated bearings are friction-resistant, reducing the risk of thermal breakdown.
  • Increased Reliability: Helps prevent premature engine failure and spun bearings under stress.
  • Versatile Performance: Suitable for both forced induction and naturally aspirated engine builds.
  • Proven Track Record: Tested by customers to ensure reliable performance even with oil pressure loss.

VAC Tech Notes:

  • Ensure proper tolerance and size checks before installation.
  • Professional installation is recommended due to specialized tools required.
  • Returns are not available on any engine bearings.

Achilles Motorsports uses an extremely hi-tech Dry Film Lubricating process that will keep friction to a minimum allowing your engine to rev faster without worry while keeping oil temperature lower. Perfect for high-performance street, sprint, or endurance racing engines, this specialized coating protects vital engine bearings on dry engine starts and during extreme temperatures and high RPM operation. This specialized coating is the same process that is the choice of professional engine builders around the world, used on all NASCAR, ALMS, and Grand-Am engines. Achilles' bearings provide increased insurance against mechanical thermal breakdown compared to the OEM type bearing, showing much less wear during routine inspections. Note For high-performance and racing engines, we strongly recommend upgrading the OEM type connecting rod bolts to an ARP Connecting Rod Bolt Set to keep your bearing and caps tight even under the most extreme conditions, eliminating potential walk and bearing problems. As with all racing and performance bearings, professional installation is required. Please check all clearances as per the manufactures specifications.
