The Calico-coated bearings feature advanced anti-friction technology, ensuring consistent lubrication even under high-stress conditions. This makes them ideal for both high-performance engines and street vehicles, offering reliable performance and protection against bearing-related failures, such as spun rod bearings—especially during cold starts.
In addition to reduced friction, these coated bearings provide excellent thermal resistance, which is crucial for engines subjected to forced induction or racing. This thermal resilience also acts as a safety net, reducing the risk of engine failure in situations involving oil pressure loss.
With a proven track record of extended durability and superior performance, the 5150 AutoSport rod bearing kit offers an unmatched level of reliability compared to standard OEM bearings, making it an excellent choice for anyone looking to protect and enhance their BMW S14
