BMW E30 M3 S14 High Performance Rod Bearing Set

Designed to meet the rigorous demands of high-performance engine builds, 5150 High Performance Coated Rod Bearing Sets are a top choice for BMW S14B20, S14B23, S14B25, S14B27 engines. These bearings feature shells treated and coated by Calico, significantly reducing friction and enhancing overall engine performance.

The advanced coating not only aids in power generation but also provides superior resistance against "spinning" under extreme conditions.

This feature helps prevent catastrophic engine failure during oil pressure loss, ensuring reliability when it matters most.

Proven on and off the track, 5150 bearings have demonstrated superior longevity and performance compared to other options available in the market. When considering replacement rod bearings, 5150 provides the performance edge that discerning BMW enthusiasts seek, making it the smart choice for anyone serious about their engine's capabilities.
