Sneed4Speed R56 MINI Engine Main Bearing Set – Standard & Black Magic Race Series
Precision crankshaft support for N12 / N14 / N16 / N18 engines — daily-driver durability or race-ready bottom-end strength.
The SneedSpeed R56 Main Bearing Set delivers critical internal support for the crankshaft and rotating assembly on 2007–2016 MINI Cooper, Cooper S, and JCW (R55-R59) engines with N12, N14, N16, or N18 powerplants. These bearings are engineered to control oil film, reduce friction, and withstand both daily use and performance demands with options tailored to your build goals.
Product Overview
When an R56 engine goes together — whether during a stock rebuild or a performance overhaul — main bearings are a foundational component in the bottom end. They sit between the crankshaft journals and the block, managing oil clearance, friction, and load distribution. High-quality bearings promote stable oil pressure and protect the crankshaft from wear or fatigue, especially under elevated RPM or boost.
This set offers two engineered options to match your build intent:
-
Standard Main Bearings — premium OEM-spec tri-metal construction for reliable daily use and mild performance applications.
-
Black Magic Race Bearings — advanced race-spec tri-metal design with SneedSpeed’s Black Magic anti-friction coating to improve oil film control, reduce operating temperatures, and extend bearing life under severe loads.
Key Features
-
Direct fit for R56 MINI N-series engines (N12, N14, N16, N18) — engineered to OEM dimensions for precise fitment.
-
Precision matched for stock or performance crankshafts — supports oil clearance consistency and crank stability.
-
Improved lubrication and wear resistance — helps reduce friction and extend service life.
-
Black Magic coating option — engineered for engines that see high RPM, high boost, or extended track duty.
-
Designed and tested by SneedSpeed race engineers — developed with real-world performance data.
Application Guidance
-
Standard Bearings: Ideal for rebuilds, daily drivers, and mild performance engines where OEM-level longevity matters.
-
Black Magic Race Bearings: Recommended for engines with boosted tunes, high RPM limits, track use, or higher internal stresses where bearing durability and oil film control are critical.
Why Quality Main Bearings Matter
Main bearings are a critical contact point between the crankshaft and the engine block. If bearings are underspecified or worn, oil pressure instability, accelerated wear, and crankshaft fatigue can follow. High-quality bearings help maintain consistent lubrication, reduce parasitic losses in the bottom end, and support long-term crankshaft health — especially as performance demands increase.
