HK-Series Extra Oil Clearance Main Bearings for GM LS

For engine builders who require precise oil clearance tuning, the Clevite77 HK-Series Main Bearing Set (MS2199HXC) is the ideal solution for GM LS-series engines. These bearings are specifically engineered with extra oil clearance, allowing for better oil flow and cooling in high-RPM and high-load environments. Combined with a high-performance coating, the HK-Series provides the ultimate protection for your crankshaft.

Key Technical Features

  • Series: HK-Series (Extra Clearance)
  • Coating: Performance anti-friction coating
  • Fitment: GM LS-Series Engines
  • Size: Standard (Extra Clearance)
  • Material: Tri-metal construction

In high-performance LS builds, managing oil temperature and pressure is vital to preventing bearing failure. The extra clearance provided by the HK-Series allows for a thicker oil film, which is essential when running high-viscosity oils or when the engine is subjected to sustained high-RPM operation. The advanced coating further enhances the durability of these bearings, reducing friction and protecting the journal surfaces during the initial break-in period and beyond. When you are pushing the limits of your LS engine, you need components that offer both performance and peace of mind. Clevite77 remains the leader in bearing technology, providing the precision that professional engine builders rely on. Find the exact clearance specifications you need for your next high-performance build at GGCRACING.
