ACL Cooper .25mm Oversized Performance Rod Bearing Set for Mini Cooper S 2001-2019 - 4B7787H-STD

If you're diving into the world of performance engines, you know that the right bearings can make a world of difference. These ACL Race Series Engine Bearings are not just any bearings; they’re crafted with a unique blend of design and metallurgy that really stands up to the demands of high RPM conditions. Whether you’re running a 4, 6, or 8-cylinder setup, these bearings are designed to keep your engine running smoothly and efficiently.

What’s cool about these bearings?

  • They’ve got a high-strength overlay plate that’s thinner than your average bearing, which means better fatigue properties. Less wear and tear equals more time on the road.
  • All rod bearings come with hardened steel backs. This isn’t just for show; it gives you better support for the bearing lining and helps keep everything snug in the housing.
  • Increased crush? You bet. This feature enhances bearing retention, so you don’t have to worry about any slipping or movement when the engine’s revving high.
  • By eliminating flash plating on the back, these bearings improve heat transfer. You want that heat dissipated efficiently to keep your engine cool and happy.
  • They’ve also upped the eccentricity to handle bore distortion at those high RPMs. This helps create hydrodynamic oil films, which is crucial for smooth operation.
  • The 3/4 grooved main bearings optimize the load-carrying surface area and oil flow to the conrod bearings, ensuring everything stays lubricated just right.
  • Tight wall tolerances mean you can maintain consistent clearances, which is essential for performance engines.
  • And let’s not forget about the enlarged ID chamfers on the edges. They accommodate those larger fillet radii on performance crankshafts, making installation a breeze.

Specifications:

  • Size options: STD, .025, .25
  • Oil Clearance: Standard

Fitment:

These bearings fit the Mini Cooper S from 2001 to 2019, specifically the 4B7787H-STD ACL Cooper MINI N12/N14/N16/N18 models. If you're running a .25mm oversized performance rod bearing set, you’re in luck!

So if you’re ready to give your engine the upgrade it deserves, these ACL bearings are a solid choice. They’re built for performance and reliability, making them a great addition to any build.
