If you're diving into the world of high-performance engines, you’ve probably heard about ACL Race Series Engine Bearings. These aren’t just any bearings; they’re crafted with a solid mix of smart design, top-notch metallurgy, and some serious engineering know-how. Built to handle the demands of higher RPMs, these bearings are a must-have for anyone looking to push their engine to the limit.

What makes these bearings stand out?

• First off, the overlay plate is high-strength but thinner, which means it can take a beating without giving up. This design helps with fatigue resistance, so you can keep your foot on the gas without worrying about wear and tear.
• All rod bearings come with hardened steel backs. This isn’t just for show; it gives the bearing lining extra support and keeps everything snug in the housing.
• They’ve cranked up the crush factor to ensure the bearings stay put where they belong. No one wants their bearings moving around when the engine’s revving high.
• Forget about flash plating on the back. This feature has been axed to boost heat transfer, which is crucial for keeping things cool when you’re pushing your engine hard.
• With increased eccentricity, these bearings can handle the bore distortion that happens at high RPMs. This is key for forming those hydrodynamic oil films that lubricate and protect your engine.
• The main bearings are 3/4 grooved, which optimizes the load-carrying surface area and improves oil flow to the conrod bearings. That means better performance all around.
• You’ll appreciate the tight, consistent wall tolerances that help maintain clearances, ensuring everything runs smoothly.
• And let’s not forget the enlarged ID chamfers on the edges where necessary. This accommodates those larger fillet radii on performance crankshafts, making installation a breeze.

Specifications:

• These bearings are designed for dependability, especially under high RPM conditions. You can trust them to stand up to the rigors of performance driving.
• The combination of design and engineering really delivers what you want from high-performance parts.
• Available sizes include STD, .025, and .25, so you can choose what fits your setup best.

For those running a VW or Audi VR6 engine (2792cc, 2861cc, 3189cc, or 3597cc), the 6B5530H-.025 set is a solid choice. It’s an oversized high-performance rod bearing set that will keep your engine running strong, even when you’re pushing the limits. If you’re serious about performance, these bearings are worth considering.
