If you're diving into high-performance builds, you know that engine bearings can make or break your setup. The ACL Race Series Engine Bearings are not just another set of bearings; they’re crafted with a unique blend of design, metallurgy, and engineering that really stands out. These bad boys are built to handle those higher RPMs that come with pushing your engine to its limits. Whether you're working on a 4, 6, or 8-cylinder engine, you’ll find a fit that suits your needs.
What Makes These Bearings Special?
- First off, the high-strength overlay plate is thinner, which means better fatigue resistance. You want your bearings to last, right?
- They come with hardened steel backs on all rod bearings, providing solid support for the bearing lining and keeping them snug in the housing.
- With increased crush, these bearings hang on tight, ensuring they don’t go anywhere when the pressure’s on.
- No flash plating on the back means better heat transfer. This helps keep things cool and maximizes grip between the bearings and the housing.
- Increased eccentricity helps tackle bore distortion at high RPMs, which is crucial for forming those hydrodynamic oil films.
- The 3/4 grooved main bearings are designed to optimize load carrying surface area and oil flow to the conrod bearings. More oil flow means better lubrication.
- Consistent wall tolerances mean you can maintain those clearances you’re after, which is key when you’re tuning for performance.
- Plus, they’ve got enlarged ID chamfers on the edges to fit those performance crankshafts with larger fillet radii.
