If you're diving into the world of high-performance engines, you know that the right bearings can make all the difference. The ACL Race Series Engine Bearings are a solid choice for anyone who's pushing their ride to the limits. These bad boys are engineered to handle the kind of RPMs that would make lesser bearings cringe. Seriously, whether you've got a 4, 6, or 8-cylinder setup, these bearings are designed to keep your engine running smoothly under pressure.

What sets these bearings apart? Well, for starters, they've got a high-strength overlay plate that’s thinner than what you might find in standard bearings. This isn’t just for show; it actually improves fatigue properties, which means they can take a beating without giving up. Plus, the hardened steel backs on all the rod bearings offer extra support for the lining, helping to keep everything snug in its housing. You won't have to worry about them shifting around when things get intense.

Another cool feature is the increased crush, which enhances bearing retention. This means they’re less likely to slip out of place when you’re revving high. And if you’re concerned about heat, they’ve eliminated flash plating on the back, which allows for better heat transfer. That’s crucial when you’re pushing your engine hard; you want those bearings to stay cool and perform at their best.

These bearings also have increased eccentricity. What does that mean for you? It compensates for any bore distortion that happens at high RPMs and helps in forming those all-important hydrodynamic oil films. And if you’re running a performance crankshaft, the enlarged ID chamfers on the edges are designed to accommodate larger fillet radii, so you won’t have any surprises when you’re putting everything together.

Now, let’s talk specs. The 3/4 grooved main bearings are engineered to optimize the load-carrying surface area and ensure oil flows smoothly to the conrod bearings. With tight, consistent wall tolerances, you can maintain those clearances that are so crucial for performance. Plus, the hardened steel backing is there to maintain crush under high loads and temperatures, so you know these bearings are built to last.

In terms of fitment, these bearings are compatible with a range of vehicles, including:

• Lotus Elise (1996-2018)
• Lotus Exige (2004-2018)
• Toyota Celica (1982-2005) - specifically the 4B1856A-.50 ACL Toyota 2ZZGE 1796cc 0.50mm Oversized Rod Bearing Set (00+)

If you have any questions or need help figuring out what you need, don’t hesitate to reach out. These bearings are a solid investment for anyone serious about their engine performance.
