If you're pushing your engine to the limit, you know that the right bearings can make all the difference. The ACL Race Series Engine Bearings are engineered to handle the demands of high-performance driving, whether you're on the track or just enjoying a spirited drive. These aren’t your run-of-the-mill bearings; they’re designed to withstand those higher RPMs that come with serious power.

What sets these bearings apart? For starters, the high-strength overlay plate is thinner, which means it can better handle fatigue without compromising durability. That’s crucial when you’re really pushing your engine. And let’s talk about the hardened steel backs on the rod bearings—they provide solid support for the lining and help keep everything snug in the housing, which is essential for reliability.

One of the standout features is the increased crush, which enhances bearing retention. You don’t want your bearings shifting around when you’re at full throttle. Plus, they’ve eliminated flash plating on the back, which not only improves heat transfer but also maximizes the grip between the bearings and their housing. This means better performance and less risk of failure under pressure.

When you're revving high, bore distortion can be a real issue. That’s where the increased eccentricity comes into play, helping to create those all-important hydrodynamic oil films that keep everything running smoothly. And those 3/4 grooved main bearings? They’re optimized to improve oil flow to the conrod bearings, ensuring that every part of your engine gets the lubrication it needs.

With tight, consistent wall tolerances, you can maintain your clearances with confidence. Plus, enlarged ID chamfers on the edges accommodate those larger fillet radii on performance crankshafts, making installation a breeze.

Here’s a quick look at the specs: You can choose from sizes like STD, .025, .25, and .50. They feature standard oil clearance and come as identical halves made from tri-metal hardened steel backs. For those who need the exact fit, the minimum standard shaft size is 1.8892 inches and maximum is 1.8898 inches. The tunnel sizes range from 2.008 to 2.0088 inches, and the max wall at the crown is 0.0586 inches.

These bearings fit a variety of popular applications, including:

• Toyota Celica (1982-2005)
• Toyota MR2 (1984-1999, specifically the 4B8366H-.25 ACL Toyota 3SGTE 0.25mm Oversized High Performance Rod Bearing Set)

So if you're looking to upgrade your engine's performance, these ACL Race Series Engine Bearings are worth considering. They’re built for those who demand more from their ride, and trust me, you’ll feel the difference.
