ACL Toyota 6 5MGE/7MGE 0.50mm Oversized Main Bearing Set 1984-1998 Trimetal - 7M1165-.50

If you’re diving into the world of high-performance engines, you know that the right bearings can make all the difference. That’s where the ACL Race Series Engine Bearings come into play. These aren’t just any bearings; they’re crafted with a unique blend of design, metallurgy, and engineering that really speaks to what drivers expect when pushing their engines to the limit.

These bearings are built to handle the heat—literally. With a high-strength overlay plate that’s thinner than what you might find on standard bearings, you get improved fatigue properties that are essential for those higher RPM conditions. Trust me, when you’re revving up, you want something that can take the pressure without flinching.

Now, let’s talk about the rod bearings. They’ve got hardened steel backs, which helps support the bearing lining and keeps everything snug in the housing. You’ll notice the increased crush too; it really helps with retention, so you don’t have to worry about any slippage when you’re pushing your ride hard.

Heat transfer? They’ve nailed that as well. By eliminating flash plating on the back of the bearings, you get better heat dissipation, which means more reliable performance. Plus, the increased eccentricity is a game-changer, compensating for any bore distortion at high RPMs and allowing for the formation of hydrodynamic oil films. This is crucial for maintaining that smooth operation.

And for those of you running performance crankshafts, the enlarged ID chamfers on the bearing edges accommodate larger fillet radii, which is a thoughtful touch. You’ll also appreciate the 3/4 grooved main bearings—this design optimizes the load-carrying surface area and ensures oil flows seamlessly to the conrod bearings.

When it comes to specifications, you’ve got options. These bearings come in sizes like STD and 00.5, making them a solid choice for OEM engines and perfect for replacement applications. Made from tri-metal, these Duraglide bearings have been the go-to for many engine rebuilds, and for good reason.

So if you’re working on a Toyota 6 5MGE or 7MGE, check out the 7M1165-.50 ACL oversized main bearing set for years 84-98. These bearings are designed to keep your engine running smoothly, even when you’re pushing it to the max.
