ACL Engine Bearings Main Bearing Set for Nissan L16E/L18E 68-74, STD Size, .001 Oil Clearance - 5M1172HX-STD

If you're diving into the world of high-performance engines, you know that the right engine 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 designed for those who push their machines to the limit, handling higher RPMs with ease. Whether you've got a 4, 6, or 8-cylinder setup, these bearings are tailored to fit many popular applications, including the Nissan L16E/L18E engines.

What sets these bearings apart? Well, for starters, the high strength overlay plate is thinner, which actually boosts its fatigue resistance. This means they can take a beating without giving up. Plus, they've got hardened steel backs on all rod bearings. This little feature is a game-changer for keeping the bearing lining supported and ensuring they stay put in the housing.

And let’s talk about crush – these bearings come with increased crush for better retention. This is crucial when you're revving high and need that extra grip. Speaking of grip, the elimination of flash plating on the back helps with heat transfer, so you won't have to worry about overheating when you're pushing your engine hard.

One thing I really appreciate is the increased eccentricity. This compensates for any bore distortion that might happen at high RPMs, making sure that hydrodynamic oil films form properly. You’ll also find 3/4 grooved main bearings here, which optimize the load-carrying surface area and oil flow to the conrod bearings. It’s these details that help keep everything running smoothly.

Consistency is key, and these bearings have tight wall tolerances to help you maintain those all-important clearances. Plus, they feature enlarged ID chamfers on the edges where needed, accommodating the large fillet radii on performance crankshafts. It’s the kind of thoughtful engineering that makes a real difference when you’re racing or just enjoying a spirited drive.

In terms of size, you're looking at the 5M1172HX-STD set for the Nissan L16E/L18E, with an oil clearance of .001. If you want dependability under pressure, these ACL Race Series engine bearings have got your back. They’re built for those who demand performance and need parts that can keep up with their passion.
