ACL Race Series .25mm Oversized High Performance Rod Bearing Set for Nissan TD42 4169cc Inline 6 Diesel - 6B2966H-.25

If you're looking to push your engine to its limits, the ACL Race Series Engine Bearings are where it's at. These aren't just any bearings; they’re crafted with a unique blend of design, metallurgy, and engineering that really sets them apart. I’ve used these bearings in my own setup, and let me tell you, they’re built to handle the high RPMs that come with serious driving.

One of the standout features is the high-strength overlay plate. It’s thinner than what you might find in standard bearings, which means less weight and better fatigue resistance. That’s crucial when you’re revving hard. Plus, the hardened steel backs on all the rod bearings really add to the support for the bearing lining. This helps keep everything locked in place, even when the engine is screaming.

Speaking of staying put, the increased crush on these bearings means they grip the housing better. And they’ve done away with flash plating on the back, which is a big win for heat transfer. You want your bearings to dissipate heat efficiently, and these do just that while maximizing the grip between the bearings and the housing. It’s all about keeping things cool and tight under pressure.

Another cool detail is the increased eccentricity. This helps compensate for any bore distortion you might encounter at high RPMs, which is essential for forming those hydrodynamic oil films that keep everything lubricated. And don’t forget about the 3/4 grooved main bearings; they optimize the load-carrying surface area and oil flow to the conrod bearings, ensuring you’ve got the best setup possible.

With tight and consistent wall tolerances, you can maintain those clearances without any guesswork. Plus, the enlarged ID chamfers on the bearing edges accommodate larger fillet radii on performance crankshafts, which is a nice touch for those of us pushing the envelope.

To sum it up, these ACL Race Series engine bearings are designed for dependability under the most demanding conditions. They come in sizes like STD, .025, and .25, so you can find the right fit for your ride. For example, the 6B2966H-.25 is perfect for the Nissan TD42 4169cc Inline 6 Diesel, providing that .25mm oversized boost you need for high performance.

In short, if you’re serious about performance and want bearings that can keep up with your ambitions, these are the ones to grab.
