ACL Race Series Rod Bearing Set for Nissan TD42 4169cc Inline 6 Diesel STD High Performance - 6B2966HX-STD

If you're diving into the world of high-performance engines, you’ll want to check out the ACL Race Series Engine Bearings. These aren’t just any bearings; they’re crafted with a unique blend of design, metallurgy, and engineering that really stands up to the demands of high RPM conditions. Whether you’re working on a 4, 6, or 8-cylinder setup, these bearings have got your back.

What sets these bearings apart? For starters, they feature a high-strength overlay plate that’s thinner than most, which means better fatigue resistance when you’re pushing your engine to the limit. And let’s not forget the hardened steel backs on all rod bearings. This isn’t just for show; it enhances support for the bearing lining and keeps everything snug in the housing. You want your bearings to stay put, right?

Another cool thing is the increased crush, which really helps with bearing retention. No one wants to deal with bearings that shift under pressure. Plus, ACL has eliminated flash plating on the back of these bearings, which improves heat transfer. That’s crucial for keeping your engine cool under heavy loads and ensuring a solid grip between the bearings and their housing.

When you’re revving up, you’ll appreciate the increased eccentricity designed to handle bore distortion at high RPMs. This helps in forming those all-important hydrodynamic oil films that keep everything lubricated. And if you’re worried about oil flow, the 3/4 grooved main bearings are optimized to maximize load-carrying surface area and ensure your conrod bearings get all the oil they need.

Consistency is key in performance builds, and these bearings deliver with tight wall tolerances that help maintain those crucial clearances. Plus, they’ve got enlarged ID chamfers where necessary to fit those larger fillet radii on performance crankshafts. It’s the little details that make a big difference.

In terms of specifications, these ACL Race Series engine bearings are built to withstand the rigors of higher RPM conditions. They come in sizes STD, .025, and .25, so you can find the right fit for your setup. For instance, the 6B2966HX-STD is a solid choice for the Nissan TD42, a 4169cc inline 6 diesel engine, and it even offers extra oil clearance for those pushing the limits.

In short, if you’re serious about performance, these bearings are worth considering. They’re tough, reliable, and designed to keep your engine running smoothly even when the revs are high.
