ACL Aluminum Rod Bearing Set

If you're serious about performance, you know that the right engine bearings can make all the difference. The ACL Race Series Engine Bearings are where cutting-edge design meets solid engineering, and trust me, they???re built to handle the heat when you're pushing your ride to the limits. Whether you???re working with a 4, 6, or 8-cylinder engine, these bearings are designed for those high RPM situations that make your heart race.

What sets these bearings apart? For starters, they boast a high-strength overlay plate that???s thinner than what you might find elsewhere, which really helps with fatigue resistance. That means when you???re revving your engine, these bearings are less likely to let you down. The hardened steel backs on all rod bearings provide extra support for the lining and help keep everything snug in its housing???no one wants bearings that shift around when the going gets tough.

And let???s talk about crush. These bearings have increased crush, which means they stay put better, providing improved retention. Plus, they???ve done away with flash plating on the backs, which not only enhances heat transfer but also maximizes the grip between the bearings and the housing. You want your components to work together seamlessly, right? This is how you achieve that.

When you???re running at high RPMs, bore distortion can be a real pain. That???s why these bearings have increased eccentricity to help counteract that issue and assist in creating those all-important hydrodynamic oil films. And if you???re worried about oil flow, the 3/4 grooved main bearings are designed to optimize load-carrying surface area and ensure oil gets to where it???s needed most???your conrod bearings.

Consistency is key in performance, and these bearings come with tight wall tolerances to help maintain those clearances you???re after. Plus, the enlarged ID chamfers on the edges accommodate larger fillet radii on performance crankshafts, which is just one more way ACL has thought of everything.

As for the specs, they???re pretty solid too. You can get these bearings in sizes STD, .025, and .25, with standard oil clearance. They???re made from a blend of aluminum, tin, and silicon, ensuring durability without sacrificing performance. The minimum standard shaft size is 1.888 inches, and they fit a range of Nissan models from the NX (1991-1996) to the Pulsar (1987-2005) and even the Silvia S15 (1999-2002). If you???re running the SR20DE/DET engine, these .25 oversized aluminum rod bearings are a perfect match.

So, if you???re gearing up for your next build or just looking to replace some worn-out components, these ACL Race Series Engine Bearings might be just what you need to keep your engine running strong and ready for whatever you throw at it.
