If you’re looking to push your ride to the next level, you’ll want to check out these ACL Race Series Engine Bearings. They’re not just your average bearings; they’re crafted with a killer mix of design and metallurgy that really stands up to the demands of high-performance driving. Whether you’re revving up a 4, 6, or 8-cylinder engine, these bearings are built to handle those higher RPMs without breaking a sweat.
What sets these bearings apart? For starters, the high-strength overlay plate is thinner than what you might find elsewhere, which means improved fatigue properties. Trust me, that’s a big deal when you’re pushing your engine hard. Plus, all the rod bearings come with hardened steel backs. This not only supports the bearing lining but also helps keep everything locked in place within the housing.
One of the standout features is the increased crush, which really helps with bearing retention. You don’t want your bearings shifting around when you’re hitting those high RPMs, right? And speaking of high RPMs, the elimination of flash plating on the back of the bearings is a game changer. It enhances heat transfer and maximizes grip between the bearings and the housing, which is crucial when you’re racing or just pushing your limits on the street.
These bearings also have increased eccentricity. What does that mean for you? It compensates for any bore distortion at high speeds and helps in forming those hydrodynamic oil films that keep everything running smoothly. The 3/4 grooved main bearings are designed to optimize the load-carrying surface area and ensure that oil flows freely to the conrod bearings. You’ll appreciate the tight, consistent wall tolerances too, as they help maintain those all-important clearances.
And if you’ve got a performance crankshaft, the enlarged ID chamfers on the bearing edges will accommodate those larger fillet radii without a hitch.
As for the specs, these bearings come in sizes like STD, .025, and .25. You’ll find standard oil clearance with identical halves, crafted from tri-metal hardened steel backs. They fit a range of standard shaft sizes, with a minimum of 1.9677" (49.980 mm) and a maximum of 1.9685" (50.000 mm). The tunnel sizes range from 2.0876" (53.025 mm) to 2.0884" (53.045 mm), and the overall length is 0.661" (16.80 mm) with a max wall at the crown of 0.0591" (1.500 mm).
These bearings are a perfect fit for models like the Ford Escape from 2001 to 2018 and the Ford Focus from 2000 to 2018. If you’re running a Ford/Mazda (L3) Duratec 2.3L, you’ll want to grab the .25mm oversized high-performance rod bearing set. Trust me, you won’t regret it when you feel the difference on the road or track.
