ACL Honda/Acura Race Series Rod Bearing Set 4B1972HXD-STD for 02-06 Acura RSX 2.0L/2.4L K20A2/K24A
$51.95

If you’re looking to push your engine’s performance to the next level, the ACL Race Series Engine Bearings are where it’s at. These aren’t just your run-of-the-mill bearings; they’re crafted from a unique blend of design, metallurgy, and engineering that really delivers when it counts. I've had my hands on these for a while now, and let me tell you, they’re built to handle those high RPMs without breaking a sweat.

What sets these bearings apart? For starters, the high-strength overlay plate is thinner, which means it’s got improved fatigue properties. This is crucial when you’re really pushing your engine to its limits. Plus, every rod bearing comes with hardened steel backs. This isn’t just for show; it gives the bearing lining better support and helps keep everything snug in 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 out on the track or hitting those back roads. And they’ve eliminated flash plating on the back of the bearings, which is a game changer for heat transfer. This means you get better grip between the bearings and their housing, which is essential for performance.

When you're revving up, the increased eccentricity helps compensate for any bore distortion, ensuring you get those hydrodynamic oil films just right. And if you’re worried about oil flow, the 3/4 grooved main bearings are designed to optimize the load-carrying surface area, so oil gets to the conrod bearings like it should. Consistent wall tolerances are another bonus, helping you maintain those critical clearances.

Now, let’s talk specs. These bearings come in standard size, with an oil clearance of +0.001", which gives you that little extra room to breathe. The material is tri-metal with hardened steel backs, ensuring durability. They fit a range of applications, including the Acura RSX from 2002 to 2006 with a 2.0L or 2.4L engine (K20A2/K24A)—so you know they’re versatile.

  • Min Std Shaft Size: 1.889in / 47.98 mm
  • Max Std Shaft Size: 1.8898in / 48 mm
  • Min Std Tunnel Size: 2.008in / 51.004 mm
  • Max Std Tunnel Size: 2.0088in / 51.024 mm
  • Max Wall at Crown: 0.0585in / 1.487 mm
  • Max Overall Length: 0.6063in / 15.40 mm

So if you’re serious about getting the most out of your engine, these bearings are worth considering. They’ve got the features and the durability to keep your ride running strong, whether you’re on the street or the track. Trust me, you won’t regret it.
