ACL Toyota 3TC P-Series 0.20 Oversized Rod Bearing Set 4B1686P-20 for High Performance - 4B1686P-20

If you're diving into the world of performance engines, you know that the right bearings can make a world of difference. That’s where the ACL Race Series Engine Bearings come into play. These aren't just any bearings; they’re designed for those who push their engines to the limit, whether you’re wringing out every RPM on the track or just want your daily driver to run a bit smoother.

What sets these bearings apart? For starters, they feature a high-strength overlay plate that’s thinner than what you might find on standard bearings. This isn’t just about saving weight; it’s about enhancing fatigue resistance when your engine is screaming at high RPMs. Trust me, when you're pushing hard, you want every edge you can get.

All the rod bearings come with hardened steel backs, which means they provide solid support for the bearing lining. This helps keep everything in place, so you don’t have to worry about the bearings shifting in the housing under stress. Plus, they’ve got increased crush for better retention—no one wants to deal with a bearing that’s not seated properly.

One of the cool features is the removal of flash plating on the back of these bearings. This isn’t just a design choice; it actually helps with heat transfer, which is crucial when you’re pushing your engine. Better heat management means better performance. And with increased eccentricity, these bearings compensate for any bore distortion you might see at high RPMs, ensuring that hydrodynamic oil films can form properly.

Let’s talk about the 3/4 grooved main bearings. This design optimizes the load-carrying surface area and improves oil flow to the conrod bearings, which is essential for keeping everything lubricated and running smoothly. Plus, with tight wall tolerances, you can maintain consistent clearances, which is key for performance builds.

Lastly, the enlarged ID chamfers on the edges accommodate larger fillet radii on performance crankshafts. So, if you’re building something serious, these bearings are designed to fit right in without any fuss.

For those working on a 1985 Toyota 3TC, this 4B1686P-20 ACL P-Series 0.20 Oversized Rod Bearing Set is a perfect match. It’s got everything you need to keep your engine running strong, even when you’re pushing it hard. If you’re serious about performance, these bearings are worth a look.
