ACL Porsche 930 Turbo H6 .025mm Oversized Rod Bearing Set 1978-1979 - 6B2463H-.025

If you're looking to push your engine's limits, you might want to check out these ACL Race Series Engine Bearings. These aren’t just any bearings; they’re designed with a specific focus on performance, especially for those high RPM situations where you really feel the power of your ride. Whether you’ve got a 4, 6, or 8-cylinder setup, these bearings are crafted to handle the heat and stress that comes with pushing your engine to its limits.

What makes these bearings stand out?

  • First off, the high-strength overlay plate is thinner, which might sound counterintuitive, but it actually improves fatigue properties. Less material means less weight, and that’s a win for performance.
  • All the rod bearings come with hardened steel backs. This isn’t just for show; it supports the bearing lining better and helps keep everything snug in its housing.
  • They’ve cranked up the crush on these bearings too, which helps with retention—no one wants a bearing that’s going to move around when the engine’s screaming.
  • Forget about flash plating on the backs; these bearings are designed for better heat transfer. This means they can dissipate heat more effectively, maximizing grip in the housing.
  • Increased eccentricity? Yep, that’s included too. It helps counteract bore distortion at high RPMs and aids in forming those all-important hydrodynamic oil films.
  • The 3/4 grooved main bearings are a nice touch, optimizing the load-carrying surface area and ensuring oil flows smoothly to the conrod bearings.
  • With tight and consistent wall tolerances, you can maintain those clearances that matter when you’re revving high.
  • And let’s not forget the enlarged ID chamfers on the edges where needed, perfect for accommodating those larger fillet radii on performance crankshafts.

Specifications:

  • These bearings are built to last under higher RPM conditions, giving you the reliability you need when you’re pushing your engine.
  • With sizes available in STD, 0.25, and .25, you can find the right fit for your setup.

Fitment:

These bearings specifically fit the Porsche 930 from 1975 to 1989, particularly the 6B2463H-.025 model. If you’re rocking a 78-79 Porsche 930 Turbo with an H6 engine, this .025mm oversized high-performance rod bearing set is just what you need to keep things running smoothly at those higher RPMs.
