What is the main purpose of these main bearings?

Main bearings support the crankshaft within the engine block, allowing it to rotate with minimal friction. They are essential for reducing wear and maintaining proper oil clearance in the engine's bottom end.

Are these bearings suitable for a stock GT-R engine?

Yes, these are standard sized bearings designed as a direct replacement for stock specifications. They are well-suited for both stock and performance-oriented GT-R engines, provided the crankshaft journals are within factory tolerances.

What does 'Version 3 Block' mean for fitment?

The 'Version 3 Block' designation indicates these bearings are specifically designed for a particular revision or design of the GT-R engine block. This ensures proper fit and function within that specific block configuration.

Product Details

ACL has been making engine bearings for decades, and this standard sized main bearing set for your Nissan GT-R (V3 block) is one of their staples. These bearings are crucial for keeping your engine's crankshaft spinning smoothly within the engine block. They sit between the crankshaft journals and the main bearing caps, reducing friction and wear in a high-performance application like the GT-R's VR38DETT engine.

This set is built to handle the demands of a performance engine. ACL uses a tri-metal overlay material that's known for its strength and ability to embed debris, helping to protect your crankshaft. The standard sizing means they're a direct replacement for your original bearings, assuming your crankshaft journals are still within factory specifications. If your engine has seen significant mileage or performance modifications, it's always a good idea to measure your journals to ensure they haven't worn out of tolerance.

When you're rebuilding or refreshing the bottom end of your GT-R, a well-built set of main bearings like these from ACL is a solid choice. They are designed to provide consistent oil clearance and support for the crankshaft under high loads.
