What does '0.50mm Oversize' mean for these bearings?

This means the bearings are slightly larger in diameter than standard factory bearings. They are designed to be used when the crankshaft journals have been machined down by 0.50mm to correct for wear or to achieve a specific build clearance. Using the correct oversize bearing is crucial for proper oil clearance and engine longevity.

Are these bearings suitable for a stock engine rebuild?

While these are high-performance bearings, they can be used in a stock rebuild if the crankshaft has been machined to the 0.50mm oversize specification. If your crankshaft is still at standard size, you would need a standard size bearing set.

What other parts are typically needed when replacing rod bearings?

When replacing rod bearings, it's common practice to also replace the main bearings, piston rings, and engine oil. It's also essential to have the crankshaft professionally measured and machined if necessary, and to clean all engine components thoroughly before reassembly.

About this part

Product Details

ACL has been making engine bearings for decades, and this high-performance rod bearing set for your VG30DETT engine is one of their staples. When you're rebuilding or refreshing an engine, especially one that sees hard use, the rod bearings are critical. They sit between the connecting rod and the crankshaft, handling immense forces and allowing smooth rotation. This set is specifically sized at 0.50mm oversize, meaning it's intended for crankshafts that have been machined down by 0.50mm to correct for wear or to achieve a specific build clearance.

These aren't just standard replacement bearings; they're built with performance in mind. ACL uses a specialized overlay material that's designed to handle higher loads and temperatures than stock bearings. The precision machining ensures a consistent oil clearance, which is vital for proper lubrication and preventing premature wear. If you're building a performance engine or repairing a worn one, getting the right bearing size and quality is key to a long-lasting, reliable build.

This set includes rod bearings for a complete VG30DETT engine. Always refer to your vehicle's service manual or your engine builder's specifications for the correct bearing size and installation procedures. Proper installation, including correct oil clearances and torque specifications, is essential for the longevity of your engine.
