What does '.025 undersize' mean for these bearings?

This means the bearings are manufactured to be slightly smaller than the standard size. They are intended for use with a crankshaft that has been machined down by 0.025 inches to ensure the correct oil clearance and fit.

What is the main purpose of conrod bearings?

Conrod bearings sit between the connecting rod and the crankshaft. Their main job is to reduce friction and wear, allowing the crankshaft to rotate smoothly while maintaining proper oil pressure within the engine.

Are these bearings sold individually or as a set?

This product is sold as a set, providing all the necessary conrod bearings for your engine rebuild.

Product Details

You get a full set of conrod bearings in this kit, which means one box handles the critical internal engine work. These are ACL bearings, sized at .025 undersize, specifically made for the 2000-2005 Kawasaki ZX1200 Ninja ZX-12R. When you're rebuilding or refreshing the engine on your ZX-12R, getting the bearing clearances just right is crucial for oil pressure and the longevity of your motor.

ACL has been around for a while, and these bearings are well-built for the job. The .025 undersize means they're meant to be paired with a crankshaft that's been machined down by .025 inches. This ensures a tight, proper fit that maintains the correct oil clearance, which is essential for preventing premature wear and ensuring your engine runs smoothly. Installing these bearings is a key step in any performance engine build or repair where the crankshaft has been reconditioned.
