ACL GTR Standard Sized High Performance Main Bearing Set (Version 1 Block)

You get a full set of standard sized main bearings in this kit, which means one box handles the whole engine rebuild. These ACL bearings are made for the Nissan GT-R, specifically for the Version 1 block. When you're rebuilding or refreshing your engine, the main bearings are critical for keeping the crankshaft spinning smoothly and true within the engine block. Using the right bearings ensures proper oil clearance and reduces friction, which is key for engine longevity and performance.

ACL has a good reputation for making well-built engine components. These bearings are designed to meet the demands of the GT-R's high-performance engine. They are a standard size, so they're meant to be used when the crankshaft journals are still within factory specifications. If your crankshaft has been machined undersize, you'd need a different bearing size.

This set includes all the main bearings you'll need for your GT-R engine. Make sure to follow the manufacturer's installation instructions carefully, as proper torque and oiling are essential for these components.
