What is the difference between main bearings and rod bearings?

Main bearings support the crankshaft within the engine block, while rod bearings connect the connecting rods to the crankshaft. This kit specifically contains the main bearings needed for your engine's bottom end.

Do I need to measure my crankshaft before ordering standard size bearings?

Standard size bearings are meant to fit a crankshaft that is within factory specifications. If your crankshaft has been previously machined or is out of round, you may need to measure it and order undersize bearings instead. Always check your crankshaft's condition during an engine rebuild.

What else might I need when installing these main bearings?

When installing main bearings, you'll typically need assembly lube to coat the bearings and crankshaft journals. You'll also need a torque wrench to tighten the main bearing caps to the manufacturer's specifications, and potentially a service manual for detailed instructions.

Product Details

You get a full set of standard size race main bearings in this kit, which means one box handles the critical bottom-end rebuild for your Lexus or Toyota V8. These bearings are built by ACL, a well-known name in engine components, and are designed for engines that see harder use than a daily driver. If you're rebuilding a 1UZFE engine for performance or just want a solid replacement for a worn-out set, these are a good choice.

These main bearings are made to the original equipment specifications for size, so they'll fit right into your prepared crankshaft and block. ACL uses a specific material composition that's well-suited for the higher loads and temperatures that performance or high-mileage engines can experience. They are a popular option when you're looking for a reliable bearing that won't break the bank, especially when you're already deep into an engine build or overhaul.

This set is for the main bearings only. Make sure to check your crankshaft and block surfaces for any damage or wear before installation, and always follow the manufacturer's recommended torque specifications and assembly procedures. If you're unsure about the process, it's always best to consult a professional mechanic.
