What is the STDX size for these bearings?

The STDX size indicates a specific clearance for the connecting rod bearings. This size is often used in performance applications or when the crankshaft journals have been machined undersize during a rebuild.

Why do these bearings have a polymer coating?

The polymer coating is a racing line feature designed to handle higher loads and reduce friction. It offers extra protection for the bearing surface and crankshaft journal, especially during the critical break-in period of a new or rebuilt engine.

What else is needed for installing these bearings?

Proper installation requires precise measurement of crankshaft journal diameter and connecting rod bore. You will also need assembly lube, torque wrenches, and potentially a service manual for specific torque values and procedures for your vehicle.

About this part

Product Details

If you're rebuilding the engine in your 1991-2002 Infiniti G20 with an SR20DE or SR20DET engine, a fresh set of connecting rod bearings is critical. These bearings sit between the crankshaft and the connecting rod, allowing the rod to spin smoothly while handling immense pressure. Worn bearings can lead to serious engine damage, so replacing them during an engine build is a must.

This set from King Engine Bearings features a polymer coating, which is a racing line application designed to handle high loads and reduce friction. This coating helps protect the bearing surface and the crankshaft journal, especially during the critical break-in period of a freshly rebuilt engine. They are built to fit the SR20DE/DET RWD 2.0L engine and come in the STDX size, which is often used for performance builds or when crankshafts have been reconditioned.

When you're putting an engine back together, especially one that's been modified or is being refreshed, using well-built internal components like these bearings is key to a reliable build. Make sure to follow the manufacturer's lubrication and clearance specifications during installation to ensure these bearings perform as intended.
