What does the STDX sizing mean for these bearings?

The STDX designation means these main bearings are 0.040 inch undersize. This is important if your engine's crankshaft has been machined down by 0.040 inches during a rebuild.

What is the pmax black material used in these bearings?

The pmax black material is King Engine Bearings' racing line compound, known for its strength and ability to withstand higher loads and temperatures often found in performance or heavy-duty applications.

Are these bearings suitable for a stock engine rebuild?

Yes, these bearings are well-built and suitable for stock engine rebuilds, especially if the crankshaft has been machined to the STDX size. The pmax black material also offers improved durability over standard bearings.

Product Details

If you're rebuilding the bottom end of your Ford 370, 429, or 460 16V OHV engine, a solid set of main bearings is crucial. This main bearing set from King Engine Bearings is built for these big Ford V8s, offering a durable solution for your rebuild. These bearings are designed to handle the demands of these engines, whether for street use or more spirited applications.

King Engine Bearings uses their pmax black material for this racing line set, which is known for its strength and ability to perform under pressure. The STDX sizing indicates these are 0.040 inch undersize bearings, important to note if you're machining your crankshaft. This means they are designed to fit a crankshaft that has been ground down by 0.040 inches to ensure a fresh, perfectly sized surface for the new bearings.

This set fits a wide range of Ford vehicles from the late 1960s through the 1990s, including models like the Ford F-250, E-350 Econoline, and Gran Torino. Make sure to check the full fitment list to confirm compatibility with your specific application.
