What does the 'STDX' size mean for these main bearings?

The 'STDX' designation indicates that these bearings are 0.040 inches undersize. This is important if your engine's crankshaft has been ground undersize during a rebuild to correct wear or runout.

Why are the '6 Lower Flanges' important for Top Fuel engines?

The six lower flanges are a design feature that helps to increase the surface area and rigidity of the main bearing. This provides better support and load distribution for the crankshaft, which is essential for handling the extreme forces in Top Fuel racing engines.

What is the typical lifespan or warranty for these bearings?

King Engine Bearings are known for their durability in high-stress applications. Specific warranty details are best obtained directly from the manufacturer, but these bearings are built to withstand demanding racing conditions.
