Collection: Main Bearings

Nothing shreds an expensive bottom end faster than a spun main bearing. Your main bearings are the only thing standing between a screaming crankshaft and catastrophic metal-on-metal destruction. Whether you’re dropping in standard replacements for a reliable OEM rebuild or upgrading to heavy-duty, coated race bearings for a high-boost, high-RPM monster, we’ve got the hardware to survive massive loads. Built for cars, heavy-hauling trucks, and rowdy powersports rigs, our premium main bearings deliver the professional-grade load capacity needed to maintain that critical oil film when things get violent. Dial in your exact clearances, torque those saddles to spec, and hammer the throttle with confidence.
