King SI-Series main bearings are recommended for OE applications. These replacement bearings are designed for aftermarket gasoline or diesel engine rebuilding—and performance engines with factory crankshafts. The bearings have an improved crankshaft finish for reducing microscopic ferrite peaks on improperly ground or polished nodular cast iron crankshafts. King SI-Series main bearings feature improved oil clearance to reduce wear and increase engine life, which in turn reduces operating noise, vibration, and excess oil flow. Order the bearing set designed for fitment on your make and model.

King TFC-Series engine main bearings feature a special factory applied nano-composite polymer coating—with no added thickness! The Top Fuel Line represents the culmination of the innovative and goal oriented research and production from King Engine bearings House. These bearings are available for a wide range of vehicles, especially year/make and engine applications from the 1960s and '70s. Additional details: TOP FUEL BEARINGS with K-40 POLYMER COATING: This coating composition was specially designed for engines experiencing continuous metal-to-metal contact, which is characteristic of the extreme loading and conditions found in various categories of drag racing. K-40 is used for Top Fuel, Funny Car, Pro Mod and similar applications—where bearings are required to resist metal-to-metal contact and deformation. Extreme loads cause the oil film to break down, allowing contact between the bearing and crankshaft surfaces. Maintaining low friction, even during the conditions of metal-to-metal contact, is crucial to the life of any engine bearing. King TFC bearings are designed to withstand the loading generated from 10,000 hp Top Fuel engines. TFC winning attributes: * HIGH STREGTH STEEL: able to withstand extreme loads * SPECIAL DUCTILE BRONZE LINING: will not crack under significant plastic deformation caused by high power engine (10,000 hp) * EXTRA THICK BABBIT LINING: strengthened by copper, excellent conformability * K-40 POLYMER LAYER: provides excellent anti-friction and anti-seizure properties during metal-to-metal contact
