Top Fuel/Pro Mod

King factory applied nano-composite polymer coating – With no added thickness!

Top Fuel Line represents the culmination of the innovative and goal oriented research and production from King Engine bearings House.

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. In those applications, 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 sigificant 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

Top Fuel/Pro Mod benefits:
  • 24% greater load capacity
  • 17% more fatigue resistance
  • Compatible with all crankshafts
