TFC – Top Fuel/Pro Mod
Top Fuel Line represents the culmination of the innovative & goal-oriented research and production from King.
KING'S TECHLAB - EXCEED AND EXCEL
TechLab is our starting point for exploring and developing new technologies. It’s where our new products and features are designed, tested and validated.
Our TechLab R&D culture focuses on constant analysis of what can be done to support ever increasing race engine loads, and how to improve bearing durability.
One of those technologies is pMax-Black™.
pMaxBlack™ combines a unique tri-metal structure with advanced surface processes to deliver superior load capacity.
Top Fuel Bearings
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.
