TOP FUEL / PROMOD

Specially Designed For Over 10,000 Horsepower

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 / PROMOD

Ultra high horsepower developed in 500 cubic inch Top Fuel engines can cause havoc with regular engine bearings in a matter of seconds. Under heavy loads, engine bearings are required to resist fatigue and deformation. Any deformation or fatigue can cause the oil film to become weak and break down, allowing contact between the bearing and crankshaft surfaces.

King TFC bearings have a unique metallurgic structure developed specifically for Top Fuel, Funny Car, Pro Mod and similar applications. TFC features a polymer composite matrix over strengthened Babbitt, and a special ductile bronze intermediate layer over a high strength steel platform. King TFC bearings are designed to withstand the metal-to-metal contact and extreme loading from 10,000 HP Top Fuel engines.

Top Fuel engines can cause havoc with regular engine bearings in a matter of seconds. King developed TFC bearings with a unique metallurgic structure specifically for Top Fuel, Funny Car, Pro Mod and similar ulta-high horsepower applications.

FEATURED TOP FUEL / PROMOD BEARINGS

TOP FUEL

Top Fuel dragsters and Funny Cars are the fastest drag race vehicles in the world. With nitromethane as a fuel and 500 cubic inches of displacement, they develop over 10,000 horsepower. They are capable of reaching speeds of 335mph in 3.6 seconds during a run of 1,000 ft.

PROMOD

Pro Mod race cars are 250+ mph door slammers running on injected nitrous/high octane racing fuel or supercharged and fueled with methanol. They are the fastest class of drag cars with working doors. Pro Mods are purpose-built race cars cloaked in replica street car bodies ranging in style from the 1930’s to the present day. They can cover the quarter mile in under 6 seconds.
