One of the most influential and popular monster trucks of all time, Grave Digger, uses HP bearings from King Engine Bearings.
Made of bi-metal, aluminum silicon alloy, HP bearings feature a 40 Vickers hardness that resists traditional overlay migration and extrusion, making them ideal for the demands of high-load, short-duration race environments such as drag racing, tractor pulls and monster trucks, according to a press release.
Grave Digger is a team of monster trucks that race in the USHRA Monster Jam series across the U.S. and around the world. Their flagship driver is creator Dennis Anderson.
“I’ve used King Engine Bearings for over 10 years,” said Anderson. “I will never run another brand in my motors because King outlasts them all.”
Grave Digger puts HP Bearings to the test with its alcohol-injected, 540-ci Merlin engine that produces 1,465 maximum horsepower. At 10,400 lbs., Grave Digger makes 1,200 pounds of torque and reaches a maximum rpm of 8,400.
King produces high performance engine bearings for circle track, drag racing, monster trucks, tractor pulls, off-road and off-shore racing applications.
