Kings Racing | Main Bearings | Ford Fiesta ST150 Duratec 2.0L
DESCRIPTION
Forged not just from metal, but from a singular obsession born in 1960: to create the undisputed pinnacle of engine bearings. King Engine Bearings achieves this not by following industry standards, but by relentlessly rewriting them.
King’s mastery begins with specialization, channeling six decades of focus into every component. This depth of knowledge, honed in the crucibles of aviation and championship racing, is engineered into every aftermarket bearing they produce, including this 5-pair Main Bearing set.
The proof is in the proprietary process. King reinvented manufacturing from the ground up, controlling every micron from concept to finished product under one roof. This obsessive control enables a symphony of precision: a Silicone Aluminum alloy is machined to a exacting 2.504mm thickness and 19.101mm width, ensuring a perfect, durable interface between the 57.018 – 57.036mm housing and the 51.979 – 51.999mm crankshaft.
Each bearing must survive a gauntlet of rigorous quality checkpoints, a stringent system ensuring that only perfection reaches your hands. The result is more than a component; it is a foundation of trust. This bearing set embodies the quiet, unwavering confidence of the King legacy—where advanced design, premium materials, and self-forged manufacturing excellence converge to deliver not just a part, but complete satisfaction.
