Sierra 1500 2014-2018 GMC - Lifetime Warranty Front Wheel Bearing by Kryptonite

The Kryptonite KR6491 Wheel Bearing Hub Assembly is a heavy-duty replacement hub designed for 2014–2018 GMC Sierra 1500 trucks. Engineered to withstand the added stress from leveled and lifted suspensions, oversized wheels and tires, towing, and off-road use, this premium wheel bearing assembly delivers superior durability, steering stability, and long-term reliability over standard replacement hubs.

Unlike generic wheel bearing assemblies, Kryptonite utilizes a tapered roller bearing design that helps reduce hub-face deflection under load. This improves steering precision, braking stability, and alignment consistency while supporting the demands of modern half-ton trucks running larger wheel and tire combinations.

Built for harsh real-world conditions, the KR6491 features Grade 10.9 cold-formed zinc-plated wheel studs for exceptional tensile strength and corrosion resistance. A heavy-duty integrated ABS sensor is engineered to maintain accurate signal performance in heat, mud, moisture, and salted-road environments.

Every hub assembly is protected with a complete E-coating for outstanding resistance against rust and corrosion, while maintenance-free operation is achieved through high-performance grease and durable tapered roller bearing construction.

Whether your Silverado is used for daily driving, towing, work duty, or off-road adventures, Kryptonite wheel bearings are built to deliver the strength, precision, and reliability serious truck owners demand.

Backed by the Kryptonite No Fine Print Lifetime Warranty, these wheel bearings are covered against manufacturer defects, premature wear, and breakage.
