This front hub assembly drops in as a direct-fit replacement for the 2018-2025 Chevrolet Express 2500 and Express 3500, the 2018-2025 GMC Savana 2500 and Savana 3500, and the 2021 GMC Savana 4500 — see the "Vehicles it fits" section for the full engine-level fitment. Engineered in-house with application-specific upgrades, it's built for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks.
- Pre-filled with premium grease: the lubricant withstands high temperature and extreme pressure, resists corrosion and reduces friction.
- Multi-point sealing system: layered defense helps keep contaminants out and vital grease in.
- Precise ABS signal quality: increased gauge and strain reliefs give the ABS cable abrasion resistance and added cable strength.
- Labor Saver design and hardware: intended to make installation faster and easier.
High-grade materials are used across the components for longer part life, and each assembly is backed by extensive in-house and third-party durability testing. As a front wheel bearing and hub assembly, it supports the wheel, lets it rotate smoothly on its bearing, and integrates the ABS wheel-speed sensor. If a worn or damaged front hub is the source of your bearing noise, this replaces it.
