DICMIC 2Pcs 4WD Auto Locking Hub for Ford F-250/F-350/F-450/F-550, Expedition, Excursion, Navigator | 600-203 & 1C3Z-3B396-CB

Upgrade your 4WD with DICMIC locking hubs

Designed for select Ford trucks and SUVs, these locking hubs offer a smart way to disengage the front-wheel connections when 4WD isn't needed. When four-wheel drive is engaged, torque is transmitted to the front axle; when disengaged, the hubs release to reduce drivetrain load, potentially improving efficiency and ride comfort.

These hubs replace part numbers 600-203 and 1C3Z-3B396-CB and are built to fit a range of Ford trucks and SUVs from late 1990s to early 2000s. The assembly is designed for straightforward replacement, with or without removing the wheel, depending on your truck’s configuration.

Key Benefits and Real-World Use

• On-the-fly disengagement: The hub auto-aligns in 4WD and slides out when switching to 2WD, supporting efficient highway cruising.
• Front drivetrain protection: Reducing unnecessary front-axle load can help minimize wear on the differential and related components over time.
• Fuel-efficiency potential: Less drag from the front axle when wheels rotate freely in 2WD, especially on long highway trips.
• Vehicle compatibility: Fits Ford F-250, F-350, F-450, F-550 (1999–2004); Expedition (2001–2002); Excursion (2000–2005); Navigator (2001–2002).

What to Expect During Replacement

• Part numbers to verify: 600-203 and 1C3Z-3B396-CB ensure correct replacement.
• Simple steps you’ll follow: remove the hubcap if present, lift out the retaining ring, pull the lockout hub, and install the new hub in reverse order.
• Practical tips: verify year/make/model before purchase; have a pry tool handy for hubcap removal if needed.

Note: Please confirm the Year/Make/Model compatibility before purchasing. If you have questions, we respond promptly to help ensure you choose the right hub.
