Upgrade your vehicle’s 4-wheel drive system with our heavy-duty locking hubs, designed to provide enhanced performance and reliability. Manually locking your vehicle into 4-wheel drive has never been easier or more durable.

Constructed from stainless steel, these locking hubs ensure a secure engagement that withstands the toughest driving conditions. The kit includes springs, clips, and a wrench for straightforward installation, making it a convenient DIY project. Compatible with 30 spline axles, this pair of hubs is designed to fit a range of vehicles – be sure to check our fitment guide for specific compatibility.

Who Is This For?

These locking hubs are ideal for off-road enthusiasts and individuals who require a reliable 4-wheel drive system for heavy-duty applications. If you’re currently using automatic hubs and looking to upgrade to a more robust manual system, this product is a great choice. Note that if you’re converting from automatic hubs, you may need to purchase a nut kit separately.

Bottom Line

With a limited lifetime warranty, our locking hubs offer a durable and cost-effective solution for enhancing your vehicle’s 4-wheel drive capabilities. By manually controlling your vehicle’s drive mode, you’ll enjoy improved traction and control on challenging terrain.

I recently had the opportunity to install the Mile Marker Premium Locking Hubs (449SS) on my Jeep Wrangler, and I must say, I am thoroughly impressed with this product. The installation process was straightforward, thanks to the inclusion of springs, clips, and a wrench in the package.

What stood out to me was the heavy-duty stainless steel construction. This locking hub feels robust and well-built, giving me confidence that it will stay engaged during my off-road adventures. The manual lock for switching between 4-wheel drive and 2-wheel drive works smoothly, making it easy to switch as needed.

One important note is that these hubs are designed for 30 spline axles, so be sure to check the fitment guide before purchasing. Additionally, if you’re converting from automatic hubs, a nut kit may be required. However, Mile Marker provides clear instructions to help with this process.

I appreciate the fact that these locking hubs come as a pair, saving me the trouble of buying two separate units. The limited lifetime warranty is an added bonus, ensuring that I can rely on these hubs for years to come. Overall, I’m very satisfied with my purchase and would recommend the Mile Marker Premium Locking Hubs (449SS) to anyone looking to upgrade their 4×4 vehicle.
