Why do hubs fail?

On the conventional locked system, OEM hubs fail due to the added rotation and deflection load produced by steering. When driving in 4WD, front axle components are constantly engaged wearing down your front steering components, front drivetrain and transfer case. Hub failure is the result of the absence of proper maintenance. When neglected, all hubs fail, this is why LHC hubs created a locking hub conversion kit that can be easily serviced with our special greasing tool.

Why Upgrade From OEM Full Lock 4WD hubs?

Saving money is the primary reason LHC created conversion kits based on the unit bearing system. LHC conversion kits cost less to install (Net Installation Cost) and are cheaper to maintain over time (Total Cost of Ownership).

When comparing conversion kits it is necessary to include the cost of labor to the product cost to see the Net Installation Cost of upgrading your OEM unit bearing hubs. LHC conversion kits have the lowest Net Installation Cost of any hub conversion kit in the industry. Likewise, LHC manual locking hubs have the lowest Total Cost of Ownership, as unit bearing hubs do not require complete disassembly when performing regular maintenance.

What vehicles are supported?

LOCKING HUBS CO. - LHC supports all Dodge ½ ton, ¾ ton and full ton trucks (2500, 3500, 4500, 5500) from 1996 to 2016.

How far do your hubs stick out?

LHC manual locking hubs do not stick out from your wheel in any way. In fact, LHC is the only manufacturer that offers a true low-profile solution. Our manual locking hubs can fit under your original hubcaps.

Why do other websites say that OEM unit bearings are “vulnerable” or “prone to breaking”?

Competing manual locking hub manufacturers claim that unit bearing hubs are “problematic” or “vulnerable” to deceptively justify the use of out-dated, obsolete hub technology. Currently, all modern vehicles are manufactured using the unit bearing hub system due to its superior design. Vehicle manufacturers abandoned the spindle bearing hub design over 25 years ago, due to the high cost of repair, the difficulty of installation, and the disruption of ABS braking systems.

Why do your hubs have less parts?

LHC manual locking hubs are based on the unit bearing hub system. By design, our manual locking hubs only have 3 components, the stub shaft, the unit bearing hub and the locking mechanism itself.

By rejecting the spindle bearing hub design, LHC eliminated the need for the irreparable custom parts, and the labor-intensive installation and maintenance. Where the spindle bearing hub design requires a complete rebuild, and over 7hrs to install, unit-bearing hubs can be installed and maintained a couple of hours.

Not only is the spindle bearing hub design dependent on a number of custom parts, but also each part is proprietary, and nearly impossible to source from manufacturer.

How easy is installation and maintenance?

LOCKING HUBS CO. - LHC locking hub conversion kits are the fastest to install and the easiest to maintain. The entire process requires less time and can be completed in a couple of hours. By comparison, spindle bearing hubs are labor intensive, take 5-10 hours to install and the use of specialized tools and equipment.

Likewise, hub maintenance is simple and quick with our manual locking hubs. As with all unit bearing hubs, LHC hubs are serviceable through the ABS port. In relationship to spindle bearing hubs, our manual locking hubs can be serviced quickly and don’t require a full tear down and rebuild.
