Dynatrac's Dyna Loc Locking Hubs

The DynaLoc hubs have been proven to be more than three times stronger than conventional hubs. Should they ever break, they default into a locked position. They are produced using tempered heat-treated chrome-moly steel. The low-profile steel bezel and aircraft-quality aluminum knob give a much more subtle look and do not stick out nearly as far as other locking-hub faces.

The time has come for stronger hubs. Our trucks need the increased strength to meet the demands of stouter drivetrains and higher-torque applications in today's off-road world. No longer are standard locking hubs holding up to the mega-horsepower engines and monster truck tires. We've just simply built our trucks to beyond the capacity that typical locking hubs were ever meant for.

And if you're not one of those guys who enjoys fixing things, then you might want to look into a set of Dynatrac's DynaLoc locking hubs. Through stress testing, the DynaLocs have been proven to be more than three times stronger than other standard locking hubs, and should they ever fail (there has not been one reported case yet), they'll default into a "locked" position instead of an "unlocked" position. But with the DynaLocs costing more than twice as much as other locking hubs, you'll have to decide for yourself whether it's worth it or not. But remember that if you're breaking hubs, then there's a good chance you've already spent more money on replacements than you would on one pair of DynaLocs.

Dynatracs Dynaloc Locking Hubs Dynalocs Are Dynamite Super Duty Tire

We threw our set onto our big Super Duty, and though we haven't really bound-up the truck in some severe rockcrawling, we are never really kind to anything we use or test. And with 40-inch tires, a high-torque diesel engine, and a heavy curb weight, we can only imagine the stress we've been putting on these hubs. Due to their design, the inner and outer locks actually pull together when under stress, instead of trying to push apart. This only adds to their strength and durability.

One thing we have noticed is that the DynaLoc locking hubs are sometimes a bit tougher to get unlocked than typical hubs. If yours are bound up, and you can't turn the knob, then simply crank the steering wheel back and forth a couple times (while the truck is in 2WD), and you should be able to free them up.

If you have locking hubs, then we're guessing you know the breakdown-and-replace routine with hubs. Take this opportunity to look at your wheel bearings and make sure there is no dirt or water inside your hub and that the bearings do not need to be repacked or replaced.The DynaLocs have a different design than a standard locking hub, but Dynatrac's included directions are very good, and you should have no problem attempting this yourself.Once we had the original locking hubs stripped off our truck, we started our install.

The first things to slide in are a spacer ring and a baseplate. Once the spacer and plate are sitting against the wheel bearing, you can place the wave spring and outer lock. It is good to get some grease on those teeth. Push down on the outer lock once you have it and the wave spring butted up against the plate. The outer lock should slide freely.

Now you'll have to place the crown cam in the hub. When the DynaLoc's knob is turned to the "unlocked" position, it pushes down on the crown cam. The crown hub is a larger diameter than the inner lock, so when pressure is placed on the crown cam, it goes right over the inner lock and pushes down on the outer lock. Subsequently, the outer lock is pushed away from the inner lock, releasing it from the axleshaft. So when you unlock the hub, you are actually putting pressure against the wave spring. And this is how the hub has a default "locked" design, should it ever break and release.

The lock knob has an O-ring that sits between the knob and the bezel. Make sure to apply grease to it. The DynaLoc hubs are extremely simple to install, except for this last step: When you put the knob in the bezel, it is imperative to have the "X" (locked position) on the bezel lining up right next to the "c" at the end of the Dynatrac logo on the hub. In this image, we have not yet rotated the knob to the correct position, and if we were to try to install it this way (backward), then the hub would not work properly.
