Description

If you own a Ram HD and you’ve spent any time researching front end parts, it’s likely you’ve heard of Carli Ball Joints. Well, now those in possession of a post-2013 suspension redesigned Ram HD equipped with factory radius arms have the ability to install their last set of ball joints. Now that the research has begun and our customers are overloaded with information, what’s the benefit to these Carli Joints?

The main differentiators that matter – materials, process, and design. Our philosophy has always been to skip on the enumeration of materials and process. Leave this to the engineers way smarter than those of us within the organization who are put to the task of trying to destroy the products they design. As our lifetime ball joints have been in circulation for many years and more competition enters the market, the “what makes these so special” questions surfaces regularly; we’re happy to shed some light!

The design comes first. To know how we improved it, let’s take a look at the factory. The Factory Ball Joints are made up of a lower ball joint and upper floating king-pin. What better way to learn a product than to cut it in half to learn it’s functionality.

The lower ball joints are the true ball joints in the AAM design. The spherical lower is a ball and socket design allowing lateral misalignment (unlike the king-pin upper). Because the design tracks the knuckle on an imperfect axis, the spherical lower is required to allow the knuckle to move freely with only a slight vertical travel through its steering cycle. By design, the lower factory joint is a pin isolated from the housing by a nylon material loaded from the top and sealed by a press with a boot to keep out the elements. When this composite liner fails, the ball joint needs to be replaced. It’s the old saying, a chain is only as strong as its weakest link.
Lower Ball Joint Comparison

Our improvement on this design begins with the ability to service the joint. The Zerk fitting is recessed into the top of the joint and protrudes at an angle to be aimed forward and slightly inward to allow access to the fitting without needing to disassemble anything. In the cutaway, you can see the channels machined into our ball surface conducive to grease migration. Again, you’ll see no liners of any kind. At the top, a bronze wear surface preloaded by a disc spring, safety washer and snap ring ensures the ball joints wear surfaces are always held tightly together for optimal performance. Not shown in the picture but including in our lower is a rubber seal locking the housing to the pin.

Now that the design improvements are clear, why are we so confident in the materials that we think we can eliminate wear-surface isolation? We have tested every possible material and process to land where we have since the inception of these lifetime ball joints in 2007. Our process starts with masking. We mask the ball joints, all but the wear surface with a copper plating. Once plated, the ball joints head to carburizing. The carburizing creates an extremely hard surface with a case-hardness (penetrating depth) of 20-25 thousandths. For reference, another process we tried was salt-bath nitride which produced 3 thousandths in a best-case scenario. When the ball joint has completed the carburizing/heat treat, they’re stripped of their copper masking leaving the entire joint heat treated and the wear surfaces incredibly hard. From stripping, they head to dry-lube where the whole joint is coated with a corrosion resistant gray coating to project the joint while the lubricity of the coating pairs with ant seize and Redline CV2 grease to assist in breaking in the wear surfaces.

Normally, this is where you list the recipe of materials – well, we don’t want to spell out everything for the competition.  The time we’ve put in (literal blood, sweat, tears) and hundreds of thousands of dollars to develop this indestructible product have led us to safeguard this recipe with our life. What we will do, back these ball joints with the industry’s only ADVANCED REPLACEMENT Lifetime Guarantee (Only applies when both Carli Upper and Lower Ball Joints are installed). Keep your purchase receipt and know you’re set for the life of the truck. If anything should happen, shoot us a video of the play (Excess of .040” vertical or .020” lateral) and your purchase receipt and we’ll have replacements enroute with a call tag to return the defective joints; simple as that. When you receive the new ones, swap them in and send the old ones back with the included call tag. It’s more expensive for us to do it this way and we end up replacing a lot of joints that either haven’t failed or were damaged by the installer but it’s a small price to pay to provide the best product and peace of mind that we’ll have our customer’s back regardless.
