This special package from Carli Suspension saves you $100 when compared to buying the uppers and lowers seperately!
Extensive testing on the ball joints through Carli Suspension's product research and development cycle is now complete. We have logged thousands of nasty dirt miles over the past year to ensure that this product would be everything you have come to expect from us. These new Extreme Duty Ball Joints should yield a service life for as long as you own your truck and we're confident enough to offer a lifetime warranty. With an average labor of $500.00, the end user actually saves money the first time that they don't have to replace them.
The ball joints start out as a chunk of 4130 chro-moly which is machined to our unique two tiered, internal grease port, patent pending design. The ball joint is then heat treated to a specified rockwell (hardness) that we have tested and set to make them able to withstand the meanest of beatings without showing any fatigue. From there the ball joints head to an aero-space lube company where a proprietary dry-lube is applied to our specified thickness. And of course we top them off with an accessible zerk fitting for easy servicing plus we even include a tube of high quality synthetic grease with each pair.
The ball joints are designed to break in after use. Constructed out of 4130, hardened and machined again makes for a smooth surface. With any hard smooth surface, there will be pores or high spots, not visible by the eye, but under extreme magnification you will be able to detect contact points raised from the general surface plain. The 2-stage aerospace dry lubrication process fills the pores of the machined surface and after significant period of time and consistant use, the surface will burnish. The definition of Burnish means to polish by friction. This is built into the design of the assembly and accounted for in the hard dry lubricant process. After removing the pin from the assembly following our testing periods, the surface has a luster to it which is the affect of the burnishing through normal use of the product. The burnished surfaces will reduce friction and smooth out rotation even further.
Without diving into a lesson on metallurgy, what we have discovered is that the ball joints get even better over time. Still flowing Redline CV2 high performance grease combined with the 2-stage machine applied dry lubricant process, the sheer pressure of the activity that the upper ball joint is subject to allows for the burnishing process to take place and when reviewed, you can see by eye and feel by touch that the surface is smoother. Just the way it was designed to do.
Starting out from billet 4130 stock and CNC machined into a two-piece assembly, then case hardened, this truly is a bullet-proof component. The best part is the ride quality improvement over O.E.M. ball joints. The ball and socket on factory Dodge Ram Upper Ball Joints is separated by a plastic break-away that under severe stress, deflects.
By removing even .0625 inches of deflection times two axle ends omits 1/6" of an inch, or more, of ball joint deflection. You can feel it in the steering wheel. 35 and 37 inch tires, more stress and off-road impacts only exaggerate the movement, and subsequently, its affect. Your truck feels tighter and the steering wheel goes numb, even over pot holes and rail road tracks. The secondary tire movement, once eliminated, gives you a more controlled feel. Sometimes when you hit a sharp lip on the street, it feels like you hit two bumps, that aftershock is the tire's secondary movement from O.E.M. lower ball joint deflection. The front end of your truck will feel improved, or we'll buy the product back from you - guaranteed.
