Carli Ball Joints for 2003-2012 Ram 2500/3500 radius-arm trucks are engineered to be the last set of ball joints you’ll ever need, offering a lifetime solution far superior to the OEM design. While factory Ram HD ball joints use a simple lower joint and an upper floating king-pin with a coated sleeve—creating a single wear surface and a common point of failure—Carli completely re-engineered the concept for strength, longevity, and serviceability.

Carli’s design retains the floating king-pin style but adds major improvements:

• Dual wear surfaces by allowing the pin “hat” to contact the housing, distributing lateral loads more effectively.

• No internal sleeve, eliminating a critical OEM failure point.

• Increased upper cavity volume for significantly more grease capacity.

• Threaded service cap with zerk fitting for easy maintenance and long-term lubrication.

• Precision-machined grease channel in the pin for proper lubrication flow.

• Viton environmental seal at the base for maximum contamination resistance.

Built from premium materials and refined through extensive destructive testing, Carli Ball Joints deliver unmatched durability, smoother steering feel, tighter tolerances, and true lifetime performance for Ram HD owners.
