Product Description

The Carli CS-DUBJ is a set of Extreme Duty Upper Ball Joints machined from case-hardened 4130 chromoly steel and built to outlast the factory joints on 2003-2025 RAM 2500/3500 4WD trucks. A patent-pending two-tiered internal grease port and two-stage dry-lube process cut friction and extend service life, while the copper-plated, carburized finish resists corrosion and wear under heavy load and off-road abuse.

Each joint includes an accessible zerk fitting for routine servicing and ships with a tube of Redline CV2 synthetic grease to get started. Built and finished in the USA, these are designed for Ram HD owners who tow, haul, or wheel hard and want a genuine, install-once upgrade - pair them with Carli's matching lower ball joints to qualify for the brand's lifetime Advanced Replacement Guarantee.
