Ball joints are a common wear item on Jeep wranglers that can produce vibrations, steering wander or even clunking noises. When installing a lift kit on your Jeep Wrangler JK it’s a great time to replace the weak factory ball joints with a heavy-duty joint that is designed to handle additional stresses of oversize tires. Rough Country’s replacement ball joints are designed from the ground up to give you a stronger, longer lasting ball joint that is a direct factory replacement.
