Synergy Mfg heavy duty ball joints are designed to replace the factory ball joints that are prone to premature wear on lifted vehicles with large off-road tires.

Review: Work so far - Got my local shop to install these based on their recommendation.... very satisfied so far, only been off roading once. Little stuff after install, but I’m about 800 miles in now and very happy with the break in period and piece of mind.
Review: Good quality ball joints - I have used Synergy ball joints on 3 different axle builds. No issues with them and with regular grease maintenance they have lasted years.
