Synergy Manufacturing Dana 30/44 Ball Joint Set - LJ/TJ/XJ/YJ/ZJ
 
Synergy Jeep TJ / LJ / ZJ / XJ / MJ / YJ Heavy Duty Ball Joint Kits replace your Jeep's factory ball joints with heavy duty ball joints. These ball joints are the highest quality ball joints on the market. The fully greaseable metal on metal design improves durability and performance. The extra large ball joint bearing surface eliminates the inner nylon liner, creating a longer lasting, more reliable joint. If you have a lifted jeep, then you need heavy duty ball joints to put up to the abuse of bigger tires and off-road driving. NRT Autosports has thousands of off-road race miles with zero failures using these joints
