Synergy Jeep Wrangler TJ/TJL/YJ/XJ/ZJ HD Non-Knurled Front Ball Joint Set Dana 30/44

Our 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. After over 5 years of development and over 500,000 test miles of research and development and serious abuse, these ball joints are the highest quality ball joints on the market. Our 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 offroad riding.
