TeraFlex 3440000 JK Dana 30/44 Heavy-Duty Adjustable Ball Joint Kit Pair

Upgrade the front axle of your 2007–2018 Jeep Wrangler JK with the TeraFlex 3440000 Heavy-Duty Ball Joint Kit. Designed for Dana 30 and Dana 44 applications, this complete pair provides replacement upper and lower ball joints for improved durability and dependable suspension operation. The kit is intended for press-in installation and offers a practical solution for worn or damaged factory ball joints.
The TeraFlex 3440000 ball joints feature an adjustable design that helps accommodate wear and maintain proper fit over time. This adjustability supports more precise front-end service and can help restore the controlled steering response expected from a properly maintained suspension system. The heavy-duty construction is well suited for Jeep owners who use their Wrangler for daily driving, trail use, or upgraded suspension and tire applications.
Each ball joint is greaseable, allowing routine lubrication to support smooth operation and help extend service life. Greaseable fittings make ongoing maintenance more convenient while helping protect the joint from premature wear caused by dirt, moisture, and demanding driving conditions. As a matched pair, the kit provides coordinated upper and lower ball joint replacement for the applicable axle assembly.
The TeraFlex 3440000 kit is designed specifically for Jeep Wrangler JK models from 2007 through 2018 equipped with Dana 30 or Dana 44 front axles. Verify the axle configuration and vehicle application before installation. Professional installation is recommended, as press-in ball joints require suitable tools and correct procedures for removal, installation, adjustment, and final suspension inspection. After installation, inspect steering and suspension components and complete any required alignment checks.
