Improved Off-Road Performance Your Jeep's weak factory ball joints aren't made for constant off-road abuse, so it only makes sense to upgrade to a high-quality replacement that can handle all of your extreme applications. Teraflex's Heavy Duty Replacement Ball Joints are a unique and effective solution to handle the demands of your off-road style. Engineered to perform under heavy stress with excellent wear, these ball joints will set your Jeep apart from the rest by outperforming your factory ball joints. Better yet, this kit includes grease zerks for easy maintenance of the ball joints, so you can get back to what's really important in no time. Heavy-Duty Construction The Teraflex Heavy Duty Ball Joints are made from a 4140 chromoly steel for extreme strength and long-lasting functionality. Additionally, the ball joints are heat treated in order provide incredible fatigue and abrasion resistance, ultimately increasing the lifespan of these units. These ball joints also feature metal bearings to handle rotational load and a threaded cup, carbon steel spring plate for superior performance under your Jeep's weight.
