High-Quality Performance Ball Joint Kit Have you noticed your vehicle wandering on the road, a decreased steering feel, extra wobble, or tire-tread cupping and feathering? If so, it's time to upgrade to the Dynatrac ProSteer Ball Joint Kit as it features 4 balljoints, 4 nuts, 4 cotter pins, and 2 safety snap rings. With larger tires, factory balljoints can develop excessive play and movement in as little as 20,00 miles. In order to prevent this from happening, Dynatrac's ProSteer Ball Joint Kit will provide improved steering, strength, and control to your vehicle thanks to the hardcore construction of these ball joints. While the factory balljoints use a nylon insert to house the ball socket in the opening, Dynatrac's balljoints use a heat-treated, precision-ground stainless steel ball in a heat-treated, high-strength billet body. This reduces wear to the unit over time to provide impressive durability even during the most extreme applications. Premium Construction & Installation Info Your OEM balljoints often wear quickly with larger off-road tires, so Dynatrac designed their ProSteer Balljoints using high-strength billet bodies and chromoly stems for maximum strength and long-lasting durability. Moreover, these ball joints are completely rebuildable without requiring the balljoint body to be removed from the axle housing. Unique seals prevent contamination, and the balljoints have greaseable fittings and Teflon-coated wear points to provide a long, durable life. Installation is made simple an straightforward as these were designed as a direct replacement of your factory components.
