      Description

      Heavy-Duty Control. The Synergy Manufacturing HD Knurled Ball Joint Set is engineered to restore precise steering and suspension articulation while significantly improving durability over factory components. Designed for demanding driving conditions, this set plays a critical role in maintaining proper wheel alignment, steering response, and front-end stability.

      Construction and Appearance. Built with a fully greaseable metal-on-metal design, these ball joints are manufactured for exceptional strength, longevity, and consistent performance under load. The knurled housing design enhances press-fit retention in the knuckle, reducing the risk of movement over time. Precision machining and high-quality materials ensure smooth articulation while resisting deformation, making them well suited for vehicles exposed to larger tires, suspension upgrades, and frequent off-road use. Made in the USA, the construction reflects a focus on strength, reliability, and performance-driven engineering.

      Installation. Designed as a direct replacement, installation follows standard suspension service procedures using appropriate pressing tools. The set includes both upper and lower ball joints to support a complete front-end refresh. Proper greasing during installation and routine maintenance afterward helps ensure smooth operation and extended service life. Professional installation and a post-installation alignment are recommended to achieve optimal handling and steering performance.

      Application. This Synergy Manufacturing HD Knurled Ball Joint Set fits 1987-2006 Jeep Wrangler TJ and YJ models. By replacing worn factory ball joints with heavy-duty, greaseable components, it enhances steering precision, improves suspension reliability, and supports confident handling both on and off the road.
