ICON suspension components with the all-new Delta Joint PRO represent the state of the art in off-road performance and durability. Delta Joint PRO is ICON's innovative new suspension articulation joint which combines the durability and longevity of factory style ball joints with performance and strength that exceeds traditional motorsports-style ball joints. The Delta Joint PRO features a new rebuildable, serviceable design in which any component may be removed, inspected, and replaced without having to purchase a whole new joint. Strength and durability are improved by using a larger ball with 56% more bearing surface than our standard Delta Joint, along with improved lubrication sealing. But improved performance is at the heart of the Delta Joint PRO, with a full 90 degrees of articulation, from one extreme to the other. This represents a 14% improvement in range of motion, over the highly capable original Delta Joint, allowing for maximum bind-free suspension movement through the complete range of travel. The Delta Joint PRO is built to take the abuse, with a chromoly ball and shaft that has a bearing surface hardened to Rockwell C 55. The replaceable races are made of graphite-impregnated sintered metal, machined to the finest tolerance to provide a flawless, metal-to-metal bearing interface. We also redesigned the lubrication system, with lubricant channels that distribute grease more efficiently without extending past the bearing seal. ICON tubular upper control arms feature 1026 DOM tube construction, polyurethane bushings, and ICON*s Delta Joint Pro, a rebuildable high-angle ball joint with the the durability of a ball joint and the performance of a traditional uniball.
