The ICON 58552DJ Billet UCA Delta Joint PRO is a high-performance suspension articulation joint designed for off-road applications. It combines the durability and longevity of factory-style ball joints with enhanced performance and strength that surpass traditional motorsports-style joints. Featuring a rebuildable and serviceable design, any component can be removed, inspected, and replaced independently, reducing the need for complete replacements. The Delta Joint PRO utilizes a larger ball with 56% more bearing surface than standard versions, along with improved lubrication sealing for increased durability. Constructed with a chromoly ball and shaft hardened to Rockwell C 55, it offers a full 90 degrees of articulation—14% more than previous models—allowing maximum bind-free suspension movement through the entire range of travel. The design incorporates machined, graphite-impregnated sintered metal races for a flawless metal-to-metal interface and an optimized lubrication system for efficient grease distribution.
This product is engineered as a direct replacement for 2024–2027 Toyota 4Runner, Tacoma, Lexus LC250, and GX550 models. It is compatible with vehicles equipped with factory or aftermarket suspension systems that require a high-strength, rebuildable upper control arm with enhanced articulation. The ICON Delta Joint PRO is ideal for off-road enthusiasts seeking increased suspension flexibility, durability, and performance in demanding terrains. Installation involves replacing the existing upper control arm with this bolt-on component, providing a reliable upgrade for off-road, trail, and overlanding use. The kit includes the billet UCA and Delta Joint PRO, designed to withstand harsh off-road conditions and extended use.
