ICON: Front Tubular Upper Control Arms W/ Delta Joint Pro – 2024-25 Toyota Tacoma/2024-25 Toyota Land Cruiser 250 Series/2024-25 Lexus GX550/2025 Toyota 4Runner

Description

These tubular steel upper control arms free up your 2024-2025 Toyota Tacoma, 2024-2025 Toyota Land Cruiser 250 Series, 2025 Toyota 4Runner, or 2024-2025 Lexus GX550’s front suspension movement to allow maximum travel for performance coilovers at an easier price point compared to our range-topping billet components. Additional caster is built in to correct geometry to allow for better front-end alignment on lifted vehicles. The all-new Delta Joint PRO provides a host of durability and performance improvements compared to our standard Delta Joints, including up to 90° of free articulation to maximize suspension travel without bind. It’s also larger and fully rebuildable. The Delta Joint PRO’s grease fitting is protected by an anodized billet aluminum dust cap, included with the kit. Serviceable Heavy Duty Dual Stage bushings at the frame pivots are greaseable and rebuildable, and fit into precision machined bushing housings to ensure a responsive driving experience. ICON Tubular Upper Control Arms are constructed of heavy wall DOM tubing, CNC formed and fixture welded before receiving our multi-stage semi-gloss black powder coat finish. Includes all components and hardware necessary for a complete install, these tubular UCAs are the perfect front end upgrade for the Toyota Tacoma, Land Cruiser 250 Series, 4Runner, and the Lexus GX550.

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.
