Tubular Upper Control Arm Delta Joint Kit | 2021+ Bronco

These tubular steel upper control arms free up your 2021-2023 Ford Bronco's front suspension movement to allow maximum travel for performance shocks and 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 Broncos. 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 black powder coat finish. 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.
