ICON Vehicle Dynamics 78720DJ Billet Upper Control Arm Kit with Delta Joint for 2019-2024 GM 1500

The ICON Vehicle Dynamics 78720DJ billet aluminum upper control arm kit delivers enhanced performance and proper front-end geometry for 2019-2024 GM Silverado/Sierra 1500 pickups and 2021-2024 GM SUVs. Engineered to correct suspension geometry on lifted or leveled vehicles, these precision control arms provide adjustable camber and caster settings while eliminating the suspension bind common with stock components.

Key Features:

• CNC Machined 6061 Billet Aluminum Construction: Combines exceptional strength with lightweight design for optimal performance and durability
• Patented ICON Delta Joint Technology: Replaces OE ball joint with a revolutionary high-angle joint (U.S. Patent No. 10,731,700) that delivers uniball-like articulation with superior weather sealing and longevity
• Full Adjustability: Double adjuster sleeve design allows precise on-vehicle camber and caster adjustment for perfect wheel alignment
• PTFE Lined 7/8" FK Rod Ends: Premium Heim joints provide smooth, precise operation throughout the full range of suspension travel
• Vehicle-Specific Taper Pin: Ensures OE-quality fitment and installation
• Complete Kit: Includes all necessary components and hardware for installation

Delta Joint Innovation:

The ICON Delta Joint represents a breakthrough in upper control arm technology, bridging the gap between traditional ball joints and uniballs. This heavy-duty component features a zinc-plated housing for corrosion resistance, robust grease seals to protect against the elements, and a greaseable metal-on-metal design for quiet, long-lasting operation. Unlike exposed uniballs that can deteriorate in daily driving conditions, the Delta Joint delivers superior angularity with the durability and weather protection needed for street-driven vehicles.

These billet upper control arms are the ideal upgrade for GM 1500 owners running lifted or leveled suspensions, restoring proper suspension geometry while allowing full bump and droop travel without binding.
