ICON Vehicle Dynamics Delta Joint 1-Inch Retrofit Kit for GM and Ford UCAs

The ICON Vehicle Dynamics Delta Joint 1-Inch Retrofit Kit (SKU 614555) replaces the upper control arm joint on compatible GM large-taper and Ford platforms, combining the durability of a ball joint with the angularity of a uniball in a single greaseable, sealed unit. It is designed for use exclusively with ICON upper control arm kits on lifted applications and is not a universal fitment part.

Greater Angularity Without Sacrificing Durability

The Delta Joint's patented design (U.S. Pat. 10,731,700) achieves the high steering angularity that lifted trucks require while retaining metal-on-metal internals that outlast conventional uniballs in harsh conditions. For a truck running significant lift, that combination means the front suspension can move through its full range of travel without binding, a limitation that forces compromises in alignment and handling on many aftermarket UCA setups.

Sealed and Greaseable for Long Service Life

A zinc-plated housing and sealed construction keep road salt, mud, and debris away from the joint internals. The greaseable design lets owners service the joint on a regular maintenance interval rather than replacing it when wear becomes audible. That serviceability represents a meaningful cost and downtime difference over the life of a build. Metal-on-metal contact also eliminates the creaking and popping that polyurethane or worn rubber joints produce under articulation.

Application-Specific Taper Pins Reduce Installation Risk

Each kit includes a carburized taper pin matched to the specific vehicle application rather than a generic tapered stub. Carburizing increases surface hardness, which reduces internal friction and lowers the chance of thread galling when the pin is torqued during assembly. Thread galling is a common failure point with generic hardware on high-load suspension joints.

Features

• Patented Delta Joint (U.S. Pat. 10,731,700): combines ball-joint durability with uniball-level angularity
• Sealed, zinc-plated housing: resists road salt, moisture, and debris
• Greaseable metal-on-metal internals: serviceable design for long life and noise-free operation
• Carburized taper pin: reduced friction, corrosion resistance, and lower thread-galling risk on assembly
• Application-specific taper pins: precise fit across a defined range of GM and Ford vehicles
• Pullout strength: exceeds comparable industry-standard uniballs

Specifications

Who This Is For and Isn't

This kit suits owners of compatible GM large-taper or Ford platform trucks running ICON upper control arms (or planning to install them) on a lifted application, who want a joint that handles high angularity demands without sacrificing serviceability or long-term durability.

This kit does not fit the F-150 Tremor, F-150 Raptor, or Chevrolet Colorado ZR2. It is a retrofit component for use with ICON UCA kits and is not designed as a standalone or universal ball joint replacement.

Common Questions

Does this Delta Joint kit work with any upper control arm, or only ICON UCAs?

The ICON Delta Joint 1-Inch Retrofit Kit is designed for use with ICON Vehicle Dynamics upper control arm kits. The application-specific taper pins are matched to ICON UCA geometry, and the 5-year limited warranty applies only when the joint is used with ICON suspension components.

Will this kit fit a Ford F-150 Raptor or Tremor?

No. The ICON Delta Joint 1-Inch Retrofit Kit does not fit the F-150 Raptor or F-150 Tremor. Buyers with those vehicles should confirm compatibility with a fitment-specific ICON kit before ordering.

Does it fit the Chevrolet Colorado ZR2?

No. The ICON Delta Joint 1-Inch Retrofit Kit is not compatible with the Chevrolet Colorado ZR2. Buyers with a Colorado ZR2 should consult ICON's fitment guide for the correct kit.

What makes the Delta Joint more durable than a standard uniball?

The ICON Delta Joint uses metal-on-metal internals, a sealed and zinc-plated housing, and a carburized taper pin. Those features resist corrosion, reduce internal friction, and deliver pullout strength greater than comparable industry-standard uniballs.
