ICON Vehicle Dynamics Delta Joint Retrofit Kit for Toyota 4Runner, FJ Cruiser and Land Cruiser 200

The ICON Vehicle Dynamics Delta Joint Retrofit Kit replaces the uniball in ICON front upper control arms on 2003–2024 Toyota 4Runner, 2007–2014 Toyota FJ Cruiser, and 2008–2021 Land Cruiser 200 Series vehicles, delivering the corrosion resistance of a sealed ball joint alongside the high-angularity articulation a lifted daily driver demands.

Sealed Where Uniballs Are Not

A conventional uniball allows low-bind articulation but leaves metal-on-metal surfaces open to water, road salt, and debris, which is a real liability on a vehicle driven year-round. The Delta Joint addresses this with a zinc-plated housing as the outer corrosion barrier and a tough grease seal that keeps contaminants away from the joint's internals. For an overlanding rig or lifted daily driver that sees wet trails and winter roads, that sealed construction means the joint stays functional and quiet far longer than an exposed uniball.

High Angularity Without Sacrificing Strength

Lifted applications push a front upper control arm through angles that exceed what a standard ball joint can handle cleanly. The Delta Joint's patented geometry (U.S. Pat. 10,731,700) achieves the high articulation range a lifted suspension requires while maintaining pullout strength that exceeds a comparable industry-standard uniball. A carburized taper pin reduces internal friction, resists corrosion at the pin itself, and limits thread galling during assembly. These details matter when the joint eventually needs service in the field.

Greaseable and Built to Last

Metal-on-metal internal construction combined with a greaseable design lets the Delta Joint be serviced rather than replaced at the first sign of wear. Application-specific taper pins ensure a precise fit across the 4Runner, FJ Cruiser, and Land Cruiser 200 Series platforms rather than relying on a generic adapter. The result is noise-free operation and a joint that can be maintained on a regular service interval rather than treated as a consumable.

Features

• Patented design (U.S. Pat. 10,731,700): combines ball-joint durability with uniball-style articulation range
• Zinc-plated housing and grease seal: dual-layer protection against road salt, water, and debris
• Carburized taper pin: reduced internal friction, increased corrosion resistance, and less thread galling on assembly
• Greaseable, metal-on-metal internals: serviceable design for long-term noise-free operation
• Application-specific taper pins: precise fit for 4Runner, FJ Cruiser, and Land Cruiser 200 Series platforms
• Pullout strength: exceeds comparable industry-standard uniball

Specifications

Who This Is For and Isn't

This kit suits owners of 2003–2024 Toyota 4Runner, 2007–2014 Toyota FJ Cruiser, or 2008–2021 Land Cruiser 200 Series vehicles who are running ICON front upper control arms and want a sealed, greaseable, high-angularity joint that holds up to lifted daily driving and off-road use.

The Delta Joint Retrofit Kit fits ICON front upper control arms only. It is not a universal uniball replacement and will not fit other brands' control arms or stock upper control arms. California residents: this product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm (Prop 65).

Common Questions

Will this Delta Joint fit my aftermarket control arms from another brand?

The ICON Delta Joint Retrofit Kit fits ICON front upper control arms only. It uses application-specific taper pins sized for ICON arm geometry and is not compatible with other brands' control arms or with factory upper control arms.

Why choose the Delta Joint over a standard uniball?

A standard uniball leaves its metal-on-metal surfaces exposed to water, salt, and debris, which accelerates wear on a daily-driven vehicle. The Delta Joint adds a zinc-plated housing and a grease seal for corrosion protection, a greaseable design for serviceability, and pullout strength that exceeds a comparable industry-standard uniball, while still achieving the high articulation angles a lifted suspension requires.
