ICON 614561 Non-ICON UCA 1" Delta Joint Kit for 03-24 Toyota 4Runner/FJ Cruiser

Vehicle Fitment

• 2003-2024 Toyota 4Runner (All Trims, 4WD)
• 2007-2014 Toyota FJ Cruiser (All Trims, 4WD)
• 2008-2021 Toyota Land Cruiser 200 Series (All Trims, 4WD)
• 2003-2009 Lexus GX470 (All Trims, 4WD)
• 2010-2023 Lexus GX460 (All Trims, 4WD)

Fitment Notes

• Designed for use with non-ICON upper control arms (UCAs) that utilize a 1" uniball - not for use with ICON brand UCAs (use ICON part #614551 for ICON UCAs).
• Replaces all WSSX16, AWX16, WC16, WE16, WSSB16, WR16, and ABW16 uniballs with a 2.125" outside diameter and 1" height.
• Retrofit kits are designed for use only with stock-length upper control arms. Extended or custom-length UCAs require fitment verification.
• Fitment verification is the duty of the installer. Failure to cycle the suspension and check for bind issues may lead to component failure and/or injury. Professional installation is required.
• Toyota Land Cruiser 200 Series production ended after 2021; no 2022+ Land Cruiser 200 fitment exists.
• Lexus GX460 was replaced by the GX550 (new platform) for 2024+; this kit does not fit the 2024+ GX550.

Features

• Patented Delta Joint technology (U.S. Pat. 10,731,700) combines the durability of a traditional ball joint with the high-angularity performance of a uniball for superior off-road capability
• Sealed zinc-plated housing provides corrosion resistance against road salts, moisture, and trail debris - a significant upgrade over exposed uniball designs
• Grease seal keeps contaminants out of the internal workings, extending service life in harsh off-road and daily driving environments
• Metal-on-metal internals paired with a Zerk grease fitting allow for routine maintenance and long-term, noise-free operation
• Capable of the high angularity required for lifted applications, allowing for greater suspension travel without bind
• Carburized taper pin delivers increased corrosion resistance, reduced internal friction, and minimizes the risk of thread galling during installation and removal
• Pullout strength exceeds that of comparable industry-standard 1" uniballs for enhanced safety and reliability under load
• Application-specific taper pins engineered for precise fitment across the full range of compatible Toyota and Lexus platforms

Product Description

The ICON 614561 Non-ICON UCA 1" Retrofit Delta Joint Kit is engineered for Toyota and Lexus truck and SUV owners running aftermarket upper control arms with a 1" uniball who want to upgrade beyond the limitations of a traditional uniball design. Standard uniballs are effective at reducing suspension bind and allowing articulation, but their open, unprotected design makes them vulnerable to the elements - road salt, mud, water, and debris accelerate wear and can lead to premature failure. The Delta Joint solves this with a sealed, zinc-plated housing and a grease-retaining seal that locks contaminants out while keeping lubrication in, delivering a joint that outlasts conventional uniballs in both daily driving and serious off-road use.

This kit is specifically designed for use with non-ICON brand upper control arms that accept a standard 1" uniball with a 2.125" outside diameter and 1" height. It fits a wide range of compatible aftermarket UCAs across the Toyota 4Runner (2003-2024), FJ Cruiser (2007-2014), Land Cruiser 200 Series (2008-2021), Lexus GX470 (2003-2009), and Lexus GX460 (2010-2023) platforms. Each kit includes two Delta Joints - one for each side - along with retaining rings and anti-seize compound for a complete installation. Use with stock-length upper control arms only, and always cycle the suspension post-installation to verify full range of motion without bind.

ICON Vehicle Dynamics developed the Delta Joint as a direct response to real-world and race-tested feedback on the durability limitations of traditional uniballs in daily-driven lifted applications. The patented design brings together metal-on-metal construction, a greasable Zerk fitting for ongoing maintenance, and a carburized taper pin that resists corrosion and thread galling - all in a package that delivers pullout strength exceeding comparable industry-standard uniballs. For off-road enthusiasts who demand the articulation of a uniball without sacrificing longevity, the ICON 614561 is a direct, high-performance upgrade that requires no modifications to the knuckle and installs with standard tools.
