Icon Delta Joint; Heavy Duty High Angle Retrofit Ball Joint


ICON Vehicle Dynamics is extremely proud to introduce the Delta Joint – a new product that combines the durability of a ball joint with the performance of a traditional uniball. The Delta Joint’s patent pending design was conceived after an interesting pattern of premature uniball wear was recognized by our engineering team. What was peculiar about these cases was that they seemed to be consistently reported from areas in which road salts and other harsh de-icing agents are used throughout the year. After the inspection of several sets of uniballs, it was clear that wear and tear was being accelerated on these components in these particular conditions.

While the industry standard uniball does a great job of allowing the control arms of a vehicle to articulate with little bind, they do have an inherent weakness that leaves more to be desired when used in a daily driven application - exposure to the elements. Whether it be corrosive chemicals used on roadways or the unforgiving dirt and mud that comes with off-road adventure, uniballs allow this debris to build up and eventually work its way into the internals causing wear and possibly failure. Understanding this flaw and the problems that it creates is what sparked the idea of developing a heavy duty, high angle retrofit ball joint which ultimately led to the creation of the patent pending ICON Delta Joint.

What makes the Delta Joint unique is that it brings the best of both worlds to ICON upper control arms with features that make it more robust than a uniball, and at the same time capable of greater angularity than a typical ball joint. A zinc plated housing provides the first layer of corrosion resistance, while a tough grease seal keeps potentially harmful elements out of the inner workings of the joint. Metal on metal construction and a greasable design increase the longevity of the Delta Joint while at the same time allowing for noise-free operation. A carburized taper pin decreases internal friction and further improves corrosion resistance. It is the design of the Delta Joint’s taper pin that allows it to achieve the high angularity required to optimize suspension geometry in lifted applications. Combine these features with the fact that the Delta Joint repeatedly outperformed the traditional 1” uniball in industrial pullout tests and it’s clear that this is a no-compromise addition to the vehicle’s suspension.

The ICON Vehicle Dynamics Delta Joint is currently available in “retrofit kits” for all ICON tubular steel and billet upper control arms, as well as in upper control arm kits that have the Delta Joint pressed into them during the ICON manufacturing process. To retrofit a Delta Joint into a set of ICON upper control arms is a fairly simple operation, however there are tools offered by ICON to make the job easier.


ICON Vehicle Dynamics is so confident in the new Delta Joint that we’re introducing a product-specific warranty to help instill this same feeling in end users. As long as the Delta Joint is used in conjunction with a complete ICON suspension system we will stand behind the product 100% by offering a 5 year limited warranty* against defects or failures.
