What is the purpose of the Delta Joint in the upper control arms?

The Delta Joint is a heavy-duty, high-angle ball joint that combines the durability of a uniball with the greater angularity of a typical ball joint. It features a zinc-plated housing and a grease seal to keep out contaminants, and its metal-on-metal construction with a greaseable design increases longevity and ensures noise-free operation.

How does the 'Bump Zone' feature on the shocks improve performance?

The internal 'Bump Zone' creates an additional 20% of damping force as the shock approaches full compression. This extra force helps prevent harsh bottom-outs and provides better control when the suspension is compressing rapidly, such as when hitting large bumps or during aggressive off-road driving.

What is the benefit of the remote reservoir on the shocks?

The remote reservoir increases the duration of consistent damping performance by keeping the shock at a cooler operating temperature. This is especially important during heavy use or prolonged off-road driving, as it helps to reduce shock fade and maintain optimal suspension control.

Product Details

ICON Vehicle Dynamics is well-known for making serious suspension components for trucks and Jeeps. If you're looking to get more out of your 2020-2022 Chevrolet Silverado 2500 HD, especially when you take it off the pavement, this complete shock and upper control arm system is designed to do just that. It's built to give your truck outstanding performance when you're exploring trails and a smooth, comfortable ride when you're just driving around town.

This system includes ICON's Vehicle Specific (V.S.) 2.5 Aluminum Series shocks, which are tuned specifically for your truck's length and damping needs. They feature a remote reservoir to keep them cooler during heavy use, reducing shock fade and maintaining consistent damping. An internal 'Bump Zone' adds 20% more damping force as the shock compresses, helping to prevent harsh bottom-outs. The included upper control arms are made from CNC machined 6061 billet aluminum, offering a great balance of light weight and strength. They feature ICON's unique Delta Joint, a heavy-duty, high-angle ball joint that combines the durability of a uniball with the greater angularity of a ball joint, all while being protected from the elements and greaseable for longevity. These arms also allow for additional camber and caster adjustment, which is crucial for getting your alignment dialed in perfectly after a suspension upgrade, and they work with the shocks to increase wheel travel.

This kit is 100% rebuildable and revalveable, meaning you can service and tune these shocks for years to come. The system is designed for a direct fit, using a vehicle-specific taper pin for the upper control arms to ensure an OE-like installation. FK Rod End 7/8” heim joints are used for smooth operation and precise alignment adjustments.
