Carli Suspension has officially raised the bar again with their 6" Radius Arm System for Ram HD's!

If you've ever owned a late model Dodge Ram with a six inch or taller lift kit, you understand that there are some serious drawbacks in terms of the performance of the suspension. Basically, the ride quality is extremely poor and the truck actually loses a great deal of its articulation resulting from the control arms being at an extreme downward angle. Unfortunately, most truck owners just take this fact as being part of owning a lifted truck. IT DOESN'T HAVE TO BE THIS WAY!

Here is where long arms (control arms that mount further back on the frame rail to reduce the angle at which they meet the axle) come into play. A long arm system will drastically increase the front suspension's handling capabilities by minimizing or eliminating the bind that standard control arms put the front axle in. There are two main types of long arm systems for Dodge Rams. The first, and most popular for street driven trucks, is a system that has an upper and a lower bar, similar to the factory, just longer. This type of system works pretty well, but it limits the amount of articulation available simply because the upper bar cannot travel very far upward before it runs into the bottom of the frame rail. The second type of system is what many would consider a radius arm design. The radius arm is a single beam that forks at the axle, and allows for considerable articulation. However, traditional radius arms have a drawback for street trucks in that it cannot control axle dive as well as a traditional upper and lower bar system. So, what system is better? Well, it depends on what you use your truck for (in most cases). This was not good enough for Carli, they wanted to have their cake and eat it too, so, they developed a system that would give the best of both worlds, ride quality, streetability, and articulation.

Presenting the Carli 6" Radius Arm System. Now, what makes this system different is the addition of a custom axle control shock. Basically, Carli engineered a radius arm system, robust in every way including internal gusseting to eliminate flex, and then added a nitrogen charged shock as the upper mount on the drivers side. But why would you do this? As mentioned earlier, the disadvantage of a radius arm system is a condition called "axle dive." The most common way to describe axle dive is when you hit the brakes, and the truck wants to veer to one direction because the axle rolls downward on one side more than the other. To combat this, the axle control shock is charged with 200 psi of nitrogen that puts a constant push on the axle, eliminating axle dive. We have personally fitted this system on several of our own trucks, and we can attest 100% that this system will completely change the driving characteristics of any lifted truck for the better.

The Carli 6" Radius Arm System is available for all 2003-2013 Dodge Ram 2500 and 2003-2012 3500's with a six inch lift. We have installed this system onto a truck with a 4.5" lift, and can say that it works flawlessly, even though it is not a 6" kit.

This system is also available in two different crossmember configurations. For most street trucks, they offer their standard multi-piece crossmember which is plenty strong. But for those that either want the ultimate in strength, or are off-roading the truck, you will want to upgrade to their heavy duty one piece configuration.
Due to the size and weight of this system, we cannot offer free shipping.
