Total Chaos Arm Kit - Build Your Own Mid-Travel PackagePosted in How To on November 1, 2008 Comment (0)
Since the '07-and-later Chevy Silverados moved from torsion-bar 4wd and coil-sprung 2wd suspensions to a shared coilover-type suspension, it has opened up the possibilities for the aftermarket to start making more performance products that will adapt into the factory locations of both suspensions. More easily can you now adapt aftermarket coilover shocks or aftermarket arms to your stock Chevy to improve the ride and travel of your truck.
One of the first to recognize the potential improvements in the Chevy was Total Chaos. Soon after the truck came out, Total Chaos had a new upper control arm available that fits onto both the 2wd and 4WD Chevy 1/2-tons. Using the coilover (or a spacer kit), you can lift your Silverado up to 2 inches while still staying within correct camber angles. On top of that, the Total Chaos upper control arm allows for 2 more inches of droop in your suspension, offering more travel to both 2wd and 4wd stock trucks.
With an upper A-arm available, Icon Vehicle Dynamics worked with SoCal SuperTrucks and Total Chaos to offer some package upgrades as well.
Available through either Total Chaos or SoCal SuperTrucks, owners can one-up their upper control arm kit and add a 2- to 3-inch-lift coilover to increase suspension travel to around 9 inches. And if you're looking for a bit more height out of your 2wd Chevy, SoCal SuperTrucks offers the Total Chaos upper control arm and the Icon coilover in a mid-travel package that includes a 3-1/2-inch CST lift spindle and rear block.
The truck we operated on was 2wd, and we got the entire mid-travel package in order to fit a set of 35-inch Toyos under some fiberglass front fenders. SoCal SuperTrucks' website says the package will clear 35-inch tires, but if you are stuffing the truck hard, then the front fiberglass is highly recommended.
With the 2wd Chevy we got to try out the entire mid-travel package on, the front kit performed nicely, especially considering that it was just a couple replacement parts and not a full long-travel kit. The shock valving was right on, and when combined with the increase in travel, the suspension really soaked up some good hops nicely. Even with the tires in the air, we didn't bottom out the front. We did, however, rub the tires on the rear fenders a bit during jump landings. And the rear clearly was not keeping up with the front of this truck. We wish this truck owner had opted for the full leaf pack instead of just a block, so we could really see what this Chevy was capable of.
