9. Shocks are an extremely important part of any rig. As you might have guessed, the 2 1/2-ton Rockwells are far from light. We needed a shock with a bit of adjustment so we could dial in the ride and control the best we could. The Pro Comp MX-6 with fluid reservoirs was the perfect fit for what we were looking for. The MX-6's wide adjustment range and easy-to-use control knob takes out the bounce, and the extra fluid capacity prevents the shocks from fatiguing, as the suspension is sure to get punished as we slam from one mud hole to the next.
