Smooth Street Manners Without Giving Up The Weekend Trail

If your RAM 3500 is a daily driver during the week and a trail rig on the weekend, the stock leaf springs are not really built for either job. Carli Suspension had Deaver Spring Mfg build these full length progressive spring packs specifically for this truck, and the goal was a balance of on and off road comfort. They use a two stage design, so the initial spring rate is softer at ride height, which is what gives you a smoother and more comfortable ride on pavement. As you load the truck or get deeper into the travel, the pack stiffens up so you still have a respectable weight capacity for work. The springs add 1 to 2 inches of rear lift, and that keeps a slight rear-high stance when you pair them with Carli's 3 inch systems. They also work to minimize axle wrap and wheel hop, which is the shudder and hop you feel when a heavy truck puts power down on a rough surface. With the factory shackle you get up to 15 inches of suspension travel, so the truck can actually use the suspension on a trail. For a diesel 3500 that has to work all week and play on weekends, this pack is built for exactly that mix.
