Carli Full Progressive Leaf Pack - For Leveling Systems - Heavy Duty

If you're running a heavy-duty work truck that consistently carries a significant load, like a full toolbox or other equipment, Carli's HD Full Replacement Leaf Springs are built to handle that demand. These springs are specifically engineered for trucks that maintain a constant 1,000 pounds in the bed. It's important to understand that this is not a spring pack intended for unloaded use; it requires that 1,000-pound load to sit at its proper height and function as designed.

Compared to Carli's standard leaf springs, these HD versions feature a much heavier spring rate. This increased rate, combined with the design for a higher center of gravity, means they work best when paired with performance shocks. Carli recommends their 2.5" remote reservoir shocks with custom valving to ensure optimal control and a comfortable ride quality, even under load. This setup provides about 1" of rear lift, which is intended to complement Carli's 2.5" leveling systems and allows for clearance of up to 37" tires.

When you order this kit, you'll receive the full replacement leaf springs, rear bump stop drops, and a complete u-bolt kit, making installation more straightforward. Remember, these springs are designed to perform best when the truck is carrying its intended load.
