Carli Full Progressive Leaf Pack - For Leveling Systems - Heavy Duty
The Carli Heavy Duty Full Progressive Leaf Spring Pack is designed for trucks running a constant 1,000 lb bed load, making it ideal for work trucks equipped with toolboxes, welders, or overland setups. Built in collaboration with Deaver Spring, this system replaces the harsh factory leaf pack with a fully progressive design that significantly improves ride quality, control, and suspension travel. These springs are not intended for unloaded use and require the constant weight to achieve proper ride height and performance.
Engineered to pair with Carli 2.5" leveling and suspension systems, this HD spring pack delivers smoother suspension cycling across highway driving, off-road terrain, and towing applications. The multi-leaf progressive design increases articulation while maintaining stability under load, making it a versatile upgrade for demanding applications.
