The Carli Suspension Full Progressive Leaf Spring Pack, developed in collaboration with Deaver Leaf Springs—the gold standard in leaf spring manufacturing—is designed to enhance ride quality and performance for your truck. This spring pack is specifically engineered to match Carli’s 4.5″ and 5.5″ front suspension lift systems while maintaining impressive load capacity and increasing wheel travel.
Key Features:
- Replaces factory packs with a 9-leaf main pack and 3-leaf overload for greater spring rate progression.
- Provides a softer unloaded ride with substantial improvements in suspension travel and capacity during compression.
- Supports up to 15″ of wheel travel, delivering smoother cycling on highways, off-road, and while towing.
- Relocated center-pin accommodates up to 38-inch tires (37″ recommended).
- Provides a 1″ rear high stance to perfectly complement Carli’s 4.5″ and 5.5″ suspension systems.
The factory leaf spring packs, with their heavy main springs and immobile lower overload, often result in a jarring ride. Carli’s progressive design, manufactured to exacting standards by Deaver, eliminates these issues by offering smoother suspension operation, massive travel increases, and the ability to maintain impressive capacity as the rear compresses and engages all the springs.
Upgrade your suspension system with the Carli Suspension Full Progressive Leaf Spring Pack to achieve unmatched ride comfort, suspension travel, and durability, all while maintaining a balance of capacity and performance.
