Designed and built by Deaver Suspension, these Carli Rear Leaf Springs provide 15" of increased wheel travel, 3" of rear lift, and deliver smoother suspension cycling over terrain without the use of lift blocks with only a slight reduction from a standard 3/4-ton load capacity. These leafs feature a 9-leaf main and a 3-leaf overload for less jarring, more mobility in the lower overload, and improved spring rate progression.

- Compatible with 3.5" axle tube
- 3" rear lift, provides a 1" rear high stance on Carli 4.5"/5.5" Leveling Suspension Systems
- Delivers "Light" 3/4-ton cargo/tow capacity, full capacity attainable with long-travel airbags
- Block-eliminating, full progressive spring pack
- Includes new U-bolts, rear bump stop drops
- Allows the use of 37" tires
From Carli Suspension
Carli Suspension worked in conjunction with Deaver Leaf Springs to design a leaf spring pack to match our 2.5″ and 4.5″ Suspension Lifts while providing a much more predictable and supple ride with only a slight reduction from a standard 3/4-ton load capacity. The factory leaf spring packs have 2-4 heavy main springs and an immobile lower overload making for a jarring ride; replacing them with our 9-Leaf main pack and 3-Leaf overload provide much more spring rate progression. This makes for a softer unloaded ride, massive suspension travel increase and impressive capacity as the rear end compresses engaging all the springs.
The Carli Suspension Super Duty Full Spring Pack is designed and built to our specifications supporting up to 15″ of wheel travel. The center-pin is relocated to accommodate (up to) 38 inch tires, 37″ recommended, and levels the rear perfectly to match our 4.5″ front suspension systems, respectively. This spring pack delivers smoother suspension cycling in all situations: highway, off road and towing.
