What is the benefit of a progressive rate leaf spring?

Progressive rate leaf springs offer a dual benefit. They start with a softer spring rate at normal ride height for improved comfort on everyday driving. As the suspension compresses further, additional leaves engage, increasing the spring rate to handle heavier loads and prevent bottoming out.

Does this kit include everything needed for installation?

This kit includes the full-length progressive-rate spring packs. It is designed to eliminate the factory block, but you should refer to the manufacturer's installation instructions for a complete list of any additional hardware or components that may be recommended or required for proper installation.

How does this kit affect my truck's stance and towing capacity?

These springs will provide a 1-inch rear lift and are designed to maintain a slight rear-high stance, especially when paired with Carli's 3-inch lift systems. They are rated for a "Light" 3/4-ton cargo and tow capacity, offering a balance between comfort and utility.

About this part

Product Details

Carli Suspension is known for building robust suspension components for trucks, and this rear progressive leaf spring kit is a prime example of their focus on improved ride quality and capability. If you're looking to enhance the rear suspension on your 2010-2013 Ram 2500 or 3500 with a gas engine, these springs are designed to offer a more comfortable ride across various terrains while still handling hauling and towing duties.

These aren't your average leaf springs. They're full-length packs, custom-built by Deaver Spring exclusively for Carli. The key is their two-stage progressive-rate design. This means they start with a softer initial rate at ride height, which really smooths out bumps and imperfections on the road. As you add weight or encounter larger impacts, more leaves engage, providing a firmer support. This design helps maintain a slight rear-high stance when paired with Carli's 3-inch lift systems and allows for an impressive 15 inches of suspension travel when using the factory shackle. By eliminating the factory block, these springs also help minimize axle wrap and wheel hop, giving you more stable power delivery.

This kit is specifically designed to fit 2010-2013 Ram 2500 and 3500 4x4 models with the Hemi V8 engine and a 3.5-inch axle tube. They offer a "Light" 3/4-ton cargo and tow capacity, meaning they're built to handle your gear and trailer without excessive sag, while still prioritizing a comfortable driving experience whether you're on pavement or exploring off-road. You'll get a 1-inch lift from these springs, contributing to a balanced stance.
