What is a progressive leaf spring and why is it beneficial?

A progressive leaf spring has a spring rate that changes as it compresses. It starts softer for a more comfortable ride when the truck is empty, and gets stiffer as more weight is added. This design offers a better balance between unloaded comfort and load-carrying capability compared to traditional springs.

What is included in this full leaf spring kit?

This kit includes a complete set of progressive leaf springs designed to replace your truck's factory rear springs. It is intended to be a comprehensive solution for upgrading your rear suspension.

Will this kit affect my truck's towing or hauling ability?

Yes, the progressive design is specifically intended to improve your truck's ability to handle loads. The springs stiffen under compression, which helps support the weight of towing or hauling more effectively than stock springs.

About this part

Product Details

Carli Suspension is known for building serious suspension components for trucks, and this full progressive leaf spring kit for your 2003-2012 Ram 2500 or 3500 is a prime example. If you're looking to lift your truck by about 4 inches while significantly improving its ride quality and handling, especially when carrying loads or towing, this kit is designed to do just that. These aren't just simple lift blocks; they're a complete replacement for your factory rear leaf springs, engineered to offer a much more comfortable and capable ride.

What makes these springs special is their progressive rate design. Unlike traditional springs that have a constant rate, progressive springs have varying rates. This means they start out softer for a more comfortable ride when the truck is unloaded, but get stiffer as they compress under load. This is ideal for trucks that see a lot of varied use, from daily driving to hauling heavy equipment or towing a trailer. The kit includes everything needed to replace your stock springs, ensuring a comprehensive upgrade. The springs themselves are well-built, designed to handle the demands of a heavy-duty truck while providing an improved ride experience.

When installing this kit, you're replacing your entire rear spring setup. It's a substantial upgrade that changes how your truck handles both on and off-road. You'll notice a difference in how the truck absorbs bumps and handles weight. Make sure you have the necessary tools and potentially an extra set of hands for this installation, as it involves significant suspension work. This kit is a solid choice for Ram owners looking for a significant improvement in ride comfort and load-carrying capability.
