What is the primary benefit of a progressive rate leaf spring?

Progressive rate springs offer a dual benefit: they provide a softer initial ride for everyday driving comfort, but stiffen up as they compress under load. This means your truck can feel more comfortable on the road while still having the capacity to handle heavier hauling tasks without excessive sag.

What does it mean that this kit 'eliminates the factory block'?

Factory trucks often use a block between the axle and the leaf springs to achieve a certain ride height. Removing this block and replacing it with these springs can help reduce the tendency for the rear axle to twist under acceleration (axle wrap) and reduce wheel hop, leading to a more stable driving experience.

What kind of load is required for this kit to work properly?

This kit is specifically designed to work best when there is a constant bedload of 1,500lbs. This load is necessary to engage the progressive rate of the springs as intended, ensuring optimal ride quality and performance for hauling.

Product Details

This is the Carli Rear Progressive Leaf Spring Kit for your 2010-2013 Ram 2500 or 3500 diesel 4x4. If you're looking to improve your truck's rear suspension performance, especially when carrying a consistent load, this kit is designed to make a significant difference. These springs are made by Deaver, a well-known name in suspension, and are built to provide a comfortable ride on the street while still being able to handle a 1,500lb constant bedload. This makes them a great option if you frequently use your truck for hauling, like with mid-size slide-in campers.

One of the key benefits of this kit is how it helps manage axle wrap and wheel hop, especially by eliminating the factory block. This can lead to a more stable and predictable feel when accelerating or under load. The progressive rate design means the springs offer a softer initial feel for everyday driving, but stiffen up as they compress to support heavier loads. This setup is capable of achieving up to 15 inches of suspension travel when used with the factory shackle, contributing to a smoother ride over rough terrain and maintaining a slight rear-high stance when paired with Carli's 3-inch lift systems.

It's important to note that this kit requires a constant bedload of 1,500lbs to function as intended. This is a crucial detail for achieving the desired ride quality and performance characteristics. The kit is designed as a direct replacement for the factory leaf springs, aiming for a straightforward installation process, though it's always recommended to consult the manufacturer's instructions for specific details.
