What is the lift height provided by this add-a-pack?

This Carli Progressive Add-A-Pack Driver kit is designed to provide approximately 2 inches of lift to the front of your truck. This lift is achieved through the addition of the progressive rate leaf springs.

What is the difference between a progressive and a standard leaf spring?

Standard leaf springs have a consistent rate of stiffness throughout their travel. Progressive springs have a rate that increases as they compress, meaning they start softer and get firmer under load, offering a balance between unloaded comfort and loaded support.

Does this kit include everything needed for installation?

This kit includes the two progressive leaf springs, U-bolts, and nuts. It is designed to integrate with your existing suspension components. Always refer to the manufacturer's installation guide for a complete list of recommended tools and procedures.

Product Details

With this Carli Progressive Add-A-Pack Driver kit, you get a set of two progressive rate leaf springs, two U-bolts, and four nuts. This kit is specifically designed to work with your 2011-2016 Ford F250 or F350 4x4. It's a well-built upgrade that aims to improve your truck's ride quality, especially when carrying loads or towing.

The progressive rate design means the springs offer a softer ride when the truck is unloaded, but they stiffen up progressively as they compress under load. This helps prevent bottoming out and provides a more controlled feel when you're hauling or towing. The springs are made from strong, durable steel, and the included U-bolts are robust enough to handle the added stress. This kit is designed to bolt directly onto your existing leaf spring setup, making installation straightforward for someone familiar with truck suspension work.

This add-a-pack is intended to be installed on the driver's side of your truck. It's a popular choice for owners looking to get a bit more out of their suspension without a full overhaul. Remember to consult your vehicle's service manual or a professional mechanic for specific installation procedures and torque specifications.
