Carli 17-23 Ford F250/350 4x4 Full Progressive Leaf Spring Pack - L70 - 3in Lift

The L70 designation on these Carli leaf springs means they're built with a specific spring rate designed to handle heavier loads and towing. For your 2017-2023 Ford F250 or F350 4x4, this full progressive leaf spring pack is engineered to provide a 3-inch lift while improving ride quality and control, especially when the truck is working. The progressive nature means the spring rate changes as it compresses, offering a softer ride during normal driving and stiffening up when you need more support under load.

Carli uses a multi-leaf design with carefully selected leaf thicknesses and lengths to achieve this progressive rate. This approach helps to reduce axle wrap and improve traction, which is a common concern with lifted trucks, particularly when towing or hauling. The springs are made from high-strength steel, ensuring durability and consistent performance over time. This full pack replaces your factory springs, offering a complete suspension upgrade that addresses both ride comfort and capability.

When installing this full leaf spring pack, you'll be replacing your entire rear spring setup. It's a significant upgrade that changes the way your truck handles, especially under load. While it provides a 3-inch lift, it's important to consider how this might affect your truck's stance and the potential need for other suspension or driveline adjustments depending on your specific setup and intended use.
