Carli 05-23 Ford F250/350 4x4 Heavy Duty Full Progressive Leaf Spring Pack - L18HD - 1in Lift

This is the Carli L18HD Full Progressive Leaf Spring Pack, designed for 2005-2023 Ford F250 and F350 4x4 trucks. If you're looking to improve your truck's ride quality and load-carrying capability, especially when towing or hauling heavy loads, this spring pack is a solid choice. It's engineered to provide a more comfortable ride when the truck is empty while still offering the support needed for demanding work or towing situations. The progressive rate design means the springs offer a softer initial engagement for better comfort over bumps, and then stiffen up as they compress under load, preventing bottoming out.

Carli has built these springs with a focus on durability and performance. They utilize a multi-leaf design where each leaf is carefully selected and tapered to work together. This approach allows for a more controlled flex and better weight distribution compared to a stock setup. The pack is designed to provide approximately a 1-inch lift over stock height, which can help level out the stance of your truck, especially if you're carrying extra weight in the rear. The springs are made from high-strength steel, ensuring they can handle the stresses of daily driving, towing, and off-road use. Installation involves replacing your factory leaf springs, and while it's a significant suspension upgrade, it's a direct bolt-on process that doesn't require welding or cutting.

When installing these springs, it's important to follow the manufacturer's recommended procedures to ensure proper alignment and function. You'll want to torque all fasteners to spec once the vehicle's weight is on the suspension. This spring pack is a substantial upgrade for owners who regularly tow trailers, haul equipment, or simply want a more compliant and capable rear suspension for their Super Duty truck. It's a well-built component from Carli, known for their attention to detail in suspension tuning.
