What is the intended use for the Carli XXHD Leaf Spring Kit?

This kit is designed for trucks that consistently carry a constant load of 3,500 pounds in the bed, such as those equipped with cab-over campers or heavy work setups. It is not intended for unloaded daily driving.

What is included in the Carli XXHD Leaf Spring Kit?

The kit includes the XXHD full replacement leaf spring packs, new U-bolts for installation, and rear bump stop drops. These components work together to provide the lift and load-carrying capability.

Will this kit affect my truck's ride quality when unloaded?

The XXHD springs are optimized for carrying a constant 3,500-pound load. While they offer a progressive spring design, the ride quality when the truck is unloaded may differ from stock due to their heavy-duty application.

About this part

Product Details

If you're running a constant 3,500 pounds in the bed of your 2017-2023 Ford F-250 or F-350 Super Duty, like with a cab-over camper or a fully loaded work setup, the Carli XXHD Leaf Spring Kit is built for that specific scenario. These aren't meant for daily driving without a load; they're engineered to handle serious weight day in and day out.

This kit replaces your factory leaf springs with a full progressive spring pack that eliminates the need for lift blocks, while still providing a 1-inch lift. The progressive design means the springs offer a more controlled ride under load, adapting to the weight you're carrying. This setup is also designed to allow you to fit up to 37-inch tires, giving you more ground clearance and capability for off-road adventures or demanding work sites. You'll get new U-bolts and rear bump stop drops included to ensure a complete installation.

This kit is specifically designed for 4x4 diesel models and requires the 3,500-pound constant load to function as intended. It's a well-built solution for those who consistently haul heavy loads and need their suspension to perform reliably under pressure.
