The Carli Suspension XXHD Leaf Spring Kit is engineered for 2017-2023 Ford F250/F350 4x4 diesel trucks equipped with 3.5-4.0" axle tubes that require a 3,500-pound constant load capacity. This heavy-duty suspension upgrade is designed for serious work trucks and heavily loaded applications.

Key Features:

• Block-eliminating, full progressive spring pack design provides 1" of lift while improving ride quality
• Engineered for +3,500 pound constant load applications
• Allows fitment of up to 37" tires
• Maintains factory ride characteristics while increasing load capacity
• Complete kit includes main spring pack, bump stop relocation bracket, installation hardware, and u-bolt kit

The progressive spring rate design ensures a comfortable unloaded ride that stiffens appropriately under heavy loads, making it ideal for trucks that regularly haul or tow at maximum capacity.
