Heavy Duty Rear Springs - RAM 1500 2019-2023

CargoMaxx XHD Heavy Duty Variable Rate Coil Springs (Pair)

Upgrade your suspension with CargoMaxx XHD Heavy Duty Variable Rate Coil Springs, engineered for vehicles that regularly carry heavy loads or tow trailers. These premium springs provide significantly greater load-carrying capacity while maintaining a comfortable ride when the vehicle is unloaded.

Unlike standard replacement springs, CargoMaxx XHD springs feature a progressive (variable) spring rate, allowing them to adapt to changing loads. During normal driving they deliver a comfortable ride, while under increased weight they become progressively stiffer to improve vehicle stability, reduce body roll and maintain the correct ride height.

Perfect for pickups, SUVs, commercial vehicles, campers and work trucks that frequently operate under demanding conditions.

Features

• Heavy Duty variable-rate (progressive) coil spring design
• Sold as a pair
• Designed to support up to 70% more load while maintaining approximately the original loaded ride height

Progressive Spring Technology

CargoMaxx XHD springs use a variable-rate (progressive) design, meaning the spring rate changes as the spring compresses.

Benefits of Progressive Springs

• Comfortable ride quality when driving unloaded
• Increased support as vehicle weight increases
• Reduced body roll and suspension squat
• Improved steering response under load
• Better overall vehicle control during towing or hauling

This makes progressive springs the ideal choice for vehicles that alternate between everyday driving and carrying heavy loads.

Designed for Heavy-Duty Applications

CargoMaxx XHD coil springs are an excellent upgrade for vehicles used for:

• Heavy towing
• Commercial use
• Utility vehicles
• Pickup trucks
• SUVs
• Camper conversions
• Motorhomes
• Vehicles carrying tools or permanent equipment

The springs are engineered to maintain a ride height approximately 1 inch above the standard loaded height (unless otherwise specified for a particular application). Actual unloaded ride height may vary depending on the vehicle's engine, trim level and equipment.
