Dorman Heavy Duty Coil Spring Upgrade Increased Load Capacity

Dorman Heavy Duty Coil Spring Upgrades are replacement coil springs (also called suspension springs) that increase load handling over the vehicle's nominal spring rate. They suit trucks, vans and SUVs that regularly haul, tow or carry heavy loads.

Key Features:

• Increased load handling: The spring rate is higher than the original equipment rate, which helps the vehicle carry heavy loads.
• Better ride-height control: The stiffer springs help reduce sagging and bottoming out under load.
• Several upgrade levels: The line includes heavy duty and severe heavy duty options for different load demands.
• Front and rear applications: The line covers both front and rear positions.
• Direct replacement design: The springs are made as an upgrade for the original coil springs, so they are a simple way to improve load-carrying ability.

Dorman is a well-known supplier of aftermarket replacement and upgrade parts. Choose the specific part number that matches your vehicle and the load level you need.
