2003–2009 Dodge Ram 2500/3500 4WD Diesel Carli 2.75–3” Multi-Rate Front Coil Springs

Upgrade the ride quality, handling, and stance of your 2003–2009 Dodge Ram 2500 or 3500 with the Carli Multi-Rate Front Coil Springs. Designed specifically for diesel-powered 4WD trucks, these premium front coils deliver a smoother ride on-road while maintaining the control and stability needed for towing, daily driving, and off-road use.

Unlike traditional linear-rate springs, Carli’s custom multi-rate design allows the suspension to stay soft and compliant over small bumps while progressively firming up during aggressive driving, hard braking, and rough terrain. The result is improved ride comfort without sacrificing performance.

Ride Quality & Performance

Carli’s multi-rate spring technology uses varying coil spacing throughout the spring to create a progressive spring rate. During normal driving, the springs remain soft and responsive for improved comfort and reduced harshness. As suspension load increases, the spring rate progressively stiffens to improve vehicle control, reduce body roll, and enhance stability.

This design provides a noticeable improvement over factory and standard aftermarket coil springs, especially on lifted or heavily used trucks.

Construction & Durability

Each spring is engineered to withstand demanding use both on and off-road. The springs are shot-peened and hydraulically pre-set to help reduce fatigue and maintain consistent ride height over time.

The durable black powder-coated finish helps protect against rust, corrosion, and harsh weather conditions.
