Carli Suspension CS-DMRC-14-R2 Premium Multi Rate Coil Springs for the Dodge Ram 2500 are designed to withstand full coil bind and bounce right back to their original height. Carli Suspension's RAM Rear Coils were meticulously designed to tackle various problems associated with both factory and aftermarket coil springs. Carli Suspension carefully selected a dedicated spring rate and heavy-duty wire diameter to achieve a softer spring rate than the stock coils while ensuring long-lasting strength and resilience for any activitity you throw at it. Each set is tailored to fit perfectly on the driver and passenger sides, ensuring a soft ride, precise fitment, and improved wheel travel, delivering the performance anyone would desire.

Initially, compressing these springs for the first few inches is effortless. As you exert additional force, the coils gradually draw closer together. Beyond a specific threshold, the coils located in the lower quarter of these springs begin to make contact with one another, ultimately rendering that section inactive or "dead," resulting in increased spring stiffness. The greater the force you apply to our multi-rate spring, the higher the rate of stiffness. Consequently, these springs exhibit compliance to minor road imperfections, yet deliver control when required during off-road adventures, aggressive braking, and sharp turns. These springs enable you to achieve peak performance during spirited driving while maintaining a smooth and comfortable ride during regular use.
