- Enhanced Load - Bearing Capacity: Our THOCAC variable - rate heavy - duty rear coil springs kit is specifically designed for 2009 - 2018 Ram 1500 (both 2WD and 4WD models). It offers an extra 70% load capacity (up to 1100 pounds) at the stock ride height. This means you can carry heavier loads such as equipment, cargo, or passengers without worrying about overloading the vehicle's suspension, and the variable - rate feature ensures optimal performance under different load conditions
- Vehicle Compatibility: These coil springs are a perfect fit for 2009 - 2018 Ram 1500 trucks. They are engineered to work seamlessly with the existing suspension system of your vehicle, ensuring a hassle - free installation process. You can trust that these variable - rate springs will integrate well with your vehicle's design and adapt to various driving scenarios
- High - Quality Materials: Crafted from top - notch materials, these rear coil springs with variable - rate design exhibit excellent strength and durability. The springs offer high strength, with a tensile strength ≥ 1225 MPa (125) and a yield strength under specific conditions ≥ 1080 MPa (110). This enables them to withstand the increased stress caused by the additional load and large stresses and loads in general. Good hardenability makes the overall performance of the springs more stable compared to traditional materials. Moreover, the corrosion resistance is increased by 35%.The variable - rate functionality further enhances their adaptability
- Maintained Performance on Various Terrains: Even when carrying a heavier load, the extra 70% load capacity provided by these variable - rate springs helps maintain the stock ride height. This ensures that your Ram 1500 can still navigate various terrains with ease. The variable - rate design allows the springs to adjust their stiffness according to the road conditions and load, improving the vehicle's passability and handling on rough roads or uneven surfaces
- Aesthetic and Practical Appeal: Besides the functional benefits, these black - colored variable - rate coil springs add a sleek and professional look to your Ram 1500. The 2 - piece kit provides a complete solution for the rear suspension, combining both practicality and aesthetics to enhance your overall driving experience. The variable - rate feature not only improves performance but also gives your truck a more advanced and high - tech feel
- Due to the physical manufacturing process, the variable-rate springs are actually a bit taller than the original vehicle springs. However, when under stress, the variable-rate part will compress downward preferentially and can reach the level of the original factory height after a slight load. Therefore, if your vehicle never has a cargo-carrying requirement, your vehicle will be raised by 1 to 2 inches.
The product is a set of rear heavy-duty coil springs designed specifically for 2009-2018 Ram 1500 2WD and 4WD trucks with an extra 70% load capacity. Made in the United States, these painted springs are 1" thicker and offer a 70% lift capacity, providing enhanced performance and durability for your vehicle. The package dimensions are 20.6 x 12.9 x 6.6 inches, and the springs weigh 35.2 pounds each, ensuring a sturdy and reliable upgrade for your vehicle's suspension system.
