When venturing off-road for long distances, load-bearing accessories like a bull bar, winch, and long-range fuel tank are essential for a safe return home. However, these accessories add weight to your vehicle. Original coils are not designed to handle this extra load, which may lead to sagging over time.
A set of RAW 4×4 coil springs will greatly enhance your vehicle’s ability to handle additional weight while improving overall performance in stability, load-carrying, and towing capabilities.
RAW 4×4 springs have been manufactured using the following high-quality material & processes:
By pairing your coil springs with RAW 4×4 shock absorbers, you create a fully integrated suspension system. It’s equally important to ensure your coils are matched to the accessories currently on your vehicle. With many new 4×4 models featuring an independent strut front end, it’s crucial to avoid over-specifying or under-specifying your springs, as this can cause the front end to sit too high or too low. Not only does this affect aesthetics, but it can also lead to damage to other components like struts or CV joints.
In linear rate springs the coils are equally spaced and the wire is of a constant diameter throughout. These coils exert a constant rate of force per distance traveled. This means that the load applied to the spring will be proportional to the amount of distance it travels based on the spring rate of your linear spring.
2 different linear rates in the one coil. The coils in a variable rate spring are wound so that they are not equally spaced this is how the variable rate is achieved. This allows for 2 different linear spring rates in the one coil, these different rates depend on how much the spring is compressed. As the spring rate is compressed the heavier linear spring rate is engaged. The benefit of this type of spring is that when a heavier load is being carried the ride height of the vehicle will not drop as much as it would with linear rate springs.
The progressive spring rate is achieved by a combination of differences in wire diameter and coil spacing. The benefit of this type of spring is that the spring rate changes exponentially as the spring is compressed, this allows for a smoother transition in spring rates giving a more comfortable ride even when carrying heavier loads.
