When it comes to coil springs, understanding the differences between Compression, Extension, and Torsion springs is crucial for selecting the right type for your needs. Each of these springs performs unique functions and operates differently under various forces. Whether you are an engineer designing complex machinery, a maker working on innovative projects, or simply someone seeking a reliable spring for a specific application, knowing how to choose the right spring can make all the difference in performance and longevity.
Also known as progressive rate springs, these springs have coils that aren’t evenly spaced out. The spring rate changes dynamically as the spring is compressed, allowing it to have different spring rates. The coils that are spread apart provide a comfortable ride under normal conditions and when the vehicle is loaded, those coils become compressed. The tighter wound coils help prevent the vehicle from sagging excessively. Ideal for multipurpose vehicles used as daily drivers as well as hardworking activities like towing or hauling loads, variable rate coil springs can help reduce harshness and pitch and roll, and help avoid bottoming out under various levels of load conditions.
