KIT 4 FRONT + REAR SPRINGS +5CM SUZUKI JIMNY (FOR CARS WITH WINCH) made entirely in Italy with high quality steel, raised by 5 cm compared to the original set-up.Variable-pitch springs, meaning the distance between the coils is not constant but varies along its length, determine the stiffness of a spring with the same material and wire diameter, based on the number of coils and their pitch. A progressive spring allows for more coils than a traditional spring, resulting in a much softer ride. The variable-pitch coils progressively stiffen the spring during compression, thus obtaining an extremely soft, comfortable ride that follows the contours of the terrain, yet is very stable on the road.
