This pair of rear springs are made in Italy with 52SiCrNi5 high quality steel in compliance with the UNI EN 10089 standard, they are longer than the original ones, reinforced with progressive effect.These springs raise the vehicle by 5cm compared to the original trim and mount without any modification on all Suzuki Vitara until 1999, both with gasoline and diesel engines, in the top menu you can choose the correct calibration desired in order to configure the trim according to your needs.At the top of the page you can choose the type of load of the springs to adapt them to your use: SOFT for use entirely off-road without load on the rear, you will have maximum off-road performance, excellent road stability but if you load the rear suspension is significantly lowered, incorrect use prematurely snerva; STANDARD with a very similar setting to the original trim, excellent offroad performance and very stable on the road, ideal for multi-purpose use of the vehicle; REINFORCED with reinforced calibration compared to the original, ideal for the towing of trolleys or the use of the vehicle mainly with load in the boot over 150kg. In the technical data sheet the operation of a variable pitch spring is explained.The springs are built in Italy by a company certified by TÜV according to the UNI/ISO 9001:2015 standard.
The progressive springs, unlike traditional ones, have a variable pitch, ie the distance between the coils is not constant but varies along its length, the stiffness of a spring equal to the material and diameter of the wire is given precisely by the number of spire and by their step.A progressive spring allows to insert more coils with respect to a traditional spring, resulting much softer, the coils with variable pitch during compression harden the spring progressively obtaining an extremely soft, comfortable and able to copy the ground but very stable on the road.The main advantages in off-road of a progressive spring: greater ability to copy the terrain; greater excursion at equal length compared to a traditional spring; very stable in the lateral passages because crushing it stiffens; most absorption of sudden obstacles, as stiffens progressively brakes a possible obstacle (boulders, roots, etc.) without getting to buffer. The main advantages on the road of a progressive spring: very stable on fast sections; very more comfortable than a traditional spring thanks to the high number of turns; it reduces the rolling in the corners to a minimum as crushing progressively stiffens.
