Descrizione

As you travel off-road, over long distances, it is likely that your 4WD is equipped with accessories such as: a "bull bar", winch, additional fuel tanks, tow hooks, etc. etc. ... These equipment are essential, to return a safe house. Unfortunately, all these accessories, adding weight to the vehicle, is a mishap for a long period of time. A series of RAW 4x4 springs, in addition to increasing the height, improves the performance of your vehicle in terms of stability, load and towing capacity. From the experience made with heavy vehicles, the 4x4 RAW springs were manufactured, are the production processes, high quality: -First casting steel, with a low amount of carbon, in order to maintain a good elasticity and a very high degree of torsion. - Implemented on precision mandrels: the use of precision mandrels, conditions that all the springs produced, are identical and consistent with the design specifications. - Latest generation thermal treatment - Shot peening treatment: performed in the superficial hammering, performed in cold, by a violent jet of spherical pellets. This treatment causes a superficial compression, which propagates up to a few tenths of a millimeter below the surface. Serve to alleviate the stress accumulated by the metal, during its winding and hardening, as well as improving the distribution of surface tension, increasing resistance: to stress, fatigue and standard stress, combined with a good ductility of the material. -Completely tested: "scratched". The helical springs are subjected to a crushing greater than the limits envisaged, (Lc: block length). At the end of this test, the height of the spring will be permanently set. - Finishing with powder coating. SAMPLE IMAGE
