BMW Series 5 E-39 Sedan 12/95-03 Type 5/D 4-6-Cil without autovelation H&R Adjustable Roscada Suspension Monotube coilovers Va 30-70 mm / HA 30-60 mm

General features of the H&R Monotube

• Amortised with an inverted monotube architecture, from the same used in automobile competition.

• The Double Piston with greater section than conventional amortisers with a cylindrical body to ensure better cooling of hydraulic fluid.

• Nitrogen Gas at High Pressure in a camera separated by a double floating piston with multivulse plates that regulates the passage of the oil in an inverse proportion to the work speed of the amortizator.

• Alliance high-quality special metals that give the amortizer a long life and an extreme fatigue resistance.

• The H&R Sports Suspension Moulds are manufactured with special crom silicon steel material returned to the high hardness oil temple and vanadium crom silicon alloys in a cold air process.

• By Muelles progressive it has been developed in a lot of trials. Each step of the manufacturing process is precisely oriented to coupling to the sensitivity of the materials: the correct thermal treatment (300°), the improvement of life through steel ball rolling (Shot peening), the measurement (Pre-setting) and zinc phosphate.

• High Quality HydraulicsThe.The H&R hydraulics used are of high quality and have an extremely high boiling point that makes them very resistant to cavitation with the high working temperatures.

• 5 years guaranteeThe.All these manufacturing processes are verified one by one, which allows you to maintain a high quality standard.
