• Use your existing top mounts
• Quality assured via German TüV standard compliance
• Springs are manufactured from highest grade SICR steel.
• Springs are forged using the more reliable 'cold-drawn' method. Some competitors use the hot-forged method of manufacture, this has an adverse effect on the springs' tensile strength: i.e. consistent tension
• Following the forging process, a temperature controlled oil based treatment is applied to the spring to ensure that the required hardness and tension is reached, thus giving full operational effectiveness throughout the springs' entire lifecycle
• The steel is initially treated with Zinc-Phosphate, and finished in an Epoxy Resin to provide effective protection of the spring
• The shock absorbers contain both oil and gas. The gas serves to cool the oil to produce a more consistent operation
• The shock absorbers improve damper performance by 30% compared to a standard unit.
