All coil springs related designs are designed on an advance CAD program. State of the art design programs are crucial when designing linear and progressive rate springs to ensure laden and unladen spring rates are correct to provide the best possible ride comfort and handling.
'SUP-9' is a new generation High Strength Performance Spring Steel which with-stands higher operating stresses and has superior resistance to sag and improved corrosion fatigue properties.
WHEREAS THE HEAVY DUTY 4WD COIL SPRINGS WITH 17MM & ABOVE WIRE DIAMETER USE 'X5K' SPRING STEEL FOR IMPROVED TO
Dr. Nano coil springs are ‘cold wound’ on most advanced 5-axis CNC coil winding machine
are ‘hot wound’ whilst the bar is still at over 950°C and the hardening and tempering of our coil springs is completed by an extremely precise electronically controlled furnace to eliminate breakage and
Wounded coil is now dipped with a phosphate coating for maximum corrosion protection. A durable epoxy powdercoat finish provides extreme protection against the elements.
