Description:
1. The drag springs showed are front drag coil springs which are closed and ground on one end to provide proper contact with the jack plate, not forged.and the opposite end is either open or closed tangential to fit properly into the lower control arm.
2. Our drag coils springs are made of the highest grade of Chrome Silicon wire 55CrSi which is close to SAE 9254.
3. For automotive springs including drag coil spring,we only choose the surfact treatment powder coating,not plating to protect the spring from hydrogen embrittlement, a corrosive break down of the spring’s surface which decreases the spring’s life.
4. Standardized testing procedures.
5. We adopt cold wound way to produce drag coil springs,each drag coil spring is properly heat treated and stress relieved to insure the sides of spring remain parallel during installation.
6. Custom winding is available upon request.
