Description:
1. These rear coils are desgined to lower your truck, while still maintaining a proper spring rate to keep your suspension from bottoming out.
2. Our pigtail coils springs are made of the highest grade of Chrome Silicon wire 55CrSi which is close to SAE 9254.
3. We adopt cold wound way to produce pigtail coil springs,each pigtail coil spring is properly heat treated and stress relieved to insure the sides of spring remain parallel during installation.
4. For automotive springs including pigtail 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.
5. Standardized testing procedures.
6. Custom winding is available upon request.
