- All rear springs are closed and ground on both ends which insures proper contact with the jack plate and spring seat.
- Made of the highest grade of Chrome Silicon wire found worldwide.
- Cold wound, not hot wound. Each coil-over spring is properly heat treated and stress relieved to insure the sides of spring remain parallel during installation.
- Standardized testing procedures.
- Powder-coated, not plated to protect the spring from hydrogen embrittlement, a corrosive break down of the spring’s surface which decreases the spring’s life.
