All front springs are closed and ground on one end to provide proper contact with the jack plate, not forged. The opposite end is either open or closed tangential to fit properly into the lower control arm.
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.
Each spring is designed with the correct pitch and height ratio to insure consistent rate throughout the entire cycle.
Custom winding is available upon request.
