Landrum 18" x 5" O.D. Rear Coil Springs

All rear springs are closed and ground on both ends which insures proper contact with the jack plate and spring seat. Each coil-over spring is properly heat treated and stress relieved to insure the sides of spring remain parallel during installation. 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.
