Superior Premium Coil Springs THE BEST THERE IS Posted By: Superior Engineering Published: 03/12/2015
Times Read: 5842 Comments: 0 Superior Engineering Heavy Duty Coils are manufactured from the highest quality materials available providing better load carrying capacity, enhanced road handling and a longer life. This technologically advanced material allows us to create some of the smoothest riding coils in the world!
STATE OF THE ART HEAT TREATMENT
Heat treatment is the most important step in the coil spring manufacturing process. Hardening and tempering is completed by an extremely precise, electronically controlled furnace to eliminate breakage and sagging.
FORMED ON PRECISION MANDRELS
During forming, each coil is precisely placed, wound and monitored by a programmable hi-tech computer to achieve perfect pitch. This is especially important in manufacturing our heavy duty springs to the exact spring rates.
PRECISE END CONFIGURATIONS
Our precisely engineered coil ends are designed to fit directly into the original vehicles mounting points without modifications.
POWDER COAT FINISH
A durable black powdercoat finish is baked on, to provide extreme protection against the elements and to help eliminate corrosion. The smooth powdercoat surface also reduces friction when used with internal airbags.
HIGH INTENSITY SHOT PEENING
All Superior coils are shot peened to give longer life, reducing micro cracks and increasing the springs toughness.
FULLY SCRAGGED & LOAD TESTED
All Superior coils are scragged 100% to eliminate subsequent spring sag. The coils are also load tested to ensure they meet and maintain the required specifications. Superior also performs spring fatigue testing and spring hardness testing using state of the art testing equipment.
