Designed for high performance and durability in the crucible of competition. Whether you are racing at the National level or a weekend warrior, iK competition springs will help maximize the performance of you and your kart.
iK Competition springs are made in the USA - Aerospace Stainless & Military Spec
The Problem: Current Material and Design Most (all) current springs are manufactured from music wire (high carbon steel). Music wire has poor corrosion resistance, which can effect spring performance in adverse weather conditions. Many times, these springs are plated to improve corrosion resistance but often, the plating process engenders durability issues as they are not prepared properly for long-term use prior to plating. More importantly, music wire has a maximum service temperature of 250°F and can be negatively effected at temperatures as low as 185°F. As a spring nears its maximum service temperature, the heat promotes spring set, damage to the spring, and is detrimental to the relaxation of the spring. Additionally, the material used limits the design and angle of the spring hook radius, necessitating and ensuring a repeated fail point (visible at the bend where hook end meets coil) in most all traditionally designed, widely distributed kart springs.
The Solution: iK Competition Springs Each spring is manufactured from certified aerospace specification 17-7ph stainless alloy. After winding, the springs are fully heat-treated, stress relieved and passivated. Although our aerospace stainless needs no plating we do passivate our springs in order to decontaminate and cleanse the metal at a microscopic level post-winding combating the dehabilitating effects of winding on the metal. This step in our engineering process, combined with the high strength, corrosion resistance, and Rockwell of C50 inherent in 17-7ph stainless translates to our springs withstanding a maximum service temperature of 700°F. Because of the quality of our materials and process, our springs can be stretched for use up to double their resting length with no yield in recoil, offer consistent performance when heat becomes a factor, such as with header/exhaust springs and clutch springs, and are designed to minimize key fail points in current karting spring designs. Our full product line undergoes a 96-hour military stress test with no resulting corrosion, loss of strength, or durability.
Don't let a broken spring lose a race for you. Too many races are lost from broken exhaust springs causing pipes to fall off, or broken springs on side-pods allowing the pod to come off.
