Series delivers this level of full throttle, indefatigable performance. The Anatomy of a World Class Valve Spring.
Superclean High-Alloy Wire A world class valve spring begins with the finest valve spring wire. Gold Stripe Springs are precision-wound from custom drawn, vacuum de-gassed "super-clean" high alloy spring steel.
Superfinishing and triple ultrasonic inspection assures a seamless, defect-free smooth surface. Laboratory tests confirm, no finer valve spring wire has ever been produced.
Precision Winding; Accurate Pitch Control Compress a Tool Room. Gold Stripe Spring to the full valve open position. Notice how evenly the coils close down from one side to the other, allowing for more uniform load & stress distribution. That's what precision winding is all about! Absolute Concentric Diameters Have you ever noticed that the end coils of some valve springs are not concentric (on the same center) as the middle coils of the spring?Because they are wound so concentrically, Tool Room. Gold Stripe Springs maintain a consistent, precise interference-fit and optimum dampening between thir outer and inner components. Ends Precision Ground, Flat & Parallel Slow, precision feed rates no forced grinding on Tool Room.
Gold Stripe Springs produce exceptionally flat, smooth end surfaces. Superfinishing eliminates burrs and retainer chafing.
Body to end squareness is exceptionally accurate and Tool Room. Gold Stripe Springs maintain their squareness under load, eliminating unwanted bending stresses for longer valve spring, guide and seat life! Surface Conditionning "State of the Art", 100% full coverage uniform shot-peening guarantees never an over or under-peened surface, significantly improving fatigue life in Tool Room. Subsequent proprietary conditioning operations "burnish" the surface of Tool Room. Spring to reduce unnecessary friction, lower operating temperatures and eliminate the need for expensive coatings!
Near-Zero Load Loss Processing Exceptional endurance properties are the essence of the Tool Room. While other valve springs may experience an initial 15-30 lb. Drop almost immediately, Tool Room. Springs typically lose less than 5 lbs. After 1,000 Racing Test Miles!
Sorry, it really is a trade secret. But, we can tell you that we employ a special high-temperature load-retention process that is unique in the high performance industry!
Digital Load-Testing Spring loads and rates are closely monitored throughout the manufacturing and assembly process by highly accurate computer controlled load cell/test stations, which are calibrated twice daily. Lab Certified, Micro-Refined Grain Structure Special low temperature processing techniques produce a micro-refined material grain structure verified by routine scanning electron microscopy.
Improved ductility and a dramatic extension in valve spring fatigue life results from these procedures, exclusively applied to Tool Room. Every part number, every batch. Our competition merely gives the illusion of endurance testing. Five or ten minutes of "Phantom Testing" at RPM may ease their conscience but it does nothing for their customers' "peace of mind". At Isky, we subject Tool Room.
Springs to the most rigorous real world endurance test ever established. The gruelling 1,000 Racing Mile Spintron® Endurance Test Standard. THIS IS IN GOOD CONDITION.
