Item Description

ISKY DUAL VALVE SPRINGS 545 LB/IN 1.240" BIND HEIGHT 1.625" OD .770 ID ISK9955
Racers, prepare your engines to run harder, rev higher, and live longer with Isky Racing Tool Room gold stripe racing valve springs. For 9:1 and all-out high-compression oval track engines, you need the racing valve springs with gold stripes. Why? They're the mark of full throttle performance and unsurpassed excellence! Tool Room gold stripe springs are manufactured in the USA by master craftsmen employing the precision winding of premium "super-clean" high-alloy steel. Then, they're super-finished to ensure a seamless and burr-free surface with accurate pitch control and absolute concentric diameters. They utilize state-of-the-art surface conditioning and their trade-secret, high-temperature load retention process to create racing valve springs that you can count on for maximum endurance. Tool Room racing valve springs are put through a rigorous endurance test under actual engine/race track operating conditions where only the strong survive and win their stripes--gold stripes! When you're ready to go for the gold, go with the most durable and fatigue-resistant racing valve springs available--Isky Tool Room gold stripes.Specs:
