KIBBLEWHITE - 20-23500 - Racing Valve Spring Kit - '02-'22 Harley-Davidson and Buell Dyna 35th Anniversary Super Glide, Electra Glide Ultra Classic Low
Kibblewhite engineers this Racing Valve Spring Kit for '02-'22 Harley-Davidson and Buell engines around the specific demands of each application, factoring in cam profiles, harmonics, natural spring frequency, valvetrain mass, required pressure, wire stress, fatigue life, and engine rpm rather than using a one-size-fits-all spring rate. The springs are progressively wound from Kobe super-clean chromium silicon wire that's heat treated and shot peened for fatigue resistance, and the kit comes complete for one engine. Made in the USA.
