Safely increase your powerband and rev higher by upgrading your valve springs and retainers, a must for anyone looking to rev out past 7500rpm. Performance valve springs feature higher spring rates reducing the chance of valve float and engine damage at higher RPM. Titanium retainers reduce mass allowing the valve train to rev higher, faster. The use of titanium provides an adequate fatigue life to be acceptable for all but the highest mileage street use. Supertech'sI spring kit is rated for use in engines up to 8300-8500rpm.
