Show original supplier description

The Kibblewhite 30-30320 is a high-performance, lightweight racing valve spring kit engineered for demanding motorsport applications. Kibblewhite Precision Machining has leveraged years of experience to create these robust valvetrain components, starting with premium chrome-silicon wire wound to precise standards. This kit includes dual springs per valve, constructed with titanium retainers and steel locks for a balance of strength and weight savings. The springs provide a seat pressure of 63 lbs. at their installed height and accommodate a maximum lift of 0.460 inches for both intake and exhaust valves, ensuring reliable operation under high-revving conditions. These valve springs are ideal for high-revving motors in racing or trail riding scenarios, offering an upgrade over stock components to prevent potential failures. This Kibblewhite valve spring kit is specifically designed for the 1968-1973 Honda CB350K Super Sport and CL350 Scrambler models.
