The JUN valve spring kit consists of both inner and outer springs. This kit is for the serious racer who plans on revving well past 9,000RPM. The special wound springs will not bind with even the highest lift camshafts. These valve springs are recommended for use with JUN Type-3 camshafts or any other very high lift camshafts. The complete JUN valve spring and titanium retainer kit is also available.
JUN Titanium Retainers are another good choice of retainers to be used for your B-series valvetrain. Ultra-lightweight, these retainers are one of the lightest on the market.
Please contact us to special order H-series valve springs or titanium retainers.
