LC Engineering has taken the guesswork out of choosing the right parts for your cylinder head! We have created a spring & retainer kit that comes with all the parts needed to upgrade your 1GR cylinder head to a dual spring set-up. The kit contains our Pro Dual Valve Springs, Titanium Retainers, spring seats and Viton valve seals.
Pro Dual Valve SpringsThe Pro Dual Valve Springs are a "must have" upgrade when running bigger lift cams and higher RPM's. With 61lbs of seat pressure and open pressure of 173lbs (at .390" lift) they will work perfectly with any performance application. These springs are rated up to 8,000 RPM and will accommodate cam lifts up to .590"!
Titanium RetainersThese lightweight retainers allow the valves to open and close faster and more consistent by reducing the drag and load on the springs. The titanium also provides superior strength and durability which means your engine can rev faster and higher than ever with no reliability worries.
Note:We also offer a higher spring pressure version of this kit for high boost applications (part #1023214) Or a Beehive spring kit for extreme boost applications (part #1023213).
