Pro Dual Valve Spring & Retainer Kit

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.

Pro Dual Valve Springs

The 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 Retainers

These 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.

Spring Seats

Our spring seats are custom designed to allow you to run our dual springs without having to machine the cylinder head or guides (like some of our competitor's kits require). You place this spring seat on top of your stock spring seat, and you are ready to go.

Viton Valve Seals

Why go to all the work of changing out your springs and not change the seals while they are sitting there in the open? LC Engineering uses only Viton seals which are proven to seal better and longer than any other material on the market.

NOTE: We also offer a higher spring pressure version of this kit for high boost applications, see Part #: 1023214, or a Beehive spring kit for extreme boost applications 1023213.
