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 Beehive Spring!
Pro Beehive Valve Springs
The Pro Beehive Valve Springs are a "must-have" upgrade when running bigger lift cams and higher RPM's. With 120lbs of seat pressure and open pressure of 255lbs (at .400" lift) they will work perfectly with any extreme boost application (30lbs+ of boost). These springs are rated up to 10,000 RPM and will accommodate cam lifts up to .540"!
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.
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 lower spring pressure versions of this kit for naturally aspirated or lower boost applications, see Part #: 1023215 or 1023214.
