Pro HD 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. The kit contains our Pro HD Dual Valve Springs, Titanium Retainers, spring seats, and Viton valve seals.

Pro HD Dual Valve Springs

The Pro Dual Valve Springs are a "must-have" upgrade when running bigger lift cams and higher RPM's. With 71lbs of seat pressure and open pressure of 200lbs (at .400" lift) they will work perfectly with any high boost application (10-30lbs of boost). These springs are rated up to 10,000 RPM and will accommodate cam lifts up to .550"!

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 version of this kit for naturally aspirated or lower boost applications, see Part #: 1023215, or a Beehive spring kit for extreme boost applications 1023213.
