Pro HD Dual Valve Spring & Retainer Kit - 2RZ/3RZ
Includes: Dual Valve Springs, Spring Seats, Titanium Retainers, Hardened Keepers & Viton Valve Seals
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 2RZ or 3RZ cylinder head to a dual spring set-up. The kit contains our Pro HD Dual Valve Springs, Titanium Retainers, Spring Seats, Hardened Keepers & Viton Valve Seals. This kit will work with the stock cam buckets or our shim in style buckets.
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 100lbs of seat pressure at a 1.400" install height and open pressure of 225lbs (at .450" lift) they will work perfectly with any high boost application (20+ lbs of boost). These springs are rated up to 10,000 RPM and will accommodate cam lifts up to .515"!
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 competitors kits require). You simply place this spring seat on top of your stock spring seat and you are ready to go.
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.
These keepers are specifically designed to work with our titanium retainer, that means you aren't getting some universal keeper that is made to fit who knows how many different applications. The keepers are also hardened to give you the strongest and longest lasting parts available.
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.
We also offer a lower spring pressure version of this kit for naturally aspirated or lower boost applications (part #1023222)
