(Includes: Stock Sized Stainless Steel Valves, Dual Valve Springs, Titanium Retainers, Hardened Keepers 31mm Buckets, & Viton Valve Seals)
LC Engineering has taken the guess work out of your 5VZ valve train. These valve train kits will supply you with all the compatible parts to upgrade the valve train on your performance engine. The Pro 5VZ kit includes our stainless steel(stock size 34mm intake and 27.5mm exhaust) valves, Dual valve springs, Titanium retainers, hardened keepers 31mm Buckets and Viton valve seals
This kit will require valve shims there is no way to tell which ones until all head work is accomplished and measurements taken with the head torqued down on the engine block and cams pre installed. Call Tech with questions.
Intake & Exhaust Valves
These swirl-polished valves have all of the performance features of our oversize valves, but don't require the bowl and chamber work to unshroud the valves. These stainless steel valves are lighter than the stock steel valves, and have a special anti-friction coating to promote better airflow across the valve as well as reduced resistance in the guide, resulting in better valve train stability.
Valve size is 34mm intake and 27.5mm exhaust.
Dual Valve Springs
The Pro Dual Valve Springs are a "must have" upgrade when running bigger
lift cams and higher RPM's. With 75lbs of seat pressure at 1.400" install height and open
pressure of 215lbs (at .450" lift) they will work perfectly with any
naturally aspirated or low boost application (0-20 lbs of boost). These
springs are rated up to 8,000 RPM and will accommodate cam lifts up to
.455". Coil Bind on these springs is at .500" from Install height.
Titanium retainers work perfect for any performance build. They are made of titanium with a dual step to give you superior strength without breaking the bank.
Hardened Valve Keepers fit all 6mm valves using stock Toyota retainers and our Pro Titanium Retainers. A must for high rpm applications!
These 31mm Cam Followers are designed for use with larger
profile cams in your 5VZ engine. The larger outside diameter
allows the cam profile to be much larger without the cam lobe rolling
off the edge of the Cam Followers. They will use our 8mm Pro
Shims and fit directly into your stock head with no modifications.
SHIMS NOT INCLUDED and we don,t what size you need until engine is assembled.
Viton Valve Seals
Viton Valve Seals are the latest in valve seal material, surpassing Teflon! Heat resistant to 440 degrees, they eliminate oil consumption through the valve guide and provide smoother engine idling by stopping manifold air and oil leakage past the seal. They insure a perfect seal for maximum performance and long engine life.
