High Performance Pro Valve Train Kit 2RZ/3RZ

Pro Valve Train Kit

(High Performance)

LC Engineering has taken the guesswork out of your 2RZ/3RZ top end by offering this ready to install kit. These kits will supply you with all the compatible parts to upgrade the valve train on your performance engine. This kit is a perfect upgrade for use with stock cams or our Stage 1 cams.

Intake & Exhaust Valves

These stock sized stainless steel valves are lighter than stock parts. They’re also given a special anti-friction coating to promote better airflow and minimize resistance in the valve guide.

Street Valve Springs

The springs we’ve included in this kit offer a higher spring pressure, allowing your engine to reach higher RPM’s by reducing valve float. These valve springs are an excellent choice for a mildly built engine (naturally aspirated or low boost 0-10lbs). The springs specs are approximately 53lbs of seat pressure at 1.44" install height and about 145lbs at .450" lift. with coil bind occurring at .550" from the installed height.

Hardened Keepers

Hardened valve keepers fit all 6mm valves while using stock Toyota retainers or our Titanium Retainers. A must-have for high rpm applications!

Viton Valve Seals

Viton valve seals are the latest technology in valve seal material, providing heat resistance to 440 degrees Fahrenheit (266 C). While reducing oil consumption through the valve guide, these seals provide smoother engine idling by stopping manifold air, and oil leakage past the seal resulting in longer engine life.

NOTE: You will reuse your stock Toyota retainer and spring seat with this kit since there are no upgrade benefits over the stock parts.
