Pro HD Valve Train Kit

(20+ LBS Boost)

LC Engineering has taken the guesswork out of your 2TR valve train. This valve train kit will supply you with all the compatible parts to upgrade your performance engine. The "Pro HD" kit includes our stainless steel Intake valves (+1MM), inconel exhaust valves (+1MM), Pro HD dual valve springs, spring seats, titanium retainers and Viton valve seals.

Intake & Exhaust Valves

These stainless steel valves are given a special anti-friction coating to promote better airflow and minimize resistance in the valve guide. High performance (21-4N) high-grade steel with a Black Nitride coating for less friction and longer life. These valves are 1MM larger than stock (stock valves are 31.50MM), which are great for ported street heads. Inconel valves are lighter than the stock steel valves and are extremely heat resistant. They are also manufactured with a special high nickel-based alloy that goes through a unique heat-treatment process, which yields extreme heat resistance, and enormous tensile strength properties resulting in better valve-train stability. A cooler valve improves the material strength and durability while allowing the tuner more flexibility and a wider range of spark timing advances. Combine that with an average weight reduction of 10% and there isn’t a cooler valve on the market! These valves will work with the stock seats once a performance valve job has been performed. It is highly recommended to un-shroud the valve with a bowl and chamber port work when using oversized valves.

Pro HD Dual Valve Springs

The Pro HD Dual Valve Springs are a "must-have" upgrade when running bigger lift cams and higher RPM's. With 85lbs of seat pressure at a 1.430" install height, they will work perfectly with any high boost application (20+lbs of boost).

• Type: Dual Spring
• Press.Seat: 85 @ 36.19mm (1.430")
• Open Press.Seat: 195 @ 10.16mm (.400")
• Max Lift: 13.40 (.527")
• Coil Bind: 22.20mm (.824")
• Rate: 11.70 lbs/mm

Spring Seats

These spring seats will sit on top of your stock spring seat and allow you to run our dual valve springs without having to modify your head.

Titanium Retainers

LC Engineering Titanium retainers are lighter and stronger than steel. Additionally, our Titanium design gives you confidence; no longer will you be worried about splitting a retainer and tearing up an engine when turning over 8,000 RPM. Titanium retainers are American made from space age material. Titanium is less than half the weight and ten times stronger than the factory steel retainer; these Titanium retainers allow you to use high lift cams without the chance of failure. From a standing idle to the most extreme rpm, our Titanium retainers perform flawlessly, without compromise.

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 a better oil seal and are longer lasting than stock.
