Pro HD Valve Train Kit | Toyota 2TR-FE (20+ lbs Boost)

When your Toyota 2TR-FE is pushing 20+ lbs of boost, standard components simply cannot handle the extreme cylinder pressures and thermal loads. LC Engineering's Pro HD Valve Train Kit is the definitive solution for high-horsepower builds, drag racing, and professional competition. This kit replaces the entire top-end assembly with race-spec hardware designed to eliminate valve float, withstand immense heat, and support high-lift camshafts at 8,000 + RPM.

Oversized +1mm Performance Valves

This kit features +1mm oversized valves (32.50mm) to maximize flow in ported heads.

• Intake Valves: Manufactured from 21-4N high-grade stainless steel with a black Nitride anti-friction coating for superior airflow and guide longevity.
• Exhaust Valves: Crafted from Inconel, a high-nickel alloy designed for extreme heat resistance. These are 10% lighter than stock, allowing for more aggressive spark timing and improved valve-train stability under intense forced induction.

-Note: Requires a performance valve job. Bowl and chamber porting is highly recommended to fully utilize oversized valves.

Pro HD Dual Valve Springs & Seats

A "must-have" for high-boost applications to prevent the intake valves from being blown open by manifold pressure.

• Design: Dual-Spring configuration for superior harmonics and safety.
• Seat Pressure: 85 lbs @ 1.430" installed height.
• Performance: Rated for 20+ lbs of boost and high-lift cams (up to .527").
• Precision Seats: Included spring seats allow the dual-spring setup to drop in without cylinder head modifications.

Titanium Retainers & Viton Seals

• Titanium Retainers: American-made from space-age materials, these are less than half the weight of steel but ten times stronger. They drastically reduce reciprocating mass, providing total confidence when revving beyond 8,000 RPM.
• Viton Valve Seals: Rated for temperatures up to 440°F (226°C), these seals provide a superior oil barrier compared to OEM rubber, ensuring your intake stays clean and oil consumption remains minimal.

Technical Specifications

• Spring Rate: 11.70 lbs/mm
• Max Lift: 13.40mm (.527")
• Coil Bind: 22.20mm (.824")
• Open Pressure: 195 lbs @ .400"lift
