Performance Springs Mitsubishi 6G72 Dual Valve Spring & Ti-Retainer Kit

<

Upgrade valve control and reliability in your Mitsubishi V6 build with the Dual Valve Spring & Titanium Retainer Kit for Mitsubishi 6G72 SOHC Engines. Designed for engines operating at higher RPM or under forced induction, this dual-spring setup delivers the increased spring force required to safely support higher lift camshafts and aggressive valve events.

The dual-spring geometry provides superior valve control compared to single-spring configurations, reducing the risk of valve float under high cycle rates. Paired with lightweight titanium retainers, this kit improves stability while minimising valvetrain mass—critical for performance-focused 6G72 applications.

Spring Characteristics

• Seat Pressure: 100 lbs
• Open Pressure: 225 lbs @ 0.400" (10.1 mm) lift

Key Features

• Dual valve spring configuration for improved high-RPM valve control
• Suitable for higher lift camshafts and forced-induction applications
• Titanium retainers reduce valvetrain mass and improve response
• Designed specifically for Mitsubishi 6G72 SOHC engine platforms
• Ideal for performance street, track, and boosted engine builds

Why Choose This Dual Valve Spring Kit?

As cam lift, RPM, and cylinder pressure increase, factory valve springs quickly reach their limits. This dual valve spring and titanium retainer kit is engineered to provide the extra control required to keep valves stable and seated under demanding conditions—protecting your engine and unlocking reliable performance.

Whether you're building a boosted street car, a track-focused setup, or a high-performance naturally aspirated 6G72, this kit delivers the spring pressure and durability needed for confident operation at elevated RPM.

Perfect for Mitsubishi 6G72 SOHC engines used in performance, turbocharged, and motorsport applications where precise valvetrain control is critical.
