Description

Brian Crower Single Valve Spring & Titanium Retainer Kit – Toyota 1JZ / 2JZ

Push Your JZ Engine to the Limit When chasing high horsepower and elevated RPM limits in your Toyota 1JZ or 2JZ engine, securing reliable valvetrain control is absolutely critical. The Brian Crower (BC0300) Single Spring and Titanium Retainer Kit is engineered specifically to prevent valve float and ensure precise timing in high-boost, high-RPM applications. Designed to comfortably handle up to 9,000 RPM and 800 WHP, this kit is an essential upgrade for any serious street or track build.

What Does “Single Spring” Actually Mean? Please Note: Brian Crower refers to this as a “Single Spring” kit, which describes the spring’s physical design (a single coil as opposed to a dual/inner-and-outer spring setup). Rest assured, this is a complete, engine-wide kit. Because the Toyota 1JZ and 2JZ are inline 6-cylinder, 24-valve engines, this package includes exactly what you need for a full cylinder head rebuild: 24 high-performance valve springs and 24 CNC-machined titanium retainers. Unrivalled Manufacturing Quality The BC1300 valve springs are wound exclusively by PAC Racing—the industry leaders in motorsport valvetrain components. They are constructed from the highest-grade, super-clean chrome silicone alloy and subjected to proprietary processing procedures. This ensures incredibly consistent seat pressures and long-term durability under extreme stress. Paired with BC’s ultra-lightweight titanium retainers, this kit reduces overall valvetrain mass, translating to faster engine response and reduced wear.

Key Features:

• Complete 48-Piece Set: Includes all 24 springs and 24 titanium retainers required for your 1JZ or 2JZ cylinder head.

• High-Performance Limits: Safely supports engine speeds up to 9,000 RPM and power outputs up to 800 WHP.

• Premium Materials: Springs wound by PAC Racing using aerospace-grade chrome silicone alloy.

• Reduced Mass: BC2300-24 titanium retainers significantly lower valvetrain weight for higher RPM stability.

• Drop-In Fitment: Designed to be used with your OEM spring seats.
