CP Piston Bullet Race Series Holden -12CC Holden Heads 4.030 Bore 3.480 Stroke 5.700 Rod Set Of 8

CP Pistons Bullet Race Series forged pistons are built for Holden heads, specifically designed for a 4.030 inch bore with a 3.480 inch stroke and a 5.700 inch rod. This set of eight pistons is intended for performance-oriented Holden engine builds where strength and reliability under demanding conditions are critical. The -12cc dish volume is a key feature, influencing your engine's compression ratio when paired with specific cylinder heads, allowing for precise tuning of power output and combustion characteristics. These pistons are constructed from well-built forged aluminum, a material chosen for its superior strength-to-weight ratio compared to cast aluminum, making them resistant to the high pressures and temperatures found in performance engines. This construction helps prevent piston failure, such as cracking or deformation, under extreme load.

The Bullet Race Series is engineered for those pushing the limits of their Holden engines. The forged process creates a denser, more uniform grain structure in the aluminum, which significantly enhances durability and resistance to detonation. Each piston in this set is precision-machined to exacting tolerances, ensuring a consistent fit and performance across all cylinders. This attention to detail is crucial for achieving optimal engine balance and power delivery. While these pistons are built for high performance, it's important to note they are not CARB approved and cannot be shipped to California. Proper installation and matching with compatible components like rings, connecting rods, and cylinder heads are essential for realizing their full potential and ensuring engine longevity.
