SRP140690 Srp Sbf 4.040″ Pistons 5cc Flat 3.400″ St 5.400″ Rod 1.100″ Ch

Description

Enhance your engine’s power and reliability with pistons designed to deliver precise combustion control and durability. These Srp pistons feature a 4.040″ bore diameter combined with a -5 cc flat top design that reduces combustion chamber volume, increasing compression efficiency and optimizing power output.

The 3.400″ stroke and 5.400″ connecting rod length are engineered to maintain ideal piston travel and reduce side loading within the cylinder bore, which minimizes wear and enhances engine longevity. A 1.100″ compression height ensures compatibility with standard short-block assemblies, facilitating straightforward installation and maintaining factory tolerances.

Each piston weighs 5.6 kg, reflecting a robust construction suitable for high-performance applications while balancing mass for efficient engine responsiveness. The dimensions—33 cm in length and width, and 18 cm in height—support precise fitment within Small Block Ford (SBF) configurations, ensuring consistent operation under high RPM conditions.

Manufactured by Srp, a brand known for strict quality control and material integrity, these pistons provide exceptional resistance to thermal and mechanical stress. Their flat top profile is specifically designed to accommodate a -5 cc volume reduction, which enhances the compression ratio without requiring extensive modifications to the cylinder head or gasket thickness.

This combination of specifications not only improves horsepower and torque but also optimizes fuel efficiency by promoting more complete combustion. The 4.040″ bore size is ideal for SBF engines aiming to upgrade displacement and performance without compromising reliability.

The pistons’ precise engineering and material selection make them suitable for performance rebuilds and high-output street or track engines, where durability and consistent power delivery are critical. The 1.100″ compression height aligns with many aftermarket and OEM components, reducing compatibility issues during engine assembly.

In summary, these Srp SBF pistons offer a targeted solution for engine builders seeking to increase compression and performance with proven dimensions and material robustness. Their design promotes efficient combustion, engine longevity, and reliable power gains, making them a strategic upgrade for serious engine enhancement projects.
