SRP140674 Srp Sbc 4.030″ Pistons +11cc Dome 3.480″ St 5.700″ Rod 1.560″ Ch

Description

Enhance your engine’s power and efficiency through precision-engineered pistons that improve combustion dynamics and durability. The SBC 4.030″ pistons with a +11 cc dome increase combustion chamber volume, directly improving compression and power output for high-performance applications.

These pistons feature a 3.480″ stroke and a 5.700″ rod length, designed to maintain optimal piston travel and stability within the cylinder, reducing wear and ensuring consistent power delivery. The 1.560″ compression height is calibrated for precise engine geometry compatibility, minimizing the risk of mechanical interference.

Manufactured by Srp, these pistons weigh 6.85 kg, balancing strength with weight to reduce reciprocating mass and enhance engine responsiveness. Their dimensions—73.00 cm in length, 30.00 cm in width, and 12.50 cm in height—reflect the complete assembly size, ensuring straightforward integration into SBC engine builds.

Constructed from high-grade materials, the pistons are designed to withstand high combustion pressures and temperatures, making them suitable for both street and performance racing engines. The +11 cc dome shape also supports efficient air-fuel mixture compression, directly benefiting throttle response and fuel economy.

Compatibility with standard SBC engine components is assured through the 4.030″ bore diameter, maintaining precise sealing and minimal blow-by. The design’s focus on dimensional accuracy and performance consistency reduces maintenance intervals and enhances engine longevity.

Incorporating these pistons into your engine rebuild or upgrade delivers measurable improvements in power and reliability, supported by Srp’s commitment to exacting manufacturing standards. This product is engineered to meet the demands of serious builders seeking dependable performance gains without compromising engine integrity.
