SRP140349 Srp Sbc 4.040″ Pistons + 7cc Dome 3.750″ St 6.000″ Rod 1.125″ Ch

Description

Achieve superior engine efficiency and power with SBC 4.040″ pistons, meticulously designed to optimize combustion and mechanical balance. These pistons address common engine limitations by providing precise dimensions that enhance fuel burn and reduce wear, resulting in increased performance and durability.

The 7 cc dome piston head increases the compression ratio, improving combustion efficiency and power output. This design reduces detonation risk, allowing for more aggressive tuning without compromising engine reliability. The 3.750″ stroke combined with the 6.000″ connecting rod length delivers an ideal rod-to-stroke ratio, minimizing side loading on cylinder walls and extending engine life.

Constructed by Srp, these pistons weigh 6.85 kg per set, balancing lightweight design with structural strength to withstand high RPMs and combustion pressures. The 1.125″ chamfer ensures smooth piston-to-cylinder wall clearance, reducing friction and promoting consistent operation under extreme conditions.

Measuring 73.00 cm in length, 30.00 cm in width, and 12.50 cm in height, this piston assembly fits standard small-block Chevy configurations, providing a direct replacement or upgrade option without extensive modifications. The precise engineering and dimensions maintain factory tolerances while delivering enhanced performance characteristics.

Ideal for engine builders focused on maximizing output and reliability, this piston set supports both street performance and racing applications. The combination of dome volume, rod length, and chamfer specifications creates an optimized combustion environment for improved throttle response and horsepower gains.

Upgrade your engine with SBC 4.040″ pistons that deliver targeted performance enhancements through exact engineering and material quality. These pistons provide a measurable increase in combustion efficiency and mechanical stability, ensuring your engine operates at peak capability under demanding conditions.
