SRP138094 Srp Sbc 4.040″ Pistons 5cc Flat 3.750″ St 6.000″ Rod 1.125″ Ch

Description

Maximize engine efficiency and power with SBC 4.040″ pistons designed to deliver precise combustion control through their -5 cc flat top configuration. This design reduces detonation risk and improves fuel burn, making it ideal for performance engine builds demanding reliability and consistency.

The pistons feature a 3.750″ stroke and a 6.000″ connecting rod length, engineered to maintain optimal piston speed and reduce friction for enhanced durability under high-stress conditions. A 1.125″ compression height ensures proper piston-to-cylinder head clearance, critical for maintaining consistent compression ratios and avoiding mechanical interference.

Manufactured by Srp, these pistons weigh 5.75 kg collectively, balancing strength and weight to minimize reciprocating mass while sustaining structural integrity. Their dimensions—33.00 cm in length and width, and 18.00 cm in height—reflect compact design considerations suitable for SBC engine blocks requiring precise component fitting.

Constructed from high-grade materials tailored for thermal resistance and wear durability, these pistons support extended engine life even under rigorous conditions. The flat top design with the -5 cc volume adjusts the combustion chamber size, allowing tuners to optimize compression ratios for specific fuel types and power goals.

Engine builders seeking to improve throttle response, increase horsepower, and maintain engine longevity will benefit from these pistons’ exacting specifications. The precise rod length and stroke combination ensures compatibility with standard SBC blocks while enabling performance upgrades without compromising engine balance.

Invest in pistons that deliver consistent performance and reliability through exact engineering tailored to small-block Chevrolet engines. This set supports your goal of achieving superior combustion efficiency, reduced engine knock, and increased overall power output with confidence and precision.
