SRP139831 Srp Bbc 4.280″ Pistons +43cc Dome 4.250″ St 6.385″ Rod 1.270″ Ch

Description

Optimize your engine’s power output and reliability with SRP’s BBC 4.280″ Pistons designed specifically for high-performance applications. The +43 cc dome volume enhances combustion chamber efficiency, increasing compression for improved horsepower and torque delivery.

These pistons feature a 4.280″ bore diameter, ensuring precise fitment for big block Chevrolet engines. This exact sizing minimizes piston-to-cylinder wall clearance, reducing unwanted friction and wear for extended engine life.

Constructed with high-grade materials, the pistons balance strength and weight, weighing just 7.7 kg for the set. This controlled weight decreases reciprocating mass, allowing the engine to rev faster and respond more quickly under load.

The 6.385″ connecting rods paired with a 1.270″ compression height ensure optimal piston travel and stroke ratio, contributing to efficient combustion and power transfer. The 4.250″ skirt design provides stability within the cylinder, reducing piston slap and noise during operation.

With overall dimensions of 73 cm in length, 30 cm in width, and 12.5 cm in height, these pistons fit seamlessly into standard big block engine assemblies while providing the performance enhancements demanded by serious builders and racers.

This specific piston design addresses common engine challenges such as heat dissipation, durability under high RPM, and maintaining tight tolerances. Its dome shape not only increases compression but also optimizes air-fuel mixture combustion, translating into smoother power delivery and improved fuel efficiency.

Choose SRP’s BBC 4.280″ Pistons for a measurable upgrade in engine responsiveness and longevity. Engineered with exacting standards and tailored dimensions, these pistons provide a performance edge that stands up to rigorous operating conditions.
