SRP311079 Srp Holden 355 4.020″ 12cc Dish 5.627″ Rod, 1.500″ Ch, D Bowl

Description

Maximize your engine’s power output and durability with pistons engineered to optimize combustion dynamics. The HOLDEN 355 4.020″ -12 cc DISH pistons address performance loss caused by inefficient piston design, ensuring consistent power delivery and reduced wear.

The 4.020″ bore diameter is precisely measured to ensure an exact fit within the cylinder, minimizing blow-by and improving compression. This tight tolerance translates directly into increased engine efficiency and smoother operation under high loads.

• -12 cc Dish Design: The -12 cc piston dish volume enables fine-tuning of the engine’s compression ratio, allowing for optimized combustion characteristics tailored to performance requirements.
• 5.627″ Rod Length: This connecting rod length balances piston speed and stroke, reducing side loading and friction, which extends engine component life and improves throttle response.
• 1.500″ Compression Height: Ensures proper piston positioning relative to the crankshaft, critical for maintaining correct valve clearance and timing, which enhances overall engine reliability.
• D-Bowl Crown: The D-bowl piston crown shape promotes efficient air-fuel mixture swirl, improving combustion efficiency and reducing emissions.
• Material and Weight: Weighing 6.1 kg, these pistons are constructed from durable materials engineered to withstand high thermal and mechanical stresses inherent in performance Holden 355 engines.
• Dimensions: With overall packaging dimensions of 33.00 cm (length and width) and 18.00 cm height, these pistons fit seamlessly into standard engine assemblies without requiring modification.

Designed by SRP, a trusted brand in engine components, these pistons provide a direct replacement solution engineered to exacting standards. Their precise specifications enhance engine responsiveness, reduce mechanical losses, and support higher RPM operation without sacrificing reliability.

When installing these pistons, expect improved combustion efficiency and extended engine life, backed by tight manufacturing tolerances and advanced piston crown geometry. This component is a strategic upgrade for performance Holden 355 engines seeking to maintain competitive power outputs with proven durability.
