Product Details

The Sealed Power H345DCP20 is a high-performance hypereutectic piston set designed for Small Block Chevy 350 engines with a 4.020" bore diameter. This complete engine piston set incorporates advanced manufacturing technologies to deliver exceptional durability, performance, and reliability for both street and performance applications.

Digital Diamond Profile (DDP) Technology:

  • Precision skirt profiles created through digitally-actuated diamond turning process
  • Barrel profile design promotes oil wedge formation between skirt and cylinder wall
  • Reduces friction and wear while improving piston stability

Thermal Arching Compensation (TAC) Ring Groove Geometry:

  • Ring grooves machined with precise uptilt angle to offset thermal distortion
  • Maintains square ring face-to-cylinder contact under operating temperatures
  • Increases combustion sealing for improved power output
  • Decreases oil consumption for cleaner operation

Duroshield Skirt Coating:

  • Next-generation friction-reducing coating applied to piston skirts
  • Reduces friction across entire RPM range for improved efficiency
  • Enhanced wear resistance for extended service life
  • Superior noise, vibration, and harshness (NVH) reduction

Precision Engineering:

  • Precision-machined pin bores accommodate both fixed and floating wrist pin installations
  • Weight-matched piston and pin assemblies within 4 grams (±2 gram maximum variation)
  • Ensures balanced engine operation and reduced vibration

This piston set represents Speed Pro's commitment to advanced engine technology, combining precision manufacturing with performance-enhancing features for reliable engine builds and rebuilds.
