Product Details

The Icon Pistons IC851.STD forged piston set is engineered for high-performance Chevy 434 cubic inch builds utilizing a 6.000-inch connecting rod length. These pistons feature a stepped dish design that optimizes combustion chamber geometry for improved power delivery and efficiency.

Key Features:

  • Forged construction for superior strength and durability under high cylinder pressures
  • Designed specifically for 434 cubic inch Chevrolet engines
  • Compatible with 6.000-inch connecting rods
  • Stepped dish design for optimized compression ratio
  • Precision-machined ring grooves for proper seal and reduced blow-by
  • Advanced alloy composition resists thermal expansion and detonation

Icon forged pistons are manufactured to exacting tolerances and provide the strength needed for street performance and racing applications. The stepped dish configuration allows engine builders to fine-tune compression ratios while maintaining proper quench heights for detonation resistance.

Good store to deal with.<br><br>Will purchase from them again.

I was very surprised that even with shipping, I saved 40% over the exact same item at a local auto store. They shipped the next business day and I am expecting to receive within 1 week of placing the order.<br>Autoplicity's website is easy to navigate and the selection and prices are top notch. I will be ordering from here again!
