Product Details

The Wiseco K0243A7 is a Professional Series forged piston kit engineered for high-performance Big Block Chevy 489 cubic inch builds (454 stroker). Featuring a 4.320" bore, 25cc closed-chamber dome crown, and a compact 1.270" compression height, this kit is precision-built to deliver a targeted 10.5:1 compression ratio when paired with a 118cc cylinder head and a 0.040" head gasket at zero deck. Sold as a complete 8-piston kit, the K0243A7 is purpose-built for serious street and drag strip applications demanding maximum power and reliability.

Each piston is forged and fully machined in Wiseco's Mentor, Ohio USA facility from 2618 high-strength aluminum alloy — the material of choice for forced induction and high-heat environments due to its superior tensile strength and thermal expansion properties.

Key Features:

  • Bore: 4.320"
  • Compression Height: 1.270"
  • Crown Volume: 25.0cc dome
  • Stroke: 4.250"
  • Rod Length: 6.385"
  • Pin Diameter: 0.990"
  • Piston Weight: 630g each
  • Ring Lands: 1/16", 1/16", 3/16" (rings sold separately)
  • ArmorGlide® skirt coating for seizure resistance, friction reduction, and quieter operation
  • Anti-detonation and pressure seal grooves for improved ring seal
  • 2618 forged aluminum alloy construction for heavy- to severe-duty performance
  • Forged, engineered, and machined in the USA

Note: Rings are sold separately. This is a build-to-stock (B) item. The K0243 series does not include vertical gas ports.

Great price - fast shipping ! Will definitely use boatplicity again!

Web site was fast and pricing was excellent

I found the site easy to use and with the tires hard to find tires I needed at a great price. Quick response, shipping, delivery. Could not ask for more.

Will order again. Thank you!

Called Customer service to verify fitment of a radiator, due to the convoluted path that Google took me on to find it, here. The lady was quick to get me the answers I needed, and very courteous. The price was great. I had the radiator in my cart before we were even off of the phone. Here's to hoping that her information was correct.

Easy and quick to use love it.
