Product Details

The Wiseco K472X25 is a Professional Series forged piston set engineered for high-performance and racing builds based on the Chrysler 6.1L 3rd Generation Hemi platform. Featuring a -15.0cc dish crown and 8.7:1 compression ratio at stock stroke, this set is designed to deliver reliable power in street/strip and forced induction applications where a lower compression ratio is desired.

Wiseco's Professional Series pistons are manufactured in the USA from 2618 high-strength aluminum alloy, providing superior tensile strength and thermal fatigue resistance compared to standard 4032 alloy pistons. Each piston features Wiseco's proprietary ArmorGlide® skirt coating for reduced friction, seizure resistance, and quieter operation under demanding conditions.

Key Specifications:

  • Bore: 4.080 in. (+0.025 in. over stock)
  • Compression Height: 1.205 in.
  • Stroke: 3.580 in. (stock)
  • Rod Length: 6.243 in.
  • Crown Style: Dish (-15.0cc)
  • Wrist Pin Diameter: 0.927 in.
  • Advertised Weight: 456 grams
  • Material: 2618 high-strength forged aluminum

What's Included:

  • 8 forged pistons
  • 8 wrist pins
  • High-performance piston rings
  • Lock rings

Important Installation Note: The 0.927 in. wrist pin diameter requires the use of aftermarket connecting rods (such as matching K1 rods). These pistons are not compatible with OEM stock connecting rods. Builders should verify piston-to-valve clearance and confirm proper ring gap before installation.

Whether building a naturally aspirated 421+ cubic inch stroker combination or a boosted 6.1L Hemi, the Wiseco K472X25 provides the durability and precision machining needed for serious performance builds.

Found what I needed quickly, check out was simple. Received my order in one day.

Easy, clear, fast !!!! I only put one star for satisfaction because I won't know until the product is installed and I can check it for fit and form. I suspect it will be satisfactory since it replaces one I previously purchased. ..... however I wish it would last longer than the last one ...... approximately 4 years.

Loved your website...easy to maneuver and easy to checkout. Thanks!

Easy to use and cheap shipping.

I purchased "Carrand Whisk Broom 10'' W Label",after exhaustive research for this particular item...they have the BEST/LOWEST COST for this item anywhere!!<br><br>Shipped in a timely manner too!<br><br>Will do business here again in the future,as they have prices that are LOW,plus the great products are found here too.<br><br>Thanks to the staff for a great online shopping experience!
