Product Details

The Wiseco K420B125 is a shelf-stock forged piston set designed for Big Block Chevrolet (BBC) applications. Built from high-strength forged aluminum, these pistons deliver superior durability and thermal management compared to cast alternatives, making them an excellent choice for performance street and racing builds.

Key Features:

  • Bore Size: 3.815" standard shelf-stock sizing
  • Construction: Aircraft-quality forged aluminum alloy for maximum strength and reduced weight
  • Oversize: +0.125" over standard bore for use in freshly bored or rebuilt Big Block Chevy engines
  • Ring Grooves: Precision-machined ring lands for optimal ring seal and longevity
  • Wrist Pin: Includes Wiseco high-strength wrist pins for a complete, ready-to-install set
  • Shelf Stock: Ready to ship without custom lead times

Wiseco's forged pistons are manufactured in the USA and are engineered to withstand the demands of high-compression, forced induction, and nitrous oxide applications. The K420B125 piston set is a direct-fit solution for Big Block Chevy engines that have been bored 0.125" over standard, providing a reliable foundation for any serious engine build.

Good price great quality

Fast service and shipping, Plus the lowest price for the high performance k&n air filter<br>I wanted.

I was hesitant to order from Autoplicity due to the perception that the price was too good to be real (and not some scam). However, I read a few reviews on the internet and decided to take a chance. Once I placed my order I was sent a tracking number and received my car parts within 2 weeks. I was happy that I got the parts I ordered and the price was really low. Simple and quick.

Great prices.
