Product Details

The Wiseco 4794M08900 is a high-performance forged piston kit designed specifically for popular sport ATVs. This oversized piston features an 89mm bore diameter (4.5mm over standard 19.5mm compression height) and is engineered to deliver exceptional durability and performance in demanding riding conditions.

Key Features:

  • 100% forged in-house construction for superior strength and impact resistance
  • Condensed grain structure aligned to part features for maximum durability
  • Optimized strength-to-weight ratio for enhanced performance
  • Advanced skirt coating for reduced friction and longer wear
  • Designed to withstand extreme racing and high-performance applications
  • 89mm bore diameter (4.5mm oversized for cylinder boring applications)

Fits:

  • Arctic Cat DVX 400 2x4 (2004)
  • Kawasaki KFX400 (2003-2006)
  • Suzuki LTZ400 Quadsport (2002-2009)

Wiseco pistons are manufactured entirely in the USA with complete control over every aspect of the forging process, from raw material to finished product. Unlike brittle cast pistons that can fail catastrophically under stress, Wiseco's forged pistons provide the toughness and reliability required for high-performance motorsport applications.

They had exactly what l needed.

I'm a first time customer. So far so good. If I should get these two chairs this week i'll be ecstatic!!!!!

Great prices! Had exactly what I was looking for, for $20 less than anywhere else even with the shipping cost added in.

Quick and easy.

Compared to other auto parts sites (Summit, JEGS, etc.) not only was shipping to Hawaii half the cost, but the product itself was cheaper too!

I love to shop at Autoplicity because of their selections and pricing options. Fast shipping and great customer service. The only thing I'd like to see is the site needs a continue shopping option after looking at cart. My overall experience has always

Lowest price I could find. Cheap shipping for the size. Pretty happy

Easy checkout with Amazon
