Moose Racing High Compression Piston Kit

The Moose Racing High Compression Piston Kit line gives four-stroke powersports engines a forged, high-performance replacement piston. It suits riders who want more compression for racing or competitive off-road use. Each kit is built as a complete top-end piston package, so you can use it for a performance upgrade or a rebuild.

Key Features:

• Forged construction: X-style forgings aim for strength, durability, power, weight reduction and less friction. Some applications use fully boxed-style race forgings.
• Domed crown design: The slightly domed design maximizes squish and helps prevent hot spots that can cause detonation.
• Internal bracing: Internal bracing improves durability and reduces friction in the pin assembly.
• Skirt coating: Boxed-style forgings with a skirt coating dissipate heat well.
• DLC wrist pin: The DLC (diamond-like coating) piston pin reduces friction and resists wear, which extends service life and reliability.
• Made in the USA.

What's included: A high performance piston, wrist pin, rings and circlips.

Higher compression pistons can require race fuel in some applications. Check the manufacturer's application chart for the model you are building. Moose Racing is a well-known name in off-road and powersports parts, and these pistons carry that reputation into engine builds for motocross, off-road and ATV use.
