Description

Predator 70mm Flat Top Piston Assembly Kit


The Predator 70mm Flat Top Piston Assembly Kit is a performance-focused replacement for stock Predator 212 pistons, offering increased strength, efficiency, and compatibility with a wide range of clone engines.


Engineered to OEM specifications, this flat top piston provides improved compression over the standard dished piston—ideal for performance builds where maximizing combustion efficiency and tuning potential is a priority.


This piston is most commonly used in stock bore 212cc Predator engines, as well as other small engine platforms that use a 70mm bore and 18mm compression height.


Piston Kit Includes:

  • 70mm Flat Top Piston
  • Piston Rings
  • 18mm Wrist Pin
  • Wrist Pin Clips


Key Specifications:

Compatibility

Predator 212, Hemi/Non-Hemi, and most 212cc clone engines with 70mm bore

Material

Cast aluminum (OEM-grade quality)


Benefits:

  • Flat top design improves compression and power potential
  • Direct fit for stock bore Predator 212 engines
  • Includes all necessary components for piston replacement
  • Compatible with most stock and performance connecting rods with 18mm wrist pins
  • Cost-effective upgrade for budget performance builds


Important Notes:

  • Before ordering, ensure your rod and crankshaft combination fits your block's deck height. To calculate your deck height, you will need to know your stroke, rod length, piston compression height, and piston depth at the top dead center: stroke/2 + rod length + compression height + piston depth at tdc or—if you have piston pop-up. 
  • For high-RPM or stroker builds, consider upgrading to a forged piston for added strength.
  • This Piston does not fit the Ducar/Tillotson 212E or Predator 224 Wrist Pin and Rod. You will need to use a Honda/Clone-Based Rod. 

FAQ

Frequently Asked Questions (FAQ)


Q1: What engines is this piston kit compatible with?

A: This piston fits most Predator 212cc (Hemi and Non-Hemi) engines and other GX200-style clones using a 70mm bore and 18mm wrist pin.


Q2: What is the advantage of a flat top piston?

A: Flat top pistons increase the engine’s compression ratio, which improves combustion efficiency and power output—especially beneficial for performance builds.


Q3: Does this kit include everything needed for installation?

A: Yes, it includes:

  • 70mm flat top piston
  • Piston rings
  • 18mm wrist pin
  • Wrist pin clips


Q4: Do I need to modify anything to install this piston?

A: For stock engines, this is a direct-fit part. However, if you’re pairing it with aftermarket rods or high-lift cams, verify deck height and piston-to-valve clearance to avoid interference.


Q5: Is this piston forged or cast?

A: This is a cast aluminum piston, suitable for most standard and mild performance builds. For high-RPM or racing applications, a forged piston is recommended.
