Description

Wildcat 70.25mm Flat Top Piston Kit – Lightweight Racing Upgrade for Clone Engines


The Wildcat 70.25mm flat top piston is a lightweight, high-performance upgrade for small block engines using a 70mm bore and a 58mm stroker crankshaft. Engineered with a shorter skirt design, this piston provides improved clearance, reduced weight, and better performance over traditional 70mm factory pistons found in Predator 212, Tillotson 212, and other clone engines.


Specifically designed to work with the Wildcat 223’s 58mm stroke crankshaft and a Honda/Clone-based connecting rod, this piston makes it easier to retrofit 58mm stroke cranks into a wider range of engine builds.

FAQ

What engines is the Wildcat 70.25mm piston compatible with?

What connecting rod do I need?

You’ll need a Honda/Clone-style billet connecting rod with an 18mm wrist pin diameter. This piston is not compatiblewith the factory rods found in the Predator 224 or Ducar/Tillotson 212E.


What are the advantages of this piston over stock?

  • Shorter skirt design improves clearance for stroker cranks
  • 20g lighter than most stock 70mm pistons
  • Improves throttle response and reduces rotating mass
  • Ideal for performance mini bike and go-kart builds


What’s included in the kit?

  • Complete piston ring set
  • 18mm wrist pin
  • Two circlips


Can I use this in my Tillotson 212E, Ducar 212 Ghost 212 or Predator 224(Non-hemi)?

Yes, but only if you’re also using a Honda/Clone-style billet rod. It will not work with the Tillotson/Ducar/Ghost 212 or Predator 224 Non-hemi’s OEM rod due to wrist pin size differences.
