For the new Harbor Freight PREDATOR 212cc  This rod measures 3.707" with .490" wrist pin and is designed to be used with aftermarket high-performance pistons.* Bearings and custom designed high tensile strength bolts are included.

*** Piston will require machining in this application. Approximately .075" will need to be remove from the piston dome. ***

All of our rods are CNC machined from aircraft grade 7075 T-651 aluminum.  Our OHV rods are designed to utilize the higher compression ratios and high RPMs of racing OHV engines. 

 Key Features Include:

  • Oil groove in the crank bore that is fed through a channel in the integrated dipper arm.
  • Oil groove in the wrist pin bore that provides a reservoir of lubricant to the wrist pin.

*The standard bore on a Predator 212cc engine is 2.756".  The Wiseco Piston #11132p94 is for a 2.756" bore, which means it will yield approximately .003" piston to wall clearance.  This is right where you want to be, so provided your bore is good and needs nothing more than a fresh cross-hatch honing, it will be good.  If your bore is larger, out-of-round, or the engine has already been run for a while with the stock piston, you will need to go with a larger piston.  Call us if this is the case.

Rod bolt torque: 170 in/lbs lubricated
