Product Description
The new ARC Racing billet "Long" rod for the PREDATOR 212cc. This rod measures 3.707" center to center for a 1.188" crank pin with .490" wrist pin and is designed to be used with aftermarket high-performance pistons. For stock stroke and high lift cam applications. The longer rod ratio generated with this combination will produce horsepower in the mid to high rpm range due to increased dwell and decreased side loading of piston. 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 depending on the block. ***
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 ARC_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.
