These flywheels are the cheapest alternative to billet that you will find yet and not sacrifice safety.

This is what BSP says about them:

Now approved for NEW AKRA Economy class. OEM Cast Aluminum Flywheel for Box Stock Project and clone engines. Fits the same tapered crankshaft as most aftermarket clone flywheels. It's BALCO certified and spin tested to 10,000 RPM's. Weight is 3.18 pounds.

I have used these on many builds and felt they were a great addition to my selection of parts. They usually degree in at 18 deg with the stock key so using a nice 8 deg key would be ideal in many cases.

They lap in to 196 clone, bsp 212, dukar 212, tillotson engines, honda gx and many other honda style tapers.

They DO NOT fit hemi predators

Note: They are not the correct taper for non hemi predator however many people are lapping them in to non hemi cranks. ( i dont recommend it but it does work )

I see on the Facebook pages about once a month that guys question if the lines (that they think are cracks) are cracks. The answer to that is NO they are NOT cracks, they are casting mold marks or flash and will not lead to failure.

If this will sit wrong in your mind then buy a billet flywheel instead. Thankfully nobody I have sold these to has questioned it but I'm sure I'm due, so again if your that guy buy billet instead.
