    • Good qualnkshaft clampl
Size: 3.308"
Parts look and feel of good quality and balance. Install was easy and everything fit without having to trim it shave crankcase at all. Piston has a arrow to face down in the cylinder and the connecting rod has two dots to line up at the crankshaft journal so make sure they're lined up and you're good to go. Have not fired it up yet but my predator 212 will be FIRE 🔥 I am sure. Building the custom exhaust now . Ported and polished the exhaust and the combustion chamber ported the intake and cross hatched the intake walls to optimize atomization. It's going to be a go-kart for the ages yes sir ... show more

Size: 3.308"
This wasn't the right kit for my application but I was able to use some items. Seemed quality. All parts were aluminum and the piston, connecting rod didn't have casting marks. Unfortunately didn't fit my engine though.

It was good until we took the gasket out and they ripped right in half. Also, the connecting rod only lasted about an hour before it broke. Do not buy this.!

I did a stage 2 upgrade to my predator 212 with no issues so far, I've only use the flywheel, connecting rod and valve springs.

    • Great upgrade to our custom build
Size: 3.323"+.020
We used this on one of our builds. Everything fit snug and the gasket sealed without needing to do any trimming. Even at high RPMs, the flywheel stayed steady. I was really impressed with how well and simply this worked and how easy it was to install. If you’re needing a replacement part, this offers a ton of value by being made with high quality materials. ... show more
