Casper's day at the track was cut short because the harmonic balancer was starting to fail and kept throwing the belt.

This harmonic balancer is the original that came with the truck.

If you want to spin past 4000 rpm, you should consider not running the OEM unit. We are putting on a SoCalDiesel unit and will report back on it.

Glad nothing bad happened Pat. Nothing like losing brakes and steering at the top of the track.
