JEGS SFI LT1/LS Harmonic Balancers

Product images may differ from actual product appearance.

If you turn 12,500 RPM (on purpose or not), our high-performance balancers can handle it.

We start with a chunk of 1045 steel, meticulously CNC machine it and fully balance it into harmonic art that meets SFI 18.1 specifications. That's good enough for pretty much every type of racing that there is. Permanently etched timing marks every 2-degrees with additional marks at 90° increments.
