This is the belt length tested and recommended for a '20+ GT500 running the Apex Predator Hub and VMP 2.6" 8-rib pulley.

Fitment was tested on a belt drive system that was otherwise stock in regards to tensioner, idlers, and crank pulley size. Changes in tensioner, idlers, or the utilization of an adjustable upper idler may alter belt length requirements.

For 2.7" pulleys, we recommend K080702.
