21. Here is the system once it’s completely installed. The Pro-Track II system is nice and compact keeping all the accessories in front of the head. This means it doesn’t infringe on the valve covers so we can run whatever we want. We think the kit looks killer in our black and polished combo, but can also be ordered full polished or full black as well. Now we can drive whoop on the car knowing our accessory drive system is awesome and won’t toss the belt.
