The system is a drop-in cylinder replacement that is universally compatible with a wide range of gearbox versions that have center-line nozzles. Similar to its sister product, the F1, it replaces the original gearbox components with a programmable pneumatic system allowing for higher performance and greater reliability over a gear driven system. Although economically priced, JACK™ still retains the same performance and quality you have come to expect from PolarStar products.
