Polarstar Jack HPA Engine
Similar to its sister products, the JACK™ 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, the JACK™ still retains the same performance and quality you have come to expect from PolarStar products. The JACK™ has only one moving part, the nozzle, which acts as its own poppet valve.
