HPI Blitz Ball differential
Now available from HPI as an option part for the Blitz RTR, replacing the standard gear diff, this ball differential comes directly from the high performance Blitz ESE. Featuring ceramic diff balls mated to a ball race and a steel gear, it ensures smooth ball diff action without compromising the strength of the all-metal drive-train. High quality out-drives ensure long part life. The diff is easily adjusted with a 2.5mm driver so you can tune the feel to your driving style. The diff also shaves 20g of rotating weight from the gearbox.
