BLITZ/E-FIRESTORM/Ball diff for more precision.

Discontinued, replacement part: #86943

This ball differential is a standard replacement part on the high performance BLITZ ESE and features ceramic diff balls mated to a ball race and a steel gear ensuring smooth ball diff action without compromising the strength of the all-metal drivetrain. High quality outdrives 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.

This ball differential also fits the RTR BLITZ and E-Firestorm trucks as a high performance upgrade part that replaces the stock gear differential. Precision made to exact HPI factory specifications for a perfect bolt-on fit.
