Xray 1/12th pan car solid rear axle set
Coming from Xray and made for their X12 series of 1/12th scale pan cars is a solid rear axle set. It replaces the standard diff for a spool axle that improves acceleration and steering in high-traction conditions while offering a low weight, perfect balance and vibration-free running. The axle is made up using a carbon fibre axle shaft and an aluminium wheel hub system and it is also usable on other brand cars.
