Xray introduce the active centre differential for the XB8 1/8th off-road buggy. The adjustable gear diff is made to adapt the buggy’s handling characteristics both on-power and off-power by using different shape internals. The standard 90 degree parts provide a good balance between on and off-power as the diff closes and opens with a slight delay, making the standard setting best suited for high-grip or bumpy tracks. The optional 120 degree internals let the diff close or open immediately which is a setting best used on slippery or flat tracks. The set includes all needed parts and it fits the XB8’14, the XB8’15 and the XB8E.
