CRT x2 Front and rear pinions on X1?

[riverat1540]

just wondering if the x2 10t pinions will fit the x1 crt diff ring gears or do u have to change out both? trying to change from buggy ratio to truggy ratio and want to find the easiest way without using the 62t spur

You have to change the pinions and spurs. The X2 diffs are spiral cut.
