Emaxx driveshaft options

i was out in the desert yesterday with a buddy and broke a driveshaft. does this part normally break? i must have hit the ground pretty hard after the jump because the 4 spike ball twisted all 4 corners on both the front and rear of the rear driveshaft. what are my options for replacements? i bought the sliders and they came with 2 sets. i got 1 set on and the other i'll use for a spare. i assume that's my least expensive alternative.
