Linear actuator help

In search of knowledge, I am using a RoboClaw powered by a switching power supply to run two Linear Actuators (ServoCity SDA 12-263) and I am running into trouble with transients. I am pretty sure  that I need to make either a voltage clamp or a snubber to deal with these spikes but I don't know which is appropriate or how to calculate the required values. My google foo has failed me and I was hoping to have a kind passer by send me in the right direction. 

More specifically the caps in side the motor keep exploding. My understanding is this is cause by over voltage and so it must be transients from when I change directions quickly..

Thanks in advance
