Welcome to Killer RC
I got mine installed and man this is nice! One of the best mods I۪'ve done in a long time. Everyone should have one of these switches installed.
These shock limiters are a great must have upgrade.
I have the rear turnbuckle pro kit. It eliminates the baja's weakest link in it's suspension arms, without adding all the extra weight, and cost of going to aluminium arms which IMHO is a waste of money.
I fitted a Killer RC kill switch a couple weeks back and today I finally got the baja out and tested it out, and i actually needed the killswitch on the first run... the battery had vibrated loose. Without a kill switch this would have resulted in a runaway baja. What an amazing piece the killswitch really is.
