the rc quick disconnects are great for a "budget/starter" quick disconnect. i have them on my wifes jeep because they came with the lift kit, and also explain to my customers that they are great "budget disconnects", but aren't as good as the JKS ones for example. so yes they can be a bit thight. any kind of un-even ground will make them harder. if you can get a second hand, or possibly even by yourself, slightly knudge/rock the jeep as you pull the pin, you'll notice that they will come out easier.
