Whats a good door popper kit?

Im looking for a door popper kit for the doors of my ram. Its gonna be a daily driver so i need something thats gonna last and get me through a winter if i need it too. Ive been looking at some 50lb autoloc kits on ebay and I wanted to know if those or good enough or if i should go bigger. I want the doors to pop way the hell open when i hit the switch.
