These 4 5/8" springs do a great job. I was tired of popping the hatch and having to manually lift it. Now, it will knock you out.
Several times, the hatch would pop open by accident. The diamond key is not suited to being in pants pockets. I've accidently opened all the windows and sun roof. Even left it unlocked overnight. If I accidently hit the hatch button, I know. The hatch pops open all the way up.
I have videos too. I need to upload them to YouTube.
