This lift strut allows the trunk lid to go up completely. It does not fly up, but rather goes up at a nice rate. It also closes nice, and it minimizes the chances of the lid slamming shut.
I used one strut for a stock trunk without spoiler, and two for a stock trunk with a factory spoiler.
You will need the following parts for one lift strut installation.
