The Strong Arm lift supports were a direct replacement for the OEM parts. They're not an exact OEM match, but I prefer the Strong Arm design. The two ball joints of the OEM design are built-in to the lifts, which make them just a bit more difficult to remove. The ball joints of the Strong Arm lift are independent of the lift, and after tightening the ball joints into the frame of the car and the frame of the hood, the ends of the lift simply snap onto the ball joints. Overall the removal and installation took about 20 minutes.
