The LSD door system consists of a specific door hinge which initially opens the factory door 30 degrees outwards, like a common car door and then upwards by the support of a gas shock with minimal effort.

The door opens in 2 steps:

Step 1: Open the door outwards as usual to a maximum angle of approximately 30 degrees. Allowing comfortable access to enter and exit the vehicle.
 
Step 2: Lift the door after reaching the opening angle of 30 degrees. This is done with ease as the door is supported by the gas shock to an angle of approximately 40 degrees.   
The LSD door hinges are installed at the original mounting points of the dismantled factory hinges. A range of adjustability is built into each LSD door hinge for perfect alignment and operation. Additional features also include limits that prevent the doors from being open too far as well as avoiding contact of the rocker panel.

Safety and quality are LSDs highest priorities.

Valuable research and development of materials and data is integrated into our LSD product.

LSD hinges have been tested against the hinges of our competitors using the tensile force comparatibe test with superior results.
