You have to be carefull adjusting ride hieght with the spring preload adjusters because you can quickly take a shock out of its operational range. We used to run into this all the time on drag cars. People thought you could just adjust the spring up and down to raise and lower the car, and we would get cars that either had the shocks completely topped out or bottomed out. You can probably go about 1/2" on the shock from suggested installed height, but once you go past that you will have problems. If you need more adjustment than that, you need either a longer or shorter shock, or an adjustable mounting position.
