I know a lot of people have done that. I am curious what springs you have. I am using springs from a 1982 300SD. They have a higher spring rate and are a similar length to the original wagon springs. With the SD springs, the car is nice and level even without the sls system working... as long as it is not loaded. However, I frequently carry heavy loads or pull a trailer with some tung weight. The sls is very helpful. I am all about keeping things simple, but I am not ready to scrap the sls yet. It is a system that is worth keeping.
