I had the same problem with my Bullet 251RBSWE. After consulting the Lippert spring charts I found that stock springs have 1 1/2” drop. Mine had sagged to 1 1/8”. I also discovered that the Keystone spec showed the East coast model uses 14” wheels and the West coast model uses 15” wheels. After consulting with Lippert engineers they confirmed that they build the frames/suspension the same for east and west so the 15” wheels will definitely be closer to the fender. Their engineers suggested that I go up two spring weights, to the 2200 lb,with 2” drop. (Normally only one spring weight, but they concurred I needed to get more spacing and the slightly heavier spring wouldn’t give as much). Thishas solved all the problems.
