XAndy I am very interested in how the RAS turns out. Nissan Customer Care finally called me back today but don’t think it will go far. Waiting on another call back while he checks to see if they have a TSB in the works. I want something in writing from them saying it is OK to install an overload spring before I do the RAS. The RAS for the X requires pinning through the leaf pack so it isn’t a 5 minute job to remove.

The Timbren bump stops are a safer bet to not void the warranty however aren’t perfect. On unlifted vehicles a few people have complained of limited travel of the springs. A couple others talked of rebound causing the rear end to break free on the road. It would be great if Nissan would just fix it for us.
