Re: WD40, spacer dimensions???
There are several problems with using those. Although they are simpler to install than the steel spacers, they do not work in the same manner. The steel spacers raise the height of the truck by moving the coil higher up on a perch. This does not have anything to do with the coil. Though it will affect alignment camber.
Now, the rubber ones you are speaking of are inserted into the coil itself, like circle track or nascar style. This affects the coil spring. Compression of the coil is reduced. So your overall suspension travel is now being limited. These spacers can work themselves loose. I suppose if these rubber spacers were thick enough, they could acually increase the ride height as do the other kind of spacer, but the main approach with these is in stiffening the spring on compression. So, if you are happy with your springs feel now, and are just trying to compensate for added weight on the front, the steel spacer is the way to go.
