The word Timbrens keeps showing up in the TowRig.com stats as a search term so we might as well discuss them, what are they exactly and how do they work?
There basically like a bump stop that is an active part of the suspension. Using them results in effective higher spring rates (and resulting load capacity) and often results in some negligable lift as well. Sort of like stiff and non-adjustable airbags in effect I guess. Never used them, but that's what I think I know...
