Why didn't I get it sooner? I don't haul stuff on my Tundra all the time, but when I do the rear plates aren't heavy, so it's fun to ride with 1,600 pounds in the rear. But after installing Timbrens, driving is day and night. Even unloaded I don't notice any difference in ride quality and it drives MUCH better with lots of body than without the Timbrens. For example, for years past it was fun lugging a meter of clay home when I hit a bump, but now it's much, much smoother without the jarring of blades hitting the OEM stops.
