Review on Timbren FR350SDF Suspension Enhancement System by Tommy Rao

My husband has wanted to add this to our 2006 F350 double cab for YEARS but didn't see the point. This spring I finally gave in, ordered it and he put it on in about 45 minutes. The next day we set off on our first hike of the year with our large horse trailer with 3 horses (approx. 15 km). The difference in the trip was INCREDIBLE. A section of the freeway that is usually so bumpy that we have to brake below the posted speed limit appeared to have been repaved (it wasn't). The ride is much smoother - crossing uneven train tracks when towing a trailer is no longer a problem. And our truck no longer sinks when fully loaded with our large trailer. What I don't understand is why such a suspension system is not standard on large one ton trucks. The original my husband deleted and replaced with this one looks flimsy.
