Product made a huge difference when towing my travel trailer. Installation was very easy took about 30 minutes. Definitely worth the money!

Amazing product! Unlike air bags, when weight isn't on the backend of the truck the system is completely disengaged and rides like normal. Once weight is added its engaged and assisting the load for you! Awesome product and awesome customer service!


Have a set of those on my Xterra for about 5 years by now. Ordered one more for my wife’s PRO4X. Worth every penny. No more hard landings on the axle when truck is loaded on a bumpy roads.
