VERY effective! Simple installation. Truck is super sturdy now under weight and smooth driving when bed is empty. When my camper is hitched there is zero rear sag and perfectly level. Great product!

I bought these for my 2016 Crew Cab Silverado 2WD because I started pulling a heavy trailer. It does exactly what I need it to do. It helps support support some of weight so that the back end doesn't sag when the heavy trailer is connected. Also, it has no effect on the ride without the extra load because they don't touch the axle under normal loads. Simple design, easy to install. Genius.

Works well easy to install no more air bags that leak down and no more worries about having pressure in the bags so they don’t get pinched

Just got back from pulling a 27' Gulf Stream in the Mtns. of NC. These were a worthwhile addition on top of our Weight Dist. Hitch. No sway, no sag. Easy install. Was noticeable as soon as I left with camper hitched. Not bad at all empty, perfect addition.

Very easy to install. Only took about 15 minutes. My Silverado has better handling in turns and much more control and support when hauling my camper and boat. I have less sway and more control when hauling. Only con I have is normal ride comfort due to only have about an inch between the frame sumo spring.
