Works as advertised. Defiantly a better ride so far.

While it is not air ride, it is a dramatic improvement over OE. I have only had the Thor Windsport out on short trips, but look forward to testing it on a long journey to Florida, soon? Did the front and back.

Installed on my 2009 Ford F-53 chassis Four Winds Windsport model 32A. Improved the ride pretty good. Less sway noted and softened the bumps well!

If removing rear duals, drilling eight 3/8" holes in the hardened chassis frame and triming motorhome 'studs' all while dodging breaklines and electrical wiring is easy, than this is an easy install.I had already installed rear tracBar for stability. These sumo springs probably also help with stability.My goal was a smoother ride. With a motorhome there is always crashing and banging sounds as you drag your house down the highway. With this install the jarring is noticably reduced!

Added Sumosprings to front and rear of my 2011 Damon Daybreak. The change in ride and handling is unbeleivable.

Package arrived early, everything is well packed, nothing missing. I've dry-fit the springs and they seem to fit well. Actual installation will not be until spring, when the snow is gone.

We found an article in a motorhome magazine about these springs. After driving only 2000 miles in "Sprinkles" the 40ft RV, I was becoming painfully aware of her high profile and her nature in crosswinds. So, because it is un-nerving to other drivers to see the driver of the massive RV in their rear view mirror crying, screaming, and struggling against the wind, we thought we would give them a try.I was getting pushed over when trucks would pass and cross winds were a nightmare, but no more! SumoSprings for the front and rear end are amazing! They push and pull in opposite directions depending on the force acting on them. I'm not going to go into all of the science stuff on how they work, just know that they stabilize the coach and help to keep it level and smooth.I was able to install them myself in just a couple of hours with some very simple tools (I did have to buy a drill bit that cut through steel at Lowes).I LOVE the difference these made to the vehicle and its performance.I recommend that you get on the manufacturers website, find the size that fits your coach, then get them on Amazon.

Definitely corrected the swaying problems when big rigs would pass or high winds, and turning on sharp uneven curves. I would highly recommend it. I bought both front and rear sets.

Installed front and rear on Thor Windsport 31s motorhome, WOW was a difference in the ride and handling. Was not too difficult to install. Make sure to order the correct ones.
