Ford F53 Motorhome

Ford F53 Class A Motorhomes are the biggest vehicles on the road — and they demand the strongest suspension support. SumoSprings are built to handle heavy, constant loads without sacrificing comfort of your Ford F53 based motorhome.

An Essential Upgrade for Any Ford F53 RV Owner

Manufactured from our micro-cellular polyurethane, the F53 SumoSprings suspension kit is designed to immediately improve handling, & remove sway, and decrease vibration in your motorhome. With zero-maintenance, these airless air springs increases overall driver control and ride comfort and will outlast your coach.

What Our Customers Are Saying

After installing SumoSprings on our Tiffin Allegro, the improvement was immediate. The constant rocking from passing trucks is gone, and the steering feels tighter and more predictable. Long driving days are far less tiring, and my wife says the interior feels quieter too. It’s the kind of upgrade that makes you wonder why you didn’t do it sooner.

Daniel Harper

2020 Tiffin Allegro Open Road

We were hesitant at first, but SumoSprings completely changed the ride of our Bay Star. Before, crosswinds and uneven roads had us fighting the wheel, but now the coach feels planted and controlled. The sway in curves is dramatically reduced, and it feels like a more stable, comfortable motorhome overall. Highly recommended for Class A owners.

Susan Clark

2021 Newmar Bay Star

We’ve logged thousands of miles in our Bounder, and adding SumoSprings has been the best upgrade so far. The ride is smoother, the handling more stable, and the coach doesn’t lean or bounce nearly as much. Even after long days behind the wheel, I feel less fatigued because I’m not constantly correcting the steering. A big win for safety and comfort.
