Most Popular Extra Heavy Duty for 2002 Fleetwood Bounder Motorhome

Great product and great company to deal with. Highly recommend Etrailer.

Wow, what a difference. Installed on a 2005 Allegro Open Road 30 ft motorhome that has a 2004 Ford F53 chassis. It raised the front ride by an inch or two, so it looks less "saggy" up front. Also took the chatter out of a lot of small bumps in the road. MH feels much more stable on the road and has less roll/lean when corning. Install was pretty straight forward. Only have about 40 miles on them to date, but will give them a good test on a 1200 mile trip in a few weeks.

The installed system works great. The installation was WAY harder then the video suggests because of the limited space to work. Maybe a bit misleading

The on the high seas sway is gone thanks to the sumosprings and roadmaster sway bar I installed.

I replaced both the front and rear Helper Springs with the Sumo Springs. The difference in the handling and ride of my 36 ft Class A Motorhome was amazing. My only regret is that I didn’t do this years ago. With the old helper springs when an 18 wheeler would pass on a two lane road the motorhome would rock but with the new Sumo Springs I feel almost nothing. The difference has made driving much more enjoyable.

Sumo springs along with a steering stabizer, new shocks, and oversized sway bars seriously tightens the ride on older model RV with an f53 ford chasis. Long hauls become a lot less strenuous. I also put a memory foam and high density foam seat cushion on the driver's seat. We can travel all over with a lot less fatigue from fighting the wheel and pucker factor from blowing around the road. I took about 3 hours to unstall all 4 sumo springs.

I called because I couldn’t find the right part number on front and back sumo springs for my National RV. Joshua put together a quote in no time. George confirmed my order and walaa I was smooth ridin’ like a dream! Thanks etrailer!

These “overloads” are such a great answer to suspension needs! They are made with high grade materials and the installation was a snap! I would buy them again many times over! Don’t mess with air bags, compressors, air lines and all that “stuff.” These are the deal!! Pictures of before and after. Simple way to add significant suspension payload quickly with little fuss.

Great addition to the rear end.

Easy transaction parts for perfect!

What a big difference these Timbren SES make. No more side to side sway like it was. They DO as they say. I also put them on the rear.

Install was straightforward. Instructions are pretty good and easy to follow. I paired with an onboard air compressor with wireless control which makes adjusting air pressure in the bars super convenient.

Very well madel. The installation videos that etrailer has really helped and made it very easy to install, and if you had any questions, you could go back and watch the video again. I shopped around and E trailer had the best price of anyone. The customer service team was very nice and helpful with the order.

I received my air lift lifter didn’t have all the parts that I needed called them direct their shipping them out, but it will take a while

Thank you for fast shipping . I like buying from you guys great servise

These were perfect for our E450 Dynamax Class C motorhome. They really enhanced the ride and handling. They raised the motorhome overall about an inch and and quarter. I would definitely purchase again.

We ordered the sumo springs for our 2004 coachmen freedom series. The order came in just a few days as they did when we bought a heavy duty rear stabalizer last year. While I waited for the order ,myself and a grandson put the rear of our rv up on 7500 lb jack stands, two would have been fine but I wanted two more just in case. We took the rear duals off to make the installation easier ,and it was. Instalation went well,only having to move the gas line on passenger side up an inch by moving a clamp.We hoped these would help the light steering issue and related pushing from side when we would get passed on freeway. Not only did it clear up these issues but also quieted the coach down some. All my tests where done at highway speeds with the towed car behind. Thank you again to all at etrailer! Don. Ps.
