SumoSprings

I have a 2000 Georgie Boy (F53 frame). It already has anti-sway bars installed. The issue I have is that my tail end is a tad low in that when I pull into a drive way with a deep dip, my towing hitch scrapes the asphalt or concrete, filing away the bottom. I have 3 questions regarding SumoSprings:

1.) Can they provide my MH a couple of inches more lift in the rear and help prevent my hitch from dragging (I only need an extra 1-2 inches elevation)?

2.) Will installing them conflict with my anti-sway bars in any way or is it perfectly fine to have both?

3.) Can I just install just the rear springs with an "Option" to install the fronts later at my convenience?

Thanks ahead of time to all who respond.

There was a HUGE difference in the way it handle and drove. I believe its not an option anymore on Tiffin motorhomes its standard equipment..


    From what I understand, unloaded, the Sumosprings will not add any additional lift. When under load, they will help prevent/bolster sag ... which is not the same as providing lift.

    It depends on which weight you order. They will add some height just because of a stiffer spring feel. They do not allow the springs to fully flatten out under normal load.

    Sumo, Trembren, or Air bags will help you problem. If you go Air Bags, install the system 10forty2 did, a adjusting the air bags is akin to trying to check the inside dual without any valve stem extensions. It gets old fast!

    Firestone Ride Rite airbag helper springs are a good product. I put them on my coach a couple months ago and they really improved the ride and the handling. My coach is suffering from a sagging spring on the driver's side front and the Ride Rite is able to augment the spring to help re-level the coach and improve handling by doing so. I opted to go with the on-board compressor and the 4-corner control system as well so I can control the airbags whenever I want without having to pull out an external compressor. I did the installation myself, in my driveway at home.

    I have Sumo springs on all four corners. They are like a pillow that cushions the upward travel of the suspension. They provide no lift. They work fine with all other suspension components. And you can run just two if you want to.

    Good luck.

    If the motorhome is sagging in the rear from too light spring rate, add a leaf or 2 to the spring packs.

    If it has plenty of rear spring rate and simply needs more ride height, add spacer blocks under the spring packs.

    Most factory stock 4wd trucks use the same rear springs as their 2wd brothers, but use 2"-4" spacer blocks under the rear springs to gain the additional suspension height 4wd's are known for. The blocks are tapered and installed in one direction only, which rotates the front of the axle up slightly, to line up the driveshaft. You can do the same for your motorhome as is done with 4wd trucks.

    Add two AirLift air bags to the rear so that you can inflate or deflate them as needed.
