Shock Absorbing Equalizers Or SumoSprings For 2021 Grand Design Imagine 2400BH  


I have a 2021 Imagine 2400BH and want to upgrade the suspension a little. I’ve been wanting the Morryde CRE3000 or the Road Armor. I also researched the Sumo Springs and was wandering if using the Sumo Springs in conjunction with the Morryde/Road Armor a good idea?


Helpful Expert Reply:

There would be no issues with using the SumoSprings like the # TSS-107-40 with the Road Armor or MORryde Upgraded equalizers.

With that being said, I would upgrade your equalizers first, and I think you will find that they will provide the suspension upgrades you are looking for without needing additional components.

To determine the correct replacement equalizers, you will need to know how long your current equalizers are between the horizontal mounting holes to to keep your suspension geometry the same.

For example the Road Armor Shock Absorbing Equalizer Kit # LC696740 measure 6" center to center of the horizontal mounting holes as shown in the included diagram, so if your current equalizers are the same length these would be a great option for you.

If your equalizers are a different length, just let me know and I would be happy to recommend the correct equalizers for you.

I included a video of all of the products mentioned for you to take a look at.

Hey Samuel, I have a dual 7000 lb. axel fifth wheel with 33 inch spacing that came with monroe 33033 shocks. It is underslung as well. My equalizers are 6 inch horizontal spacing. Everything is dexter brand. I have been looking at the sumosprings as well as the road armor or the MORryde Alltrek 4000 equalizer. The dexter e-z flex will not work for me as their heavy duty option is only for 35inch axel spacing and the horizontal measurement is over 7 inches. Anyway, you stated in your reply to frank that he should the equalizer before trying the sumosprings. Could you elaborate on that a little? Also which equalizer do you prefer? And is the Morryde x-factor crossmember something worth considering? My trailer is 12000 lbs, and I have about 1.5 inches between the 16 inch tires. Thanks, Guy

@GuyW Above I told frank to measure his equalizer to find the correct replacement. Axle spacing does not determine the length of the equalizer, so it's important that you don't go just off axle spacing, but off the physical size of the equalizer currently installed on your trailer. Leaf spring length and equalizer length play a part in axle spacing. I would go with the MORryde option in your size. Most cushioned equalizers are pretty similar, but I think the MORryde quality tends to be the best, and I've had the best personal experience with comfort when using them. Since you're trailer is underslung I wouldn't worry about the crossmember. It will stiffen up the hangers, but in my experience I only ever see issues with trailers that have overslung springs causing higher center of gravity causing a higher chance of issues with the hangers bending/moving etc.
