Can Roadmaster Comfort Ride System Install with SumoSprings on Trailer  

Updated 04/06/2026 | Published 04/03/2026



Question:

I have read some reviews that say you cant use the SumoSprings with the Roadmaster Shock absorbers and some say that you most certainly can. I have a 2022 Grand Design Reflection 337RLS with 6000lb Dexter axles, I currently have the SumoSprings TSS-107-47 helpers. I would like to install the Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers - 5,200-lb to 7,000-lb Axle along with the SumoSprings to help smooth out these horrific roads we now have. I asked SumoSprings and they said they should be able to be mounted together, but no definite yes answers. If I buy the Roadmaster Shock kit can I mount them with the SumSprings or will the SumoSprings need to be removed? Thanks for the advice, Dale

Hey Dale, you can install Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers # RM-2460 with a SumoSprings kit like the part # SS26MV. The SumoSpring would just engage a little earlier since it installs on top of the u-bolt plate which will be a little bit taller with the Comfort Ride system installed. Are you axles above or under the leaf springs of your trailer? The part # SS26MV is for overslung axles and the part # SS33HR is for if they are underslung.

The axles are under the leaf springs.

@Dale That means you have an underslung setup and would need the part # SS33HR.
