Question:

I am considering the Timbren rear suspension for my 2026 Ram 3500. Ill be carrying the weight of my 5th wheel, Alliance 32RLS weighing 14000 lbs. Im not a full timer but we will be using most likely at least monthly on long trips. which of the two Timbrens do you recommend, the 8000 or the 8600?

Hey Carlos, welcome back! The Timbren kit you need for your 2026 Ram 3500 is definitely the # TDR3500CA which while it does have the higher capacity is the better and less harsh option compared to the severe service option part # T94VR that also fits your truck. The kit I referenced will give you the support you are looking for without killing the ride quality so it is for sure what you are looking for. How you towed the Alliance yet?

@Carlos Makes sense! Yeah they can be really helpful especially when towing.

I put these on my 2007.5 3500 SRW. While they help the sag from my 5-wheel RV, the ride without a load is so bad people do not like riding in my truck. If I had to do it over again, I would buy the airbags.

@JonathonR I would actually recommend the RAS kit part # RAS3613-HD instead for you as it will give you the support and ride quality you are looking for.

@JonathonR if installed correctly, it won’t change stock ride. Air bags won’t make your stock ride any better. I’ve done both on two trucks.

They are installed correctly. There is just not much room between the axle housing and Timbren so I feel every bump in the road.

I put these on my Ram 3500 5th Gen. I have a Cabober camper so I am right at my GVWR and it really helps with not only suspension but the side to side.

Carlos i installed these on a 2024 3500 towing a DRV that weighted out at 24325 #. They worked great , did not effect ride when empty (which ain’t much of a ride being a3500) i have been using timbrens in the towing equipment indrustry for 30 + years ,much simplier then add on air ride ..
