A question for those with the Mor/Ryde IS Suspension

I'm going to have the IS suspension and Kodiak Disc Brakes done on my 36RL in late May. Trying to decide between 7k and 8k axles. Cost difference isn't a factor.

The main reason for doing this is ride comfort while towing and safety (braking). Right now, last time I had the rig weighed, the coach has just about 12, 240 lbs sitting on the axles. This will probably change a bit as I am about to add the W/D and also a Onan genset. I think most of the Genset weight will transfer to the pin, but correct me if I'm wrong.

If you have done the IS and did the 7k axles, how did it work out and how is the ride and do you wish you had done 8k. Also, conversely, if you have the 8k, how is the ride and do you wish you had 7k .

There are a lot of reviews on the web. Almost universally everyone loves the conversion, but there seem to be quite a few with the 8k that said they still got a lot of "bounce" that surprised them. Even after Mor/Ryde "tweeked" it a bit.

Look forward to your answers.

The generator at 296 lbs splits just about even between the axles and the pin, and if I remember, the washer and dryer come in about 220 lbs and they also are mostly split. Fresh water favors the pin.

I can't say what the ride is like with the IS, but I would be inclined to go with the heaviest rated axle you could get.

I posted this on the other Forum, but will re-post here for those that aren't on the other forum.


We know we're traveling heavy, so we wanted the upgrade to the 8K and haven't regretted it at all.
Mor/ryde will take some measurements from the frame to the road, then back you into the shop and get you on their portable scales. From there they will suggest the best setup for you.
We have just about all the options except for the dishwasher so we're grossing will over 17.5K so we wanted the 8K system to go with our 17.5 H rated tires.
When we were headed to Mor/ryde we had canned Cat Food stacked in the entrance way closet and when making a Pit Stop, had to be careful opening the closet door to turn on the water pump and we might get an avalanche of Cat Food. Since upgrading to the IS we haven't had a problem and have even forgotten something on the Island Counter and it was still there when we stopped (now if we had to do a Panic Stop, all bets would be off)
We had the IS and Disc done on our Montana, so the RW was ordered with the Disc and would have had the IS if RW would have allowed, so it was in our plans to have it done when we could.
It's a great setup and I don't think you'll regret it either 7 or 8K system. If still unsure, ask the Techs what they think.

Good luck
