Jack, Bill & Linda and Howard have written about the MorRyde upgrade. Our 3650 RL Trilogy has dual 8,000 lb axels, correct track wheel alignment system, and 12" brakes. From what we've read we wondering if we should upgrade for safety. BTW, our Dually doesn't have an exhaust brake so we're getting it installed in Portland before mid-Sept by a highly recommended diesel mechanic. We have to go to the factory in Elkhart In October because of an issue we heard (lEDs on fron of rig has caused fires in three different Trilogys) about trying to schedule the MorRyde IS upgrade if strongly recommended While we're in the area.
We've had no problems towing or slowing but safety is #1 and we trust your recommendations. Just don't want to overkill and we are newer full-timers (thanks Howard & Linda 😄).
Label says 14820 dry and we can add 1269 lbs loaded in. We are very near capacity on that w loaded weight.
Thanks so much,
Sherry

Hi Sherry:
Well, that’s a interesting question in some ways as pertains to safety.You have 8,000lb axles. That covers one of the “should have.” So with safety as the foremost concern and in this order:
Goodyear G114 H Tires – Disc Brakes – MOR/ryde IS – with the Tires and Brakes actually tying for number 1.
Do the G114 tires and 8K Disc brakes – period – IMO.
BTW, Trailer Tire and Wheel will sell you the Goodyear G114 tires, on wheels, balanced and deliver them to MOR/ryde and MOR/ryde will install for you.That’s done all the time just like it was for Howard and Linda and another couple when we were there last week.You just need to make the phone calls to let everyone know what you want and "it will happen." (You would be surprised at the number of rigs in there getting the same thing.)
Is the IS “safer” than what you have as you have 8K axles? That’s a more difficult call.Will the rig ride better – can’t say for sure – never pulled your rig.We had “springs” along with the flex equalizer system and it wasn’t very good in comparison.So the IS was a huge benefit for our rig. Would I put an IS on a brand new trailer pulling the OEM supplied system off? - Yes - even before the fringe got cold.
That' my perspective.
Now it is Jack and Howard’s turn.

I agree totally with Bill.
Required: 17.5 AND H RATED TIRES AND DISC BRAKES. Every trailer should have disc brakes and overrated tires. Period.
Optional, but a very nice upgrade: Mor/Ryde IS. We have had IS on 4 trailers over a 13+ year period fulltiming. It makes a huge difference in the ride and interior "trashing". I would not own a trailer without it. Plus it cuts down on maintenance a little. Is it a "safety" feature ? Well, not in my book, but if I was keeping the trailer I'd do it.
OK...Howards turn. :)

I have no idea if this information has been mentioned in this forum. I'm just posting it for information purposes.
Doing a little math on the specs from the OPs trailer indicates it has GAWRs of around 7500# each. The trailer's specs call for 8000# axles. The common practice with axles being too large for the vehicle's GVWR is to derate them to a value that coincides with the trailer's GVWR. Vehicle manufacturers are allowed to derate axles, the procedure is described in the vehicle certification regulation. It is also noted in the tire/rim regulation for vehicles above 10,000#. A quick check of the trailer's certification label will verify that 7500# figure. It's really the only way the manufacturer can put the GY LRG tires on the 3650 models.
The upgrades mentioned are very desirable for heavy trailers. But, remember the full load capacity of the 8000# axles cannot be used without overloading the trailer 1000# or more above GVWR.

Yes tires, yes disc brakes. Trailer tire and wheel will ship to any place in Elkhart that is working on your rig. You pay modest delivery charge from Illinois location, and save sales tax. Mine were balanced with graphite powder by them. Lost air bad valve extender), and the powder prevented the rim from reseating - repairman had to vacuum it all out and said i should have asked for the balancing pellets instead. This is what he put back in.
I believe that when you start talking to MorRyde that they will tell you that a rig your weight should go with the 7k IS, not 8k IS setup. The brakes and hubs on both 7k and 8k IS are 8k, but the geometry of the 8k (shorter trailing arms) makes it difficult to get a smooth ride on the 8k IS. When i did mine 17 months ago, they wanted camp ready-load on axles to be more than 97% of 7k (6,790#) before going to 8k axles. I was no where near that, but because of my heavy side did have 3,450 on one tire, so they put a stronger rubber on that side of the 5er.
I think the 8k setup you have now provides a good safety margin and also avoids the harsh ride via its overload springs that are not in play due to your less than 7k load. Your larger drm brakes are way better than 7k drums, but still suffer from fade from heat, and are equally sussiptable to broken wires impacting performance.
If you don't have the MorRyde rubber center pivot (ER system?? I think), i would say upgrade to that or IS. If you do, and you have the rubber inspected and its ok, i would keep what you have for axles/springs, but upgrade the greasable shackles if you don't already have them.
You will find MorRyde great folks to work with they will advise you of your options for your actual weight (they weigh each wheel before and after), and will do whatever you want.
Count on two full days to get IS and disc brake controller, lines etc. I don't know if they could get the brakes alone done in one day, but they would tell you, and advise you if you need a adapter for your current truck brake controller, can use as is, or need to replace it.
