Hi, All
We're about to upgrade the suspension on our 2018 310GK. We're either going to go to Dexter 8K axles and 4K springs, or the MORryde IS. The MORryde is significantly more expensive (comparison numbers below), but from the reviews here and on other sites it seems the owners are happy with their decision. I've also read, but can't find it again so I'm not sure that it was here, that owners going from 7K traditional suspension to 7K IS are happier than those that "upgraded" to the 8K, because of the harsher ride that necessarily gives. But since f=kx, I'll get a harsher ride with the Dexter 8Ks as well... So I'm looking for experience from any IS owners, and particularly from any who went to the 8K version on a rig that originally had 7K axles.
And for owners who upgraded to heavier traditional suspensions, are you happy with those?
I know that nothing post-factory can ever change the "yellow label" GVWR for a vehicle, but I will feel more sanguine with a beefier suspension. As full-timers, we have a friendly, close, acquaintance with the GVWR.
Another advantage to going with the IS is that MORryde assures me that they will set the suspension to tow level. With a 2018 F350 dually, we're towing about 2" nose high, and my per-wheel weighings confirm that the rear wheels are carrying more load than the fronts.
Now, about IS installation site: Mail from MORryde today (Jan 20, 2020) stated that the IS can be installed by MORryde (I assume in Indiana, but that wasn't stated), or by Henderson's Alignment in Grants Pass, OR. Those are the only two places. So the question: have any of you had Henderson's do the work?
Now the promised price comparisons for Dexter 8K upgrade vs IS (we already have 8K Kodiak disk brakes on the rig, so no brake upgrade).
From Performance Braking, quoted Jan 19, 2020 at the Quartzsite "Big Tent" show:
Dexter 8K axles (2) and 4K springs (4): $1,300
Installation: $400
Brake adapter plates (7K and 8K axles have a different bolt pattern for affixing the brakes): $33 / wheel: $132
Total quoted: $1,832
From MORryde for install by MORryde (quoted Jan 20, 2020):
7K: $3,999
8K: $4,559
Replumb brakes: $200 - $250
Thanks for any info!
