2018 Axis 25.2 Suspension upgrades - looking for part numbers

[keefd]

So I'm about to order suspension parts for my 2018 Axis 25.2. Based on an E-450 chassis.


Steering stabilizer: Roadmaster RSSA w/RBK24 kit
(pretty sure this is the correct set)

Sway bars: Hellwig 7718 Front/7180 Rear
(90% sure these are correct for a 2018 Thor Axis 25.2 on an E-450)

Air Lift 1000: Unsure. I think there were changes in the 2018 model year, and they are only listed for up to 2017 for the 80531 part number.

Moog end links: Moog's website shows the K750322 for 2017 and older E-450s but up to 2019 E-350s. Nothing for 2018+ E-450.

Sumo springs: Want to go with the Air Lift, but there's a ton of options on the manufacturer's website for front and rear Sumos. I'm confused as to which I should get if I go this way. What do y'all recommend?


Right now I'd be fine with doing just the steering stabilizer and front sway bar as the rear bars are sold out at many places. Found a rear bar on eBay though. Had an alignment done and it doesn't wander like a drunk sailor with stock suspension parts but it's still fatiguing on the highway. I've read a ton of threads but I was a little concerned since there seemed to be changes after 2017 to the E-450 van chassis.

I thank you for your time and advice.

Do the least amount of suspension work you can and add as you feel the need. Do the
Front sway bar first.
Go to a LEGITIMATE, not some tyrd lifts only, 4x4 place and get their opinion on shocks and such. 'Bilsteiin' is a brand, not a cure. The shocks on a 35' barely under gross weight rv are not the shocks for my little 24.1...no matter the name on the shocks or the chassis.

What you don't read on this forum is about those who go way overboard on suspension mods and wind up with little suspension travel, an intolerable tractor like ride, and they won't reverse the affects because of some ego.
I think we have only one member here who says the truth about the new sway bar he hates and just a very few, three maybe, who disclaim sumo's.

Do not fire the parts cannon at your suspension.
There are pictures of my suspension changes on the last(or close to it) page on my signature thread. I don't have sumo or sway bar or rear shock changes or a fancy stabilizer. I stopped where it worked...not way beyond where it worked. My front suspension is very radical, my rear suspension is dead stock except for some blocks.

I'm not saying the individual changes don't have value. I'm saying more is not more.

Sage advice indeed.

Just an FYI…
I did the Air Lift 1000 air springs as a DIY inside the front coil springs.
I like what they do for the ride
However, they do spring leaks.
For me, it was probably caused by the rubber rubbing on the steel surface. It’s happened to me twice, one on each side.

I’ve considered taking out altogether, but will probably see how long this fix works.

I received the free lifetime warranty replacement Airlift 1000 air spring bag.
Meanwhile I’m unsure if the bag actually has a leak or if a fitting briefly leaked when I lowered my hydraulic levelers too quickly, thus forcing air thru the hose connector fittings.
That is, it hasn’t leaked since I re-filled.
So I’ll wait & see.

Also, I just added Bilstein front shocks.
It was a fairly simple install without removing the tires and using the hydraulic levelers to raise the front end.

Here’s the Bilstein Front shock info…
