E450 Suspension Changes/Upgrades

Is there any chance you posted about the suspension changes/upgrades you made?

We just purchased a 2019 Thor on the E 450 platform and I'm thinking the ride could be made better with some upgrades as well, mainly shocks, sway bar and tie rod/drag link (assuming it has one or the other or both).

We have a '22 Ford E450, purchased in 12/22. First, should have test drive this thing. It drove horribly bad. Felt very unsafe. If dealership was still open the evening we picked up the unit I would have returned it. Got it home and discovered the tires were 20 and 30 lbs. under inflated. Reviewed the walk through video they sent me the next day where it suggest to have the unit aligned. Unit is aligned by Ford before Thor adds the coach and all the additional weight. Ours was way out of alignment. I thought I was buying a rugged E450 like the F450 but that appears NOT to be the case.
Unit has a horribly bad tail wag. Have upgraded the Front and Rear sway bars, front and rear Sumo Springs and steering stabilizer to the Zero Center Point (I think that's what its called). A second alignment with more Caster. Handling much improved but still working on the tail wag. Problem worse when towing a vehicle. Improved shocks next.
Hard to believe spending that amount of money for a Coach that we have to spend thousands more to get the unit to feel save. Will never ride like a sedan but it should feel safe.
I try to inform everyone my frustrations who say they are looking for a camper, but also the joy we have our Coach.
Kind of a challenge for the retired.
Should we discuss the problems with the coach section now?
Manufactures really need to do a better job.
Don't forget to re-aim your headlights.

we put front and rear sway bars on ours. we were happy before the modification, put them on cuz it seemed like the thing to do seeing all the chat on this forum about it. after the upgrade there is a slight improvement when driving in a cross wind, or turns and such. that will be the last chassis modification for us. we are happy with the drive.

I learned to drive in the 60's on $50 cars and trucks with very worn king pins, blown shocks, and sagging springs. Put 85,000 miles on our 28A and have not changed a single suspension component. While it's no sports car, I have found after a few "K" behind the wheel it drives just as fine as a large marshmallow.

Personally, I am glad I did not spend $$ on suspension upgrades, your opinions may be different !

If your coach does not have a rear trackbar adding one will do wonders for the tail wag.

Also consider this, that F-450 will handle differently when fully loaded. Your Class C motorhome is a fully loaded vehicle!

Yes, I want through the same experience with my 2022 Thor Vegas; which, although Thor calls it a "Class A", the chassis is an E350 /E450, so I feel your pain; before my suspension upgrades, the coach drove and steered almost dangerously. Unfortunately, this is more the norm than the exception,

Same here. I learned to drive in the late 1960s in cars/trucks of that era... the handling was horrible compared to today's cars. Severe body roll and understeer were normal then. So you just learned to deal with it - it was the norm. Now I expect the motorhome to drive and handle like a U-Haul box truck. I anticipate getting blown/sucked sideways by passing semis. I slow WAY down when traversing entrance curbs and making sharp turns. EVERYTHING is a LOT slower in the motorhome.

I found that simply slowing down a little and enjoying the journey makes the drive a lot less stressful. Pushing a commercial truck chassis to it's limits makes for an ugly unenjoyable driving experience.

I always remember bumper stickers on the back of semis that read "Easy does it".

Almost 2 years now in our E450 rig and the ride is much better than the maiden voyage. The replacement shock absorber on the steering link made a big difference along with adjusting our tire pressure based on actual weight loading. It's a truck after all and will never ride like my Explorer but sure nice to have all the home comforts wherever we take it. I got to experience some good desert winds a few times and a bit different from our old cabover but I learned takin' it easy on the open road and listening to great tunes cures all the worries. What could be better?

Thor 2024 FourWinds 28Z Suspension Mods

Thanks to this forum of experts and advice just completed the listed suspension upgrades below to our 2024 Thor FWs 28Z. I have to say I am pleasantly surprised at the difference in handling qualities and stability. Definitely stabilizes the rock and roll and reduces driver steering workload. Thanks to all for the threads of wisdom and experience. Glad I did these mods.
