There is no CHF for an E450. That's for an F53 chassis.

chf fix

I put sumo springs and a track bar on my 450. Helped a lot. Next upgrades were to be heavier sway bar and safeTsteer.

Edited from my earlier terse response.

It sounds sort of like you're describing tail wagging.

When it happens do you find yourself sawing at the steering wheel to keep going in a straight line?

Or if you go over a sharp curb at a diagonal does the top rock back and forth viloently?

Or both.

I have a E 450 and replaced the rear sway bar with a Hellwig brand one, from Amazon.

No more watching in the mirrors for big rigs, to push me on the shoulder. Now its just a small correction of the steering wheel.

edinark I do feel like I have to saw at the steering wheel when I am pass by big rig to keep it in a straight line and no the rear does not sway side to side when going over a speed bump or thing like that.

My Class A is a Ford F53 chassis. In addition to the CHF, I also installed these. Work well enough that I don't get pushed around by the 18 wheelers any longer.

If I had a F450, a better sway bar in the rear and better shocks would be on my list for updating....

Have your alignment checked if you are all over the road. Part of my low cost upgrade.

I was wondering if you are experiencing tail wagging which may be addressed with a track bar to tie the rear axle to the frame. It would allow up and down movement but reduce the side-to-side movement of the rear of the coach.

The RV may have so much overhang behind the rear axle that the wind is pushing it around causing a tailwagging that'd require constant corrections at the steering wheel.
