Best Shocks to reduce Porpoising?

Last weekend we traveled down through Oklahoma and through the Dallas area down to Texas Motorplex, and oh man, some of those roads were pretty bad, especially South of the Indian nation turnpike. I had numerous times through that area the coach / trailer combo got to porpoising really bad, and dips and bumps bad enough we bottomed out the front suspension I think.

We rarely have any issues with this when pulling, even on sorta rough roads and bridges, but these were an exception. Anyone that pulls a trailer found some brand of shocks that improve that situation?

On my previous coach I installed Bilsteins. On my current coach I installed Koni's I like the Koni's better.

I haul a 20' enclosed trailer that weighs in at about 9,000 lbs and so far no problems with the Koni's

Koni EVO 99's worked wonders on the front of my rig. Already had Koni's all around but the 99's work better than the OEM adjustables. The EVO's are like a FSD but made for heavy rigs. My front axle is rated for 20,000#'s.

Since your porposing, that means your shocks are shot, so go with what your wallet can stand. I recently replaced the oem 13 year old shocks with Bilstein and it was a radical change for the better.

I don't think the ones I have on it now are totally shot or nothing, typically it doesn't do it with the big trailer behind us. Just crappy roads getting things rocking just right and too much for the shocks that's on it.

I do think I'll try some of those Koni's sometime this summer, heck might as well it can't hurt. Just recently put new tires, air bags, ball joints, tie rods and 4 wheel alignment so shocks will be cheap in comparison haha.

Are there after market sway bars available?

I installed a set from Source Engineering and pot holes smoothed out.

The Bilstein shocks I installed did wonders for thing too.

Summo springs, steering dampner, sway bars, track bar and will be gone. Down the road shocks as well. Just the nature of the build. They all do it there is a lot of weight to manage while going down the road. Downside is it's not cheap but you only do it once or at least once per coach. I'm on my second suspension upgrade. 2018 southwind in the shop now before the first trip.

Well front and rear are air springs, so no changing that side of it. Have to do some research about the anti-roll bars. I'll probably start with shocks first. Thinking about one of those air hitches too.

Bilstein's on mine never an issue with Porpoising at all. But don't over react for the bad Roads .

OK roads are like 3rd worst in the country.
Evaluate if you really need new shocks.
I've traveled Rt 69 many times, really bad. Most states are better.
