Gooseneck shock/air hitches

Thinking about trying one out. I have a 36ft. dual tandem flatbed that gets loaded with about 10,000lbs. I do a lot of interstate driving with it. It tows pretty nice behind my Duramax, but there is always some back and forth jerking that you can feel in the truck. Anyone have any input or reviews on using them? Looks like there's basically 2 popular options. One stays with your truck, and the other installs on the trailer neck. I made a post on facebook and had a couple of guys tell me that they wouldn't run without them, but had 1 guy tell me that he didnt notice any difference. Thoughts?

I've always wanted to try on, Josh. I like the trailer side ones since they will install by just replacing the tube, but I hate the idea of swapping a tube or buying three or four since I pull a different trailer each week it seems. If all your trailer have a round or square coupler tube and the insert pins the same, then swapping wouldn't be too hard I guess except I'm sure they aren't light. I think I'd rather have one mounted under the truck and hidden.

The push/pull of the two truck when I have the 4020 on the trailer is horrible so I know where you are coming from.

They say the new Chev chassis(2011+) takes all the negative gooseneck ride qualities away, especially the forward/backward jerking. I have no experience myself, but have sold two 2015's to fellow pullers here that towed with 05&06 chevys previously and they both say the same thing about the new chassis. One is a CC SB and one is a CC LB DRW.

I ordered a Cody Cushion brand. Supposed to be here this coming week. We'll see how it goes

I stiffened up my steel trailer.. no more bounce or f/r buck
Neck slop caused bucking

Added a 2*2*1/4 square tube bridge took care of my bounce


The croosman is substantially stiffer.. no bucking.. only bounce i get is if i over/under shot the sweet spot on the leaf springs on the truck... plus id bottom out both those due to pin weight i run

Our trailer is 11,800lbs empty, 14" main beams, 12" torque tube down the middle...we twisted a couple trailers over the years, so Corn Pro builds them so they won't twist for us now.

The will bounce you just a little from 63-66mph or so, only when empty. I don't see any flew really in the trailer, so I'd have to think that Adam is right that it's the trailer flex starting the whole deal.

Obviously, if you don't get it loaded right, it will bounce/buck a little on rougher roads, but I'm not sure how to get rid of that once you're up over 40K gross.

I know a gal that hauls horses across the country with a Kodiak with air ride and air at the hitch. She loves it because the air at the hitch takes the shock out of the weight on the truck and also smooths the ride for the horses in the trailer from the jounce coming up through the gooseneck from the truck.
