Ordered Lance struts today

They're not going to help on the concrete highway. Only adjusting your speed will make any difference.

Concur with the suggestions above..AND the truck mount hardware can be a PITA to install...I had to add another thru bolt to make mine stop rattleing after 10K...next thing The bracket for the underside of the cabover...make sure you find solid mounting place and if possible try to use bolts as long screws will work themeselves out and the holes become useless until you plug them and drill again...now here's the next thing: in my haste I forgot to unhook them when doing something to the TC and pulled the bracket off...so the screws just pulled out...so what would have happened if it had been bolts...damned if you do damned if you don't! On the rebuild I will install some good hardwood mountings in the cabover rails, but not reinstall the shocks until I have driven without them for a while...when I broke them I drove about 5000 miles and didn't miss them to got back home...so for me it is a toss up...maybe they are worth it maybe not...GOOD LUCK with yours I hope it helps with the situation you experience.

I use the camper struts and like them. They are not a fix-all. My whole rig tends to wobble more if I don't use them. They don't really 'hold' anything, but rather reduce the shock loading and movement just like a ....shock. Everything goes into slow-mo.I bought them in 2002 and feel naked without them. They are kind of like a girdle. Everything that can wobble stays in check.
Inspect the four, 3/8" bolts holding your bed to the truck frame. My passenger front bolt pulled through the bracket/mount and the bed was actually rocking on the frame for a short time until I discovered the culprit.
I used higher strength bolts this time all around and thick, wide fender washers so the bolts would not pull through. Not too tight though. A little give using locknuts or double nuts may help on rough roads. One of the hazards of a twisty frame.

It would be better to change shocks and add stabileloads or equivalent. Essentially, your suspension is out of balance if you are porposing.

I'll see how the struts work out, then figure out my next step. I am planning to get some better shocks, maybe some Ranchos. I put Bilstiens on it, and that was a big mistake, they are way too soft for this application. I should have known that when they list the same shock for a D1500 1/2 ton as they do for a D3500 1 ton dually.
Also, I am running air bags, and when I put 80 lbs or so in them to get the truck level, they so hard that the bumps in the road are brutal. If I let the air down, the truck sits on the overload springs, and the ride is equally brutal. I think my 20+ year old main leafs are sagged to much. A friend of mine had a similar situation. What he did was remove the overload springs and add 2 long leafs to the main springs. It worked for him, so I might try that as well.

Joel, I have them, and like them alot. But my experince is they DO not elimiate the bounce or porpising, but they do a great job of controling it. If your porpising is bad enough to consider selling it, you may have some other sort of problem with your setup. You gotta love the roads here in MN.

Hi Joel,
Very interested in the outcome. I think it makes sense to have the additional stability located up front.
