Bags, Timbrens or better shocks?

Any suggestions on smoothing out those highway whoop-de-doos? Just got back from a 3000 miles trip and at times the bouncing reminded me of an amusement park ride. I have a Ram 2500 with about 1500 pound tongue weight on the hitch.
Thanks

I have had both air bags and timbrens... My personal opinion is that I like the ease of installation and use of the timbrens over the air bags.

However, if the budget allows, an air bag set up with on board air compressor and switches in the cab to inflate and deflate the bags is the way to go as it will give you the capability of leveling out with more than just your one trailer...

still, my vote is for timbrens...

Sorry; I can not help you to much as I tow a fifth wheel and the ride quality is totally different do to the pin weight over the axle. I also have my truck set up for towing heavy loads and this also has effect the ride of my vehicle.

But you can read this thread from Turbo Diesel Register. Com about changing out shocks on a third gen truck. The poster installed Bilstein 4600 series shocks on his truck.

Good Luck

not saying air bags are bulky or a pain to use as they aren't but they do take some sort of user interface. I'm also not trying to say air bags have problems as I had my set for a number of years and abused the hell out of my last truck and they really held up well till the day i traded the truck...

neither option would be bad, i just like the concept of installing and forgetting...

I really like my antique airbags with the onboard compressor. It takes about a minute or less to set the pressure and I get to control it. My airbags/compressor unit is 15+ yrs old and have never had a leak or a problem.

New, properly matched shocks will smooth the ride. Nothing you can add will cure an overloaded situation. Before spending a dime on add ons you need to load up and get accurate scaled weights to determine what you really have.

Will knowing the exact weights cure anything? He knows what the situation is that he doesn't like, so add ons are his only option. New shocks might help, but airbags, etc are about his only options.

IMO timbrens are for folks that are maxing-out their rear axle weights...

When my '11 Ram 2500 gets bouncy, it's because I do not have ENOUGH weight on the rear springs and/or not enough tongue weight... My 2500 rides best with at least 15% on the tongue and at least 4500 total rear axle weight.

It may be just how I have my Equalizer 4 WDH setup, but if I don't carry as much firewood & gear in the pickup bed the ride gets bouncier... For the last trip I had 5000 on the rear axle & 3320 on the front & it was the smoothest ride yet. I also added a fiberglass cap this winter & believe its allowing some downward pressure on the rear.

Another suggestion that might help you out would be the addition of shocks to the camper if there isn't already a set there...

Some roads with certain rig combinations i feel are just bad combinations. My previous truck and trailer would pull just fine here in Nebraska but it seemed as soon as I crossed the river into Iowa all hell broke loose and we got that amusement park ride you are talking about.

I actually went as far as to have my work laser cut me a 1/2" thick steel plate that matched the tongue of my trailer to add 200 pounds of tongue weight... it helped greatly but didn't eliminate it... I feel that I had i added shocks to the trailer it would have behaved much nicer...

just a consideration... I believe OC has done a set or two and may have some more insight on it...

I hate to bring this up again but you can cure an overload situation depending on your truck. I have a 2500 GMC diesel and there is really no difference in a 3500 except for a few more leaf springs. I verified this with multiple dealers. So adding any kind of suspension enhancement can actually increase your payload, in this situation. But you need to know your truck.

But to the original question I am partial to timbrens. I had them on 3 trucks now. I always look at cost/benefit and the possibility for failure. Timbrens have really no parts that can fail.

I just installed a set of these Roadmaster Active Suspension Kits | Helper Springs | Overload Springs , and while I have not pulled a long trip yet, they really seem to help. Had air bags on my previous TV, and they were OK, but expensive to buy and install, and needed to be adjusted when the trailer was not hooked up .....

You have a 2500 truck that bounces like I you use to have. Equalizer BRAND hitch!!!! All problems gone!!!
No need to fool with the suspension if your not overloading. Do the hitch first!!!

I agree that a properly installed WDH with anti-sway is the first step. I used a 4 point Equal-I-zer.

Then I tried Timbrens, because they are relatively inexpensive and so easy to install. They worked great on my F-250. They do not affect stock handling because they only "kick in" when carrying a load. Also, I would have been able to return them (Amazon) if they were not to my liking. There are similar products such as Sumo Springs and Super Springs.

If Timbrens did not work well, my next choice would have been air bags, which are more expensive, especially if installed with an on board compressor and gauges. I think that might give more options if you are towing different trailers with different hitch weights and gross weight. The down side is maintenance and possibility of getting leaks. If you get air bags, I would make sure they have "jounce" feature so that they still protect the suspension if there is a major leak.

My Timbrens performed so well in improving towing - that was as far I needed to go.

Andersen WDH. No bounce.

You could try both - Timbrens and bags. Works for us. Put the Timbrens in first and there was some improvement, especially traveling along frost heaved prairie highways. The addition of bags improved things significantly. Ya, I know, different suspension but the point is... the Timbrens assist in controlling (cooling) the rebound, the bags assist in managing that rebound and the overall effectiveness of the suspension.

while a pain to install I would choose airbags any day over timbrens. I have timbrens in my present TV and had airbags in my last one....
not all trucks come with a camper package, but if you do have the extra leaf....with your truck loaded and the extra leaf about a 1/2 " from the nub that puts it into play, any time you hit a bump and the extra leaf [known as overload spring] hits the nub you'll get a double bounce and on semi smooth pavement you'll just go bouncing down the road...I get this on my present TV...all because I was trying to save a buck .

I use the timbrens. They are also intended to prevent sway. They are longer than the original snubbs on the truck which with the stock ones they never really touch the rear axle when the trailer is hooked up. That's why you bounce more. Installing the Timbrens makes them touch the axle and provides additional resistance to sway. After adjusting my 4 point WDH and adding these my sway and ride improved dramatically. Its like any thing else everyone has a preference.

With the condition of our roads today it's going to be hard to get any sort of smooth ride when towing TT. I had 5th wheels which towed so much better but as we go older it was harder to climb stairs . If I had to do again I would go back to a 5th wheel. Later RJD
